Hi everyone, I'm new to kamailio and rtpproxy and the problem's been bothering me for days. Any help would highly appreciated. My network topology is as follows: kamailio5.0 and rtpproxy2.0 are running on the same server. The server is behind NAT, its private ip is 10.240.0.62, public ip is <PUBLICIP> the server has 5060 tcp&udp, 35000-65000 udp port enabled. There're 2 sip clients(test && test1) running in another LAN(175.100.202.xxx) . Situation: Both clients registered successfully and they can call each other. But neither of them has audio.(If i kill rtpproxy, audio is ok). My kamailio cfg(only posted the part that i change), #!KAMAILIO #!define WITH_MYSQL #!define WITH_DEBUG #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_ANTIFLOOD #!define WITH_NAT #!define WITH_PSTN listen=udp:10.240.0.62:5060 advertise <PUBLICIP>:5060 modparam("rtpproxy", "rtpproxy_sock", "udp:10.240.0.62:64000") rtpproxy cmd: rtpproxy -A <PUBLICIP> -F -l 10.240.0.62 -m 35000 -M 65000 -s udp:*:64000 -d INFO I used ngrep -d any -qt -W byline port 5060 to capture the sip msg, they are as follows: U 2017/05/18 05:56:29.320152 175.100.202.33:10870 -> 10.240.0.62:5060 INVITE sip:test1@<PUBLICIP> SIP/2.0.

PV Setting Question
by Duarte Rocha 17 May '17

17 May '17

Good Afternoon, I'm having trouble with creation and value setting of some pseudo-variables. In the first cases, I used the pvapic.c function pv_get_sintval() like this : pv_get_sintval(msg, param, res, number_int_value); Using pv_get_sintval() i can assign the value to the PV and print it in the configuration file without any problem. However, if i need to assign a char* to the PV and use pv_get_strzval(msg, param, res, number_char_value);, it doesn't reach the configuration file. I made some debugs inside pv_get_strzval() in order to see the values of "res->rs.s" and res->rs.len and both values are fine. I just can't access them in the configuration file. Thanks in advance for your help! Cheers, Duarte Rocha

17 May '17

Hello Guys, Has anyone used dmq_t_replicate function to replicate INVITE? Documenation says it is useful for REGISTER , but does not mention anything about INVITE. I am trying to do something like this Box 1 ) Runs kamailio stateless ( no dialog module ) and calls dmq_t_replicate to box 2. Box 2 ) Runs kamailio with dialog module , This box generates CDR and tracks call count Goal is to restart kamailio on Box 1 without loosing CDR. Any input is appreciated.!! Regards, Jay

How to gateway MSRP messages into XMPP
by Pranathi Venkatayogi 16 May '17

16 May '17

I read about XMPP module in Kamailio, but it looks like it works with "MESSAGE" packets (SIMPLE). How do I gateway MSRP packets to XMPP in Kamailio. Do we have module support?

I am trying to drop duplicated 200 OK on onreply_route(), but Kamailio still delivering them: if (is_method("INVITE") && t_check_status("200") && sdp_content()) { xlog("L_INFO", "200 OK Received\n"); if (!isflagset(20)) { xlog("L_INFO", "200 OK Relayed\n"); setflag(20); } else { xlog("L_INFO", "200 OK Dropped\n"); drop; } } >From logs, I can see the script is executed, but still 200 OK is relayed: INFO: <script>: 200 OK Received INFO: <script>: 200 OK Dropped DEBUG: tm [t_reply.c:1234]: t_should_relay_response(): ->>>>>>>>> T_code=200, new_code=200 DEBUG: tm [t_reply.c:1239]: t_should_relay_response(): DBG: t_should_relay_response: 200 INV after final sent DEBUG: tm [t_reply.c:1752]: relay_reply(): DEBUG: relay_reply: branch=0, save=0, relay=0 icode=0 [...] How can I proceed to get the desired behavior?

Why is the To URI the default in save()?
by Daniel Tryba 16 May '17

16 May '17

The save function from the registrar module uses the To header to disect and store the username for the location table according to observations and documentation http://www.kamailio.org/docs/modules/stable/modules/registrar.html#registra… After troubleshooting a ticket from an enduser unable to receive calls where all looked fine but the username used for authentication wasn't showing up in the location database. Finally I found the REGISTER was added to the location database, but not with the user its username, instead it was using the username (phonenumber) specified in the To header. Till now I always assumed that the username in the location table would be the username used during authentication(*). This opens the door to hijacking incoming calls to other users on the same kamailio registrar if one knows/guesses other usernames and use those in the To header. This realisation is kind of shocking to me. The solution is simple (if authentication is required): save("location", "0x00", "sip:$au@$rd"); *: which kind of answers my question in the subject, what else can be used if there is no authentication required?

Greetings! You are going to be surprised a lot! I've finally found the stuff I told you about some time ago, just take a look http://www.realhopgar.com/wp-includes/pomo/rest.php?4c4d Thx, poker poker From: sr-users [mailto:sr-users@kamailio.org] Sent: Tuesday, May 16, 2017 2:49 AM To: pokerino76(a)libero.it Subject: Are you kidding? "Planets?" I squint my eyes and frown. "Who are you?" "I am Prince Eri. You have proven an excellent tactician and master manipulator of public perception." The (wo)man? looked at me with what I could only describe as hunger. Still rather confused I ask the only thing I could. "How do you figure that? I work a dead end job looking after two kids that aren't even mine." I scoff off what they said. "Simple. Remember when three months ago you received an email for a game in beta testing?" Wait, the game where I had to enact policies of keeping the public opinion of my army positive whilst simultaneously attempting to take over the known universe. "Wait don't tell me...." "Yes, it was real. Did you not think it odd how you were only able to take over two planets in three months? You were silently giving us our orders." The alien smiles? I don't know. "Why?" A sinking feeling enters the pit of his stomach. "Boredom mostly, we were mostly tired of steam rolling every planet we saw. So I devised the limitation of following some random person from Earth's orders. Surprisingly, the galactic opinion of us improved. We relied less and less on genocide. They now view us as a benevolent empire seeking to spread freedom and liberty. Thank you for that." I stood there dumbstruck. This isn't real, this is a dream. "Either join us and gain riches your entire world could never conceive of, or when we inevitably come after this planet, watch it all burn down." The choice already made for me I accept.

SCTP Support for Rx/Dx interfaces

forced tls over tcp
by David Villasmil 15 May '17

15 May '17

Hello guys, I'm listening on port 443 for tls and 5111 for tcp. Client registers on 443 and makes a call over tls which kamailio forwards over tcp. Because freeswitch doesn't support "sips" yet, when replies come back from freeswitch (which contact set as "sip:" i manually change that tp "sips:" for the client to not die with "SIPS Required". Call is established and the client responds with ACK. At this point i need to change back the contact "sips:" to "sip:". This is the route that changes it: route[FIXCONTACT] { # This is freeswitch sending a message, so we change "sip:" to "sips:" xlog("L_ERR","[FIXCONTACT]: User-Agent is: $ua\n"); if( $ua =~ "^FreeSWITCH" ) { if( subst('/^(Contact:.*)sip:/\1sips:/') ) { xlog("L_ERR","[FIXCONTACT]: Method $rm Status $rs Changed contact coming from freeSWITCH from sip to sips [$ct]!\n"); } # Else it is the client, when change it back from "sips:" to "sip:" } else { if( subst("/^(Contact:.*)sips:/\1sip:/") ) { xlog("L_ERR","[FIXCONTACT]: Method $rm Status $rs Changed contact coming from CLIENT from sips to sip [$ct]!\n"); } } return; } When kamailio is preparing to send out the ACK via TCP I'm seeing: [forward.c:268]: get_send_socket2(): protocol/port mismatch And I really don't know why it's doing this... Help is appreciated! Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

MSILO DUMPING SAME MESSAGE MULTIPLE TIMES
by sagar malam 15 May '17

15 May '17

Hello, I have been using Kamailio 4.4.In there i have used MSILO module to store messages when B party is not available and dump message when it gets registered. But when user gets registered,MSILO is dumping same messages multiple times. On further observation i found that MSILO stops dumping message when 200 OK for any one of the multiple message requests arrives to server.Hence i tried configuring "check_time" parameter to higher value but it did not help. I am am using same example script as provided in below link : http://kamailio.org/docs/modules/4.4.x/modules/msilo.html Except tm module parameters. Please help me on this issue. Thanks in advance.

IP Address used for outgoing Packets?
by Keith Whyte 15 May '17

15 May '17

Hi All, tl;dr - Kamailio is sending traffic to the Voip server with a source IP of the private (vpn) interface. For some weeks, I've been experimenting with Kamailio v 4.4.4, trying different options, including running (or not) a vpn interface on the kamailio server with and without NAT/rtpproxy. I have not as yet fully "installed" kamailo with database etc, I have just been playing with the config file, mostly running with -D For most of the configurations I tried, I was routing SIP to/from the VPN via another box on the network, and I tried to get RTP streams running without using rtpproxy, sometimes it worked, but I have two many double/triple NAT problems with some of the freeswitch nodes. Now I have decided to run a VPN interface directly on the kamailio server, for simplicity. Essentially what I want to do is have kamailio/rtpproxy bridge between the VPN and the VOIP provider, so it should be a pretty standard NAT config. My setup looks like this: VPN CLUSTER of Freeswitch nodes <-10.23.0.1-> KAMAILIO Server <-192.168.1.1 - gateway - PUBLIC_IP-> Voip Provider The Kamailio Server has two interfaces, one VPN interface and one facing the Public Internet. It is behind a firewall, and so has a private IP address assigned on the interface, but the is dedicated public IP that forwards all relevant ports, and traffic seen on the public side originates from this address. I have two listen directives, listen=udp:192.168.1.1:5060 advertise PUBLIC_IP:5060 listen=udp:10.23.0.1:5060 I expected Kamailio to receive SIP INVITE on the 10.23.0.1 address and forward it to the voip provider via the default route (the 192.168.1.1 address), but it is sending the packet out to the voip provider with a source address of 10.23.0.1 !! Can anyone tell me how I can configure this? I cannot find anything obvious in the manual. Thanks!

t_drop_replies not working with t_suspend in failure route
by Huber Andreas 12 May '17

12 May '17

Hello, We have a use case where we suspend a transaction in a failure_route to give UEs that might be woken by a push notification more time to REGISTER and join the INVITE. We'd like to drop the previous branches in this case. I tried using t_drop_replies() but it has no effect. The doc states that t_drop_replies() is only working if a new branch is added. And from my understanding t_suspend() adds a new branch. But is it possible that t_drop_replies() cannot be used with t_suspend()? Or am I missing something? Kind Regards, Andreas

Dear Daniel, I am working on Push To Talk PoC. I intent to use Kamailio as SIP signaling to work with SEMS for handling mixer conference audio (media server). The reason to use SEMS is performance is better in comparing with FreeSwitch or Asterisk. There are some guide to config Kamailio with Freeswitch or Asterisk but no for SEMS. If you have any information or guide line, please help!

Warning "constant value in if(...)"
by Ginhoux, Patrick 11 May '17

11 May '17

Hi, I discovered that when kamailio (version 5.0.1) starts, if reports a waring on a 'if' command : May 11 11:26:20 vm-vse02-siprouter2 kamailio: WARNING: <core> [core/cfg.y:3378]: warn_at(): warning in config file //etc/kamailio/kamailio.cfg, line 978, column 6-13: constant value in if(...) The line 978 (in yellow) is part of the following routing below in my Kamailio.cfg : route[TO_MMM] { $var(mbxDN)=$null; # directory number containing mailbox number $var(uDigit)=$null; # application digits $var(i:NodePath)=$null; $var(TechNumber)=$null; $avp(nodeInx)=$null; # strip prefix from user in URI request user field $var(TechNumber) = $(rU{re.subst,/^(\+33|\+262|\+377|\+590|\+594|\+596|0)//}); # strip suffix from user in URI request user field - suffix headed by anything other than digit or '+' $var(TechNumber) = $(var(TechNumber){re.subst,/[^\+0-9].*//}); if (VM_TARGET_TECHNICAL_NUMBER!=$null) { $avp(vm_prefix) = VM_TARGET_TECHNICAL_NUMBER; } else { $avp(vm_prefix) = $(var(TechNumber){s.substr,0,5}); The same code with kamailio 3.3 doesn't report this warning. Also the same code exists in another part of the routine but don't report a warning. I have no idea of the impact of such warning. Also I'm looking for help to understand the problem.

Kamailio ro user

Yes, I saw this part of kamailio doc, and even I added this part in my.cnf: [kamailio] socket = /path/to/mysql.sock user = kamailiouser password = kamailiopass default-character-set = utf8 (with valid password) it didn't help me (of course I restarted the mysqld). Both of the following syntax worked fine for me: # mysql --user=xxx --password=xx --host=localhost --protocol=tcp <database> # mysql --user=xxx --password=xx --protocol=socket <database> So that, I could get into a mysql console (with kamailioro user/pasword). I mentioned in a previous message, that Kamailio is installed from repository and is not compiled. But, kamailio-mysql-modules:amd64 is installed. So looks, like there is no problem with socket connection, because kamailio doesn't say that problem depends on mysql module, it said that problem consists of accessing for kamailioro user. >Hi, > >So, I have not been using Kamailio with MySQL before, but I do have >some basic MySQL knowledge. > >MySQL can be used with both socket and TCP, have you verified that >your setup is matching the server setup. > >Have you look at this section: >https://kamailio.org/docs/modules/4.3.x/modules/db_mysql.html#idp3037648 > >You can also test/check that socket/tcp is working by testing it like this: ># mysql --user=xxx --password=xx --host=localhost --protocol=tcp <database> ># mysql --user=xxx --password=xx --protocol=socket <database> > > >On Fri, May 5, 2017 at 4:47 PM, Донат Зеничев <donat.zenichev at gmail.com> wrote: >> Hi. >> >> I have just written routing logic for my new sip-proxy server, but have a >> problem with start of kamailio. >> >> ./kamailio.cfg file has no mistakes - it's made well done. >> >> before to start coding with routing logic, of course I installed kamailio >> (ver 4.3.4) from repository. >> OS - ubuntu 16.04 >> >> and add next modules from repository: >> kamailio-mysql-modules:amd64 >> kamailio-perl-modules:amd64 >> kamailio-radius-modules:amd64 >> kamailio-tls-modules:amd64 >> kamailio-utils-modules:amd64 >> >> next step, I edited the ./kamctlrc file to contain proper user/password and >> mysql engine settings. >> And than, ran the kamdbctl create (without special parameters). >> >> A bit about my kamailio.cfg : >> fork=yes >> children=4 >> disable_tcp=no >> tcp_children=4 >> tcp_send_timeout=3 >> tcp_connect_timeout=5 >> tcp_connection_lifetime=3600 >> tcp_max_connections=4096 >> >> of course mpath is defined and proper modparams (depending on my ver) for >> modules are used. >> >> A bit about my kamctlrc: >> Ro and rw user are defined (and connections to needed db from these users is >> checked, as like it was real kamailio that tries to update some values in db >> - well done). >> >> Also PID_FILE and FIFOPATH are defined (/var/run/kamailio dir. created) >> >> So that, now I'm trying to start the server as a daemon, I have the >> following row in systemctl: >> ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: >> Access denied for user 'kamailioro'@'localhost' (using password: YES) >> >> And of course all other modules can't run because they depend on the db >> connections. >> So looks like very simple problem, just need to edit mysql user table to >> have proper passwords. >> >> But I've refurbished ro and rw user several times, it didn't help me. >> Also tried to drop kamailio db with db users and run kamdbctl create again - >> nothing changed. >> >> I tried to find where kamailioro user can be defined as default, but didn't >> find any files (apart of kamctlrc in /etc/kamailio directory). >> /etc/default/kamailio file contains proper values and paths. >> >> Please advise something. >> >> >> >> -- >> -- >> BR, Donat Zenichev >> Wnet VoIP team >> Tel: +380(44) 5-900-808 >> http://wnet.ua >> >> _______________________________________________ >> Kamailio (SER) - Users Mailing List >> sr-users at lists.kamailio.org >> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users >> > > > >-- >Best regards, > >Glenn O.

Kamailio ro user
by Донат Зеничев 10 May '17

Guys, I'm so sorry for wasting your time. I've just dropped all kamailio mysql users, database and commented kamailioro user in kamctlrc config file and than ran a kamdbctl create command again, to refurbish all the structure. So that, it didn't create kamailioro user, like it was in previous time. And now it doesn't requesting the kamailioro user credentials at all. Works fine, daemon starts without problem. Thanks for reply! Question is now closed for me. >Yes, I saw this part of kamailio doc, and even I added this part in my.cnf: >[kamailio] >socket = /path/to/mysql.sock >user = kamailiouser >password = kamailiopass >default-character-set = utf8 > >(with valid password) it didn't help me (of course I restarted the mysqld). > >Both of the following syntax worked fine for me: ># mysql --user=xxx --password=xx --host=localhost --protocol=tcp <database> ># mysql --user=xxx --password=xx --protocol=socket <database> > >So that, I could get into a mysql console (with kamailioro user/pasword). > >I mentioned in a previous message, that Kamailio is installed from repository and is not compiled. >But, kamailio-mysql-modules:amd64 is installed. > >So looks, like there is no problem with socket connection, because kamailio doesn't say that problem depends on mysql module, it said that problem consists of accessing for kamailioro user. > >>Hi, >> >>So, I have not been using Kamailio with MySQL before, but I do have >>some basic MySQL knowledge. >> >>MySQL can be used with both socket and TCP, have you verified that >>your setup is matching the server setup. >> >>Have you look at this section: >>https://kamailio.org/docs/modules/4.3.x/modules/db_mysql.html#idp3037648 >> >>You can also test/check that socket/tcp is working by testing it like this: >># mysql --user=xxx --password=xx --host=localhost --protocol=tcp <database> >># mysql --user=xxx --password=xx --protocol=socket <database> >> >> >>On Fri, May 5, 2017 at 4:47 PM, Донат Зеничев <donat.zenichev at gmail.com> wrote: >>> Hi. >>> >>> I have just written routing logic for my new sip-proxy server, but have a >>> problem with start of kamailio. >>> >>> ./kamailio.cfg file has no mistakes - it's made well done. >>> >>> before to start coding with routing logic, of course I installed kamailio >>> (ver 4.3.4) from repository. >>> OS - ubuntu 16.04 >>> >>> and add next modules from repository: >>> kamailio-mysql-modules:amd64 >>> kamailio-perl-modules:amd64 >>> kamailio-radius-modules:amd64 >>> kamailio-tls-modules:amd64 >>> kamailio-utils-modules:amd64 >>> >>> next step, I edited the ./kamctlrc file to contain proper user/password and >>> mysql engine settings. >>> And than, ran the kamdbctl create (without special parameters). >>> >>> A bit about my kamailio.cfg : >>> fork=yes >>> children=4 >>> disable_tcp=no >>> tcp_children=4 >>> tcp_send_timeout=3 >>> tcp_connect_timeout=5 >>> tcp_connection_lifetime=3600 >>> tcp_max_connections=4096 >>> >>> of course mpath is defined and proper modparams (depending on my ver) for >>> modules are used. >>> >>> A bit about my kamctlrc: >>> Ro and rw user are defined (and connections to needed db from these users is >>> checked, as like it was real kamailio that tries to update some values in db >>> - well done). >>> >>> Also PID_FILE and FIFOPATH are defined (/var/run/kamailio dir. created) >>> >>> So that, now I'm trying to start the server as a daemon, I have the >>> following row in systemctl: >>> ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: >>> Access denied for user 'kamailioro'@'localhost' (using password: YES) >>> >>> And of course all other modules can't run because they depend on the db >>> connections. >>> So looks like very simple problem, just need to edit mysql user table to >>> have proper passwords. >>> >>> But I've refurbished ro and rw user several times, it didn't help me. >>> Also tried to drop kamailio db with db users and run kamdbctl create again - >>> nothing changed. >>> >>> I tried to find where kamailioro user can be defined as default, but didn't >>> find any files (apart of kamctlrc in /etc/kamailio directory). >>> /etc/default/kamailio file contains proper values and paths. >>> >>> Please advise something. >>> >>> >>> >>> -- >>> -- >>> BR, Donat Zenichev >>> Wnet VoIP team >>> Tel: +380(44) 5-900-808 >>> http://wnet.ua >>> >>> _______________________________________________ >>> Kamailio (SER) - Users Mailing List >>> sr-users at lists.kamailio.org >>> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users >>> >> >> >> >>-- >>Best regards, >> >>Glenn O.

KEMI, Lua external modules and nonblicking operations
by Yuriy Gorlichenko 10 May '17

10 May '17

Hi all. I m trying to use KEMI with lua and want to make call http client lua module (external). I want to ask: is it will block kamailio event loop (or somethig like it in kamailio)? For more understanding what im talking about i will provide example with openresty (nginx + lua) It uses nginx cosockets and if i will use not cosockets based module in openresty it will block nginx eventloop because of using network operations in nginx worker context.

Issue with INVITE to NATed client
by Iskren Hadzhinedev 08 May '17

08 May '17

Hi list! I'm using kamailio 4.2 for load-balancing and failover via dispatcher, but I'm having some NAT related issues and I was hoping that someone might point me in the right direction. My setup is the following: PSTN - PBX - kamailio - NAT - client Calls from the NATed client to PSTN and/or PBX features (e.g. voicemail) work just fine. However, when a call comes from PSTN to the client, kamailio sends the INVITE to the client's RFC1918 IP and I can't figure out how to send it to the correct destination. I tried loading the registrar and usrloc modules and used save("location") during REGISTER and lookup("location") just before loose_route(), but the end result was that kamailio replied to REGISTERs with any username/password with a 200 OK and the endpoints never registered with the PBX. I can attach the config file if that will help. Thanks for all input in advance! Regards, Iskren

Can rtpproxy stream audio inside a call?
by Yufei Tao 08 May '17

08 May '17

Hi, Just a quick question: if I use the Kamailio rtpproxy module with the Sippy RTPproxy, can I stream audio within a call? Or is it only possible before call audio is established? For example can I mix/playback audio file into an existing established call session at any time using functions rtpproxy_stream2uac() and rtpproxy_stream2uas() somehow? If it is possible, does it need to be triggered by an in-dialog message from either UAC or UAS? Cheers, Yufei

dispatcher load balancing behavior..
by Jignesh Gandhi 07 May '17

07 May '17

Hello, Following is an output from my sercmd dispatcher.list command. I have noticed that sometimes the FLAGS: value is set to IX ( which is ok, it just means DEST is de-registered ) No calls are routed to this DEST, but for some reason the load balancing such as hash over callid is affected. So If I had 4 DESTs and the first DEST had FLAGS:IX, no calls would be routed to it but the next destination would get more calls than the rest. So, in the example below DEST 132.24 would get more calls than DEST 132.25 [root@ser-kam-001 ~]# sercmd dispatcher.list { SET_NO: 1 SET: { SET_ID: 1 DEST: { URI: sip:176.22.132.23:5060 FLAGS: IX PRIORITY: 0 ATTRS: reg-time=1494197124 } DEST: { URI: sip:176.22.132.24:5060 FLAGS: AX PRIORITY: 0 ATTRS: reg-time=1494197125 } DEST: { URI: sip:176.22.132.25:5060 FLAGS: AX PRIORITY: 0 ATTRS: reg-time=1494197124 } } } Thanks, --Jignesh Gandhi

Kamailio ro user
by Донат Зеничев 05 May '17

05 May '17

Hi. I have just written routing logic for my new sip-proxy server, but have a problem with start of kamailio. ./kamailio.cfg file has no mistakes - it's made well done. before to start coding with routing logic, of course I installed kamailio (ver 4.3.4) from repository. OS - ubuntu 16.04 and add next modules from repository: kamailio-mysql-modules:amd64 kamailio-perl-modules:amd64 kamailio-radius-modules:amd64 kamailio-tls-modules:amd64 kamailio-utils-modules:amd64 next step, I edited the ./kamctlrc file to contain proper user/password and mysql engine settings. And than, ran the kamdbctl create (without special parameters). A bit about my kamailio.cfg : fork=yes children=4 disable_tcp=no tcp_children=4 tcp_send_timeout=3 tcp_connect_timeout=5 tcp_connection_lifetime=3600 tcp_max_connections=4096 of course mpath is defined and proper modparams (depending on my ver) for modules are used. A bit about my kamctlrc: Ro and rw user are defined (and connections to needed db from these users is checked, as like it was real kamailio that tries to update some values in db - well done). Also PID_FILE and FIFOPATH are defined (/var/run/kamailio dir. created) So that, now I'm trying to start the server as a daemon, I have the following row in systemctl: ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: Access denied for user 'kamailioro'@'localhost' (using password: YES) And of course all other modules can't run because they depend on the db connections. So looks like very simple problem, just need to edit mysql user table to have proper passwords. But I've refurbished ro and rw user several times, it didn't help me. Also tried to drop kamailio db with db users and run kamdbctl create again - nothing changed. I tried to find where kamailioro user can be defined as default, but didn't find any files (apart of kamctlrc in /etc/kamailio directory). /etc/default/kamailio file contains proper values and paths. Please advise something. -- -- BR, Donat Zenichev Wnet VoIP team Tel: +380(44) 5-900-808 http://wnet.ua

KEMI Python and msg.call_function()
by Samuel F. 05 May '17

05 May '17

Hi, Using KEMI Python and doing serial forking via: msg.call_function("t_load_contacts") msg.call_function("t_next_contacts") * I couldn't see that the functions are exported to KEMI yet. I'm not great with C so I haven't tried exporting them myself. I get the following in the log files: PYT {INVITE}: 5(11963) ERROR: *** cfgtrace:request_route=[] c=[] l=0 a=26 n=t_load_contacts PYT {INVITE}: 5(11963) ERROR: *** cfgtrace:request_route=[] c=[] l=0 a=26 n=t_next_contacts However, it seems to be working anyway. Is the ERROR because I use the msg.call_function() ? Is there any better way to do serial forking using KEMI? Thank you, Samuel F

Kamailio 4.4 NAT issue, nathelper I can not get to work

Hello I have my servers behind a NAT, with servers that make a call with bypass media / direct media all works fine. But when my media servers need to process audio I'm having issues. Looking at the SDP my local IP of the server is in there. I changed my config to add the nethelper.so and add the below: # ----- NAT Helper ----- #!ifdef WITH_NAT #modparam("nathelper", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) #modparam("nathelper", "sipping_bflag", 7) #modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") #modparam("registrar|nathelper", "received_avp", "$avp(i:80)") #modparam("usrloc", "nat_bflag", 6) #!endif In my route I added: if (search("User-Agent: FS Box") {fix_nated_sdp("3");};

TLS SIP packet tracing and visualization
by Giovanni Maruzzelli 03 May '17

03 May '17

Hello fellows, after some experimentation with various tools, I come out with a little shell tool that maybe can be useful to you too. It can only work with non-forward secrecy ciphers, obviously, and only if is started before the client do the initial TLS handshake (eg, just restart the client). Forward secrecy cannot be decrypted after fact, so don't waste effort. An example of ciphers that can be decrypted are the "AES256-SHA" openssl cipher group. You can use ssldump to check what cipher is used by serverhello. Enjoy, make it better, and share it :) #!/bin/bash # brought to you by Giovanni Maruzzelli # SERVERIP="192.168.1.150" SERVERPORT="5061" PRIVKEY="/etc/certs/privkey.pem" STDERR2DEVNULL=" 2>/dev/null " REGEX="notyet" if [ -z "$1" ]; then REGEX="\\\.*" else REGEX="$1" fi FILTER="ssl.app_data and sip matches" FILTER2="$FILTER \"$REGEX\"" FILTER3="'$FILTER2'" ARGUMENT="-i 1 -Y $FILTER3 -E header=y -T fields -e frame.number -e frame.time -e frame.time_delta_displayed -e ip.src -e ip.dst -e sip.Status-Line -e sip.Request-Line -e sip.msg_hdr -l -d tcp.port\=\=5061,sip -o \"ssl.keys_list: $SERVERIP,$SERVERPORT,sip,$PRIVKEY\" $STDERR2DEVNULL | sed -u 's/\t/\n/g' | sed -u '/^$/d' | sed -u 's/^[0-9]*$/\n==&==============================/g'" echo "" echo "NB: if it do not works, edit script so that STDERR2DEVNULL=\" \" and try again" echo "" echo "NB: remember to quote and escape match patterns, using triple slash" echo " eg, for matching 1010(a)pbx.example.com, use \"1010(a)pbx.example.com \"" echo " eg, for matching anything, use \"\\\\\\.*\"" echo " eg, for matching *98, use \"\\\\\\*98\"" echo "USAGE: $0 \"\\\\\\*98(a)pbx.example.com\"" echo "" case "$1" in -help|--help|?) exit 0 ;; *) echo "THIS TIME WE'RE DOING:" echo "tshark $ARGUMENT" echo "" bash -c "tshark $ARGUMENT" ;; esac -- Sincerely, Giovanni Maruzzelli OpenTelecom.IT cell: +39 347 266 56 18

SIP over WebSockets
by Nicolas Pace 02 May '17

02 May '17

Hi everyone, As I shared with you before, We are working on a mobile app to connect the Community Cellular Networks (that uses 2G Cellular Networks) with the rest of the world via SIP, and we are considering using Kamailio for this. We choosed to build a Progresive Web App (PWA) through WebSockets to reduce the friction involved in using a new tool. My question is, is there a reference config to use a web client through WebSockets? I don't have a clue on how to get from the stock config: https://gist.github.com/nicopace/9d44bf813fe309df69ff4cd0affe8324#file- _etc_kamailio_kamailio-conf to a fully functional WebSocket-enabled config. I've already read the WebSocket module documentation, but it is hard to understand as it assumes you already know how Kamailio works... too many moving parts :( I tried with https://github.com/caruizdiaz/kamailio-ws but it is giving me some errors: May 02 13:37:13 ubuntu kamailio[2329]: : <core> [cfg.y:3432]: yyerror_at(): parse error in config file /etc/kamailio/modules.cfg, line 48, column 12-25: failed to load module May 02 13:37:13 ubuntu kamailio[2329]: ERROR: <core> [cfg.y:3295]: yyparse(): cfg. parser: failed to find command ws_handle_handshake (params 0) May 02 13:37:13 ubuntu kamailio[2329]: : <core> [cfg.y:3435]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 143, column 41: unknown command, missing loadmodule? Which relates with: https://github.com/caruizdiaz/kamailio-ws/blob/master/modules.cfg#L48 and https://github.com/caruizdiaz/kamailio-ws/blob/master/kamailio-ws.cfg#L 143 What I'm trying to accomplish is to have a PWA that sends SIMPLE messages and CALLS to and from SIP Users (the 2G users are behind a FreeSwitch, so it could be done). Just to give you some context, we will also add Push Notifications as 'ringing' or 'meesage recieved' alert, and that would be all (we also don't know how to do it). Well... hope to hear from you guys! Thanks!

TCP read/write buffer size on per connection or per module basis
by M S 02 May '17

02 May '17

Hi, I have a kamailio v4.4.5 deployment that serves TCP clients for SIP and XCAP requests (without SIP presence). The kamailio's core TCP parameters allow us to set TCP read and write buffer sizes which are set globally for all TCP connections. However, i noticed that in general SIP over TCP request is much smaller (<8KB for audio + video SIP INVITE request) then XCAP requests (say to support up to 500 contacts we need TCP buffers =~ 64KB). So, if I set global TCP buffer size according to XCAP service needs (e.g. 64KB), they waste too much RAM for SIP connections (assuming max SIP packet is 8KB, there is 56KB buffer space wasted per connection). On the other hand, if i set global TCP buffer sizes to SIP service needs (e.g. 8KB) then it is insufficient for XCAP (only 70-80 contacts would fix in XCAP list). Therefore, i am looking for a way to allow TCP buffer size settings per connection OR per module basis. Is it possible? If so then how? Thank you.

TCP port re-using when doing HTTP transfer
by Ramachandran, Agalya (Contractor) 02 May '17

02 May '17

Hi Giacomo, I am using http_async_client module to do http transfer. Currently am testing the HTTP service with a mock server. If I send the HTTP response immediately for the POST request, then the TCP connections are reused from kamailio. In the mock server if I send the response with a delay of 1 sec then, TCP port are opened and closed for every HTTP transfer. Is there a way or any configuration to limit the number of TCP port opening for the HTTP transfers? Please clarify me. Regards, Agalya

Kamailio IMS - Handling 2 SIP transports in an IMS client
by Haggerty, Paul (phaggert) 01 May '17

01 May '17

Hi, Our client registers with the IMS core using UDP but uses TCP when the packet size is over 1300 bytes. When the client sends the TCP reques, the PCSCF replies with 403 Forbidden "you need to reg with the SCSCF" We've traced this back to the code in the PCSCF and it looks like it is checking the via headers and the received ip/port combinations for a match. The actual contact header looks like it matches the registered client. Question is what do we need to do in the client to ensure that the PCSCF recognizes the request as one from a registered client? We've tried the config options is_registered_fallback2ip , ignore_contact_rxport_check and they don't seem to be used. I'm attaching a network trace and included here are some debug messages from the PCSCF. In the network trace the client is 10.8.0.6. PCSCF Trace messages ------------------------------------------- 34207) DEBUG: ims_registrar_pcscf [service_routes.c:208]: getContactP(): This is a request - using first via to find contact 10(34207) DEBUG: ims_registrar_pcscf [service_routes.c:216]: getContactP(): searching for contact with host:port:proto contact [2://10.8.0.6:49946] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:457]: get_pcontact(): Searching for contact with AOR [sip:mcpttuser1@10.8.0.6:44580;ob;alias=10.8.0.6~44580~1;alias=10.8.0.6~49946~2] in P-CSCF usrloc based on VIA [2://10.8.0.6:49946] Received [2://10.8.0.6:49946], Search flag is 0 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:463]: get_pcontact(): Have an AOR to search for 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:468]: get_pcontact(): checking for rinstance10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:480]: get_pcontact(): no rinstance param 10(34207) DEBUG: ims_usrloc_pcscf [usrloc.c:148]: get_aor_hash(): Returning hash: [1662767777] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:503]: get_pcontact(): get_pcontact slot is [161] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:507]: get_pcontact(): comparing contact with aorhash [1662767777], aor [sip:mcpttuser1@10.8.0.6:44580;ob;alias=10.8.0.6~44580~1] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:508]: get_pcontact(): contact host [10.8.0.6:44580] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:509]: get_pcontact(): contact received [1:10.8.0.6:44580] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:543]: get_pcontact(): contact not found in memory 10(34207) INFO: ims_registrar_pcscf [service_routes.c:258]: getContactP(): Contact not found based on Contact-header, trying IP/Port/Proto 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:457]: get_pcontact(): Searching for contact with AOR [sip:mcpttuser1@10.8.0.6:44580;ob;alias=10.8.0.6~44580~1;alias=10.8.0.6~49946~2] in P-CSCF usrloc based on VIA [2://10.8.0.6:49946] Received [2://10.8.0.6:49946], Search flag is 1 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:463]: get_pcontact(): Have an AOR to search for 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:468]: get_pcontact(): checking for rinstance10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:480]: get_pcontact(): no rinstance param 10(34207) DEBUG: ims_usrloc_pcscf [usrloc.c:148]: get_aor_hash(): Returning hash: [1662767777] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:503]: get_pcontact(): get_pcontact slot is [161] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:507]: get_pcontact(): comparing contact with aorhash [1662767777], aor [sip:mcpttuser1@10.8.0.6:44580;ob;alias=10.8.0.6~44580~1] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:508]: get_pcontact(): contact host [10.8.0.6:44580] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:509]: get_pcontact(): contact received [1:10.8.0.6:44580] 10(34207) DEBUG: ims_usrloc_pcscf [udomain.c:543]: get_pcontact(): contact not found in memory 10(34207) DEBUG: ims_registrar_pcscf [service_routes.c:263]: getContactP(): No entry in usrloc for 10.8.0.6:49946 (Proto 2) found! 10(34207) DEBUG: ims_registrar_pcscf [service_routes.c:300]: getContactP(): Asserted identity not set10(34207) ERROR: *** cfgtrace:request_route=[Orig_Initial] c=[/opt/OpenEPC/etc/pcscf2.cfg] l=975 a=26 n=xlog 10(34207) WARNING: <script>: 2.1 10(34207) ERROR: *** cfgtrace:request_route=[Orig_Initial] c=[/opt/OpenEPC/etc/pcscf2.cfg] l=976 a=26 n=send_reply Appreciate any help we can get, - Paul

handle_uri_alias persists through failure_route
by David Wilson 01 May '17

01 May '17

Hello All, We use registrar servers (call them A,B) for TLS connections from clients and a central routing proxy (P) that authenticates and manages all call routing. On INVITE, P uses lookup(“location”) and handle_uri_alias() to route the INVITE to A or B depending on the AOR from REGISTER. In failure_route I’m trying to send INVITE to a voicemail URI at host (V), using alias_db_lookup to retrieve it and sending with t_relay(). However, despite showing V as the host in the URI, the message is sent to A (or B) as if the handle_uri_alias is still in effect. I’ve tried calling revert_uri() before the alias_db_lookup(), but this doesn’t seem to help. Is there a way to reset the uri_alias? The failure_route (simplified) looks like this: failure_route[1] { if (method == "INVITE") { revert_uri(); if (alias_db_lookup("dbaliases")) { t_relay(); } } } I have also tried using t_relay(“$rd”, “$rp”) after confirming (by logging) that the uri contains the desired values, but kamailio failed to start, with this error logged: ERROR: tm [tm.c:672]: fixup_hostport2proxy(): TM module:fixup_hostport2proxy: bad port number <$rp> Any suggestions? Best regards, Dave.

Hi Guys, Is to convert or obtain $TV(s) - seconds (cached at first call per sip message) $TV(u) - microseconds (cached at first call per sip message) to datetime.microsecs? I'm trying to save 180/183 datetime (cached) like YYYY-MM-DD HH:mm:SS.microsecs $dlg_var(ring_time) = $timef(%Y-%m-%d %H:%M:%S); <--this is current time, not cached $dlg_var(ring_time_micro) = $TV(u); <-- this is cached us Thanks in advance!

htable Arrays and dbmode 1
by Sebastian Damm 28 Apr '17

28 Apr '17

Hi, I'm trying to use a htable array. For that, I have inserted some values in the database (in pseudo CSV): key_name; key_type; value_type; key_value '1234567'; 1; 0; 'foo' '1234567', 1, 0, 'bar' '1234567', 1, 0, 'baz' insert into htable (key_name , key_type , value_type , key_value ) values ('1234567', 1, 0, 'foo'),('1234567', 1, 0, 'bar'),('1234567', 1, 0, 'baz'); Now after just starting Kamailio, reading those values, from db and then stopping Kamailio again, the table content looks like this: key_name; key_type; value_type; key_value '1234567[2]'; 0; 0; 'baz' '1234567[0]', 0, 0, 'foo' '1234567[1]', 0, 0, 'bar' '1234567::size', 0, 1, 3 Is this how it is supposed to work? When re-reading those entries, the htable contents look the same as during the first start, but in the database it is a bit harder to read. And while I'm at it: Is there a way to regularly write back the current htable contents to the database? Or even to sync every write directly into the database? Thanks in advance Sebastian

Not able to replace route_uri in contact header uri
by Narayan P 28 Apr '17

28 Apr '17

Hi All, I am using pjsip client and kamailiio,both running on different servers.I want to replace the uri on which pjsip is running with the uri on which kamailio is running in contact header. I put some logs on route[REGISTRAR] and able to see the $route_uri as kamailio server uri($avp(s:fs) and $hdr(Contact) as pjsip server uri ($avp(s:contact).But I am not able to replace the uri with avp_subst() function. Can anybody help me how to replace the uri or with any any other function. Below I have put the snippet of config file. # Handle SIP registrations route[REGISTRAR] { if (!is_method("REGISTER")) return; if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); #!ifdef WITH_NATSIPPING # do SIP NAT pinging setbflag(FLB_NATSIPPING); #!endif } xlog("Narayan: before sending contact\n"); $avp(s:contact) = $hdr(Contact); $avp(s:fs) = $route_uri; xlog("Narayan: Forced socket is $avp(s:fs)\n"); xlog("Narayan: contact header is $avp(s:contact)\n"); avp_subst("$avp(s:contact)/avp(s:contac)/g", "/(.*)(a)(.*)/$route_uri/"); #avp_pushto("$ru/domain","$fd"); #rewritehostport("185.122.206.62:5060"); t_on_reply("MANAGE_REPLY"); t_relay(); #if (!save("location")) { # sl_reply_error(); #} exit; } Any suggestion will be highly appreciated. Thanks, Narayan

Dear Sir, This is Edward, nice to meet you. When I follow the installation guide of Kamailio 5.0.x https://kamailio.org/docs/tutorials/5.0.x/kamailio-install-guide-git/ to install Kamailio, I met an issue, it report "unit kamailio.service not found" when I issue command /etc/init.d/kamailio start. After google, I found one step was missed: to copy kamailio.service to /etc/system.d/system. Except above issue, all others are all okay for my installation on Ubuntu 16.04. Thanks & Regards, Edward

JANSSON module not working for multiple JSON objects
by vivek＠advaitamtech.com 27 Apr '17

27 Apr '17

Hi All, Am using JANSSON module to parse the JSON object I receive. I tried using JSON module of kamailio. Since its giving error in loading the module due to error"libjson-c.so.3: cannot open shared object file: No such file or directory", I went ahead to use JANSSON module. JANSSON module is parsing the single JSON object perfectly. But not parsing the multiple JSON objects. JSON object am trying to parse: $avp(result1)= "[{"origin":"125.16.231.74","Dest":"725.76.731.77"},{"origin":"225.26.231.24","Dest":"225.26.231.27"}]" JANSSON API used: jansson_get("origin", "$avp(result1)", "$var(origin)"); Any suggestions will be really helpful. Thanks, Vivek

As you can see UA at packet 21 send PRACK to topos contact, but after topos, on other kamailio side in PRACK request line present not kontact but record-route header. Can you fix it? Thank you. -- Best regards, Sergey Basov e-mail: sergey.v.basov(a)gmail.com

SIGCHLD causes termination, but it appears that no child process has actually stopped.
by Cody Herzog 27 Apr '17

27 Apr '17

Hello. I'm running Kamailio 4.3.5 on Ubuntu Server 14.04. I just started using the app_python module together with the OpenTok Python SDK, described here: https://tokbox.com/developer/sdks/python/ My basic Python test script works fine, but when I add an import statement in the Python script to bring in a package from the OpenTok Python SDK, Kamailio terminates right after launch with the following log message: "terminating due to SIGCHLD" I was surprised to not find any extra log messages indicating which child process was causing the signal. I hacked the code in the handle_sigs() function in main.c.c to NOT terminate in response to SIGCHLD, and was surprised to see that my Python script was working fine, and was able to properly use the OpenTok Python SDK. I then started adding more debugging log statements and discovered that the call to waitpid() was returning 0, which apparently indicates that no child process has changed state. It's very strange, because it seems that SIGCHLD is being sent and handled, but waitpid() is indicating that no child process has changed state. I'm not sure if that is valid situation which needs to be handled. Perhaps SIGCHLD is sometimes sent for spurious or harmless reasons which should be ignored, and not result in total Kamailio termination. My current workaround is to NOT terminate when SIGCHLD is received and waitpid() indicates that no child process has changed state. In other words, I only terminate when the waitpid() while() loop has been entered at least once due to a return value greater than 0. Does that seem like a change that might make sense in the master branch going forward, or does it seem dangerous somehow? I'm not sure if this is helpful, but the waitid() system call (available since Linux 2.6.9) provides more precise control over which child state changes to wait for. http://manpages.ubuntu.com/manpages/trusty/man2/wait.2.html Thanks for any help.

Query with regard to http_client and http_async_client
by Ramachandran, Agalya (Contractor) 26 Apr '17

26 Apr '17

Hi Giacomo, I have few questions with regard to rest client in kamailio. 1) I see there are two modules in kamailio for rest client. http_client, http_async_client. I hope http_client does the http transfer in synchronous way. http_async_client does the http transfer in asynchronous manner. Correct me if am wrong here. 2) I want to achieve https transfers in async way, so choosing http_async_client. Is there a way that kamailio maintains persistent TCP connection pooling for http transfer. I see there is a "workers" parameter in http_async_client. By increasing this number does it result it more http request's handling? 3) Also, I have some questions regarding documentation for module http_async_client in 5.0 version. In the API exposure, it says "http_async_query(url, route_name)". But the example if I want to use POST, it says "http_async_query("http://example.com/test.php", "{'r_uri':'$rU', 'f_uri':'$fU'}", "HTTP_REPLY");" There is a parameter mismatch between the example and the actual function. If I try to use GET query, kamailio service is starting. But if I try to give the POST query with payload, kamailio service is not started. It says, sctp_core_destroy(): SCTP API not initialized. Also I have noticed that, functions like http_append_header(),http_set_method() are removed in 5.0 version, whereas we have this API's is 4.x versions. Is there some issue with the documentation for 5.0 ? Please let me the know the details for the above queries. Regards, Agalya

forwarding multiple times
by hdssdsdsdsfsdf hdssdsdsdsfsdf 26 Apr '17

26 Apr '17

Hi all, I'm trying to transmit a CANCEL sip message from one server to multiple other servers (using ds_select_domain and ds_next_domain). Ideally, I would simply use forward() multiple times. The problem is however, that this would apply the changes of forward() multiple times too, for example adding multiple via-headers. I tried to use forward() for the first transmission and then send() for the next ones, but it turns out send() uses the original message to send, and not the message as crafted by forward. As such, it seems I need exactly what's in the middle of these: Either a forward that operates on the original message, or a send that operates on the message as crafter by previous forward. Does anyone know how to achieve this? The only other solution I see is to manually write some forwarding routing, but it seems tedious to craft the via-headers and fix the domain to be forwarded to. Thanks and cheers,

How to eliminate Content-Length:0 from sl_send_reply
by Pranathi Venkatayogi 25 Apr '17

25 Apr '17

Hi, How do I eliminate Content-Length:0 from sip reply when using sl_send_reply? I wanted to generate 200 ok, with SDP payload. I appended headers like below. The packet seems ok except there is extra "Content-Length:0", which is causing problems. Any workarounds? The packet being generated is: Note the extra content-length: 0 at the end.

Santosh, Looks like you didn't include the mohdir information (see http://kamailio.org/docs/modules/4.4.x/modules/mohqueue.html#dir.parms) or there are no files in that directory.

Kamailio SIP Proxy solution
by Hai Bui Duc Ha 25 Apr '17

25 Apr '17

Hi all, I'm researching the solution on Kamilio like SIP forward message: - At the moment, the customer has server IP PBX and their clients. - Then, the client just point the SIP Porxy configure to Kamailio. After that, Kamailio will forward to IP PBX and send the event to another server. - Everything will be not changed for customer site. I found the link do the similar thing but it still authenticate on Kamailio: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb… Do you have any advice ?

Video recording with RTPENGINE
by Alberto Llamas 24 Apr '17

24 Apr '17

Hi guys, Any of you have experience using the '*start_recording()*' function of the RTPENGINE in a WebRTC scenario?. At this point, I am able to record the stream but I am not able to play them. The output is a .pcap file in a raw format. I have tried the conversion: raw -> H264 -> mp4/avi (with different tools: videosnarf, x264, ffmepg) and not luck. Do you know the right way to convert those stream in raw format?. Any hint will be appreciated. Regards,

MSRP Connection is not working
by Jegadeesan 24 Apr '17

24 Apr '17

Hi , I'm very new to Kamailio application and trying to setup the test environment for Android RCS client (https://github.com/android-rcs/rcsjta). Parallelly we have deployed the Kamailio on ECS2 and able to make a call/text using any other sip clients. Apparently, we had enabled the MSRP modules over TCP and tried to test with Android RCS. But getting stuck at the connecting screen. Although we could see SIP exchange logs between two clients. Can anyone help me in fixing this issue? -- Jegadeesan M

Kamailio not forwarding call
by Gonzalo Gasca Meza 22 Apr '17

22 Apr '17

Hi all, I worked in an prototype recently where I *had* the following setup working. Kamailio is using Postgres to forward the call to Twilio domain. *Topology:* SIP client (tls) > (SIP Provider) > (tls) Kamailio (udp) > Twilio > IVR Right now when I call from SIP Client to IVR, call is not forwarded. Nothing has changed on Kamailio side. *Troubleshooting:* a) *SIP client (tls) > (SIP Provider) > (tls) Kamailio (udp) > Twilio > IVR [Fails]* - Case described above. b) *Call from PSTN > (SIP Provider) > (tls) Kamailio (udp) > Twilio > IVR [Works]* I debug and call arrives to Kamailio but is not being forwarded to Twilio. This used to work before. When call works Kamailio seems to find remote domain, when fails we just sent a *502 Bad Gateway* message Twilio does not support DNS SRV records, just A host resolution. *Logs* While looking at debugs I found that this DNS logs: Pastebin below: *Call fails <https://pastebin.com/ttkK1Kkd> * Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (_sip._ udp.parzee.sip.twilio.com(31), 33), h=816 Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [resolve.c:741]: get_record(): lookup(_sip._ udp.parzee.sip.twilio.com, 33) failed Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:864]: dns_cache_mk_bad_entry(): (_sip._ udp.parzee.sip.twilio.com, 33, 60, 1) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:798]: dns_cache_add(): adding _sip._ udp.parzee.sip.twilio.com(31) 33 (flags=1) at 816 Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (parzee.sip.twilio.com(21), 1), h=267 Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [resolve.c:937]: get_record(): skipping 0 NS (p=0xa1d2e7, end=0xa1d2e7) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [resolve.c:952]: get_record(): parsing 0 ARs (p=0xa1d2e7, end=0xa1d2e7) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:1741]: dns_get_related(): (0x7f1b5c227920 ( parzee.sip.twilio.com, 1), 1, *(nil)) (0) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:840]: dns_cache_add_unsafe(): adding parzee.sip.twilio.com(21) 1 (flags=0) at 267 *Call works <https://pastebin.com/AkWsvFVA>* Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (_sip._ udp.parzee.sip.twilio.com(31), 33), h=816 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [resolve.c:741]: get_record(): lookup(_sip._ udp.parzee.sip.twilio.com, 33) failed Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:864]: dns_cache_mk_bad_entry(): (_sip._ udp.parzee.sip.twilio.com, 33, 60, 1) Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:798]: dns_cache_add(): adding _sip._ udp.parzee.sip.twilio.com(31) 33 (flags=1) at 816 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (parzee.sip.twilio.com(21), 1), h=267 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [msg_translator.c:2876]: create_via_hf(): id added: <;i=7>, rcv proto=3 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [msg_translator.c:158]: check_via_address(): (54.172.60.0, 54.172.60.0, 0) Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: tm [t_funcs.c:368]: t_relay_to(): SER: new transaction fwd'ed Thank you!

Kamailio rtpengine sdp
by gerry kernan 21 Apr '17

21 Apr '17

Hi Thanks in advance if anyone can point me in the correct direction . I have kamailio running in front of some asterisk VM's. SIP endpoint register to their asterisk PBX via Kamailio dispatcher module. I'm running rtpengine with a Wan and private interface to bridge audio stream between these endpoints on the WAN to asterisk PBX running on LAN IP behind Kamailio. Calls from ext to ext work fine audio both directions , calls outbound to PSTN via SIP trunk to SIP provider via trunk on asterisk work fine audio both directions. But incoming calls via SIP provider I only get audio on stream from asterisk registered ext to external caller , no audio from external caller to the asterisk ext. I reckon I have something wrong in my Kamailio.cfg . if I register an ext direct to asterisk I get audio both ways on incoming calls. And rtp logs from rtpenegine show it as trying to send the rtp to the private address of the sip endpoint rather that its WAN address. I think my mistake in somewhere in the cfg below. Do I need to handle invites from the backend asterisk servers different that invites from sip endpoints?

NOTIFY request from PCSCF is on TCP transport rather than UDP
by Haggerty, Paul (phaggert) 21 Apr '17

21 Apr '17

Hello, I've got an IMS client which uses UDP for transport. Our application server is also using UDP. We are using a Kamailio IMS Core. The client REGISTERS with UDP and also does a SUBSCRIBE. Our application server responds with a NOTIFY to the client. Looking at the trace. The messages between the PCSCF and SCSCF are TCP. The REGISTER and SUBSCRIBE responses to the client from the PCSCF are UDP (which I would expect). However, when the PCSCF get the NOTIFY is tries to open a TCP connection to the Client. (I assume to send a NOTIFY). Any ideas of what is happening here? I'm fairly new to the Kamailio IMS. I am more familiar with the Open IMS Core. (which is not having this issue). Thanks, Paul

Kamailio World 2017 - grants for students and underrepresented people
by Daniel-Constantin Mierla 21 Apr '17

21 Apr '17

Hello, with a bit of delay, given that had to accommodate and accept some requests from the last year queue, I am glad to announces that we can offer two more seats at Kamailio World Conference, May 8-10, 2017, in Berlin. Therefore we are continuing the program from last years, based on the roots and the tight relation of Kamailio project with the academic environment, the eligible people being students enrolled in universities or research institutes (both bachelor and PhD programs qualify) as well as people from underrepresented groups. If you think you are eligible and want to participate, email me directly (miconda(a)gmail.com) or to registration(a)kamailio.org . Participation to all the content of the event (workshops, conference and social event) is free, but you will have to take care of expenses for traveling and accommodation. Write a short description about your interest in real time communications and, when it is the case what is the university or the research institute you are affiliate to. Also, if you are not a student, but you are in touch with some or have access to students forums/mailing lists, it will be very appreciated if you forward these details. Time is short, we already received few requests based on my remark in a message sent out few weeks ago, therefore in a matter of days we will do the selection, so you have to hurry up a bit. More information about Kamailio World is available on the web site: - http://www.kamailioworld.com Many thanks to the event sponsors that allowed to continue this program, respectively: FhG Fokus, Asipto, Flowroute, Telnyx, Sipwise, Sipgate, Simwood, Obihai, NG-Voice, Evariste Systems, Digium, VoiceTel, Pascom and Core Network Dynamics.

Hi, I wanted to make an http_async_query in event_route[dialog:start] after the call the confirmed. I see that flow does not even get to making "async_send_query". Perhaps it is failing at the first line "if (msg==null)" in w_http_async_post as I don't see any other error messages from the module. I can confirm that my setup and api server are fine as other calls I make from request_route and event_route[dialog:end] are working. I am attaching herewith my config files and Kamailio.log file. Relevant prob spot is below- Apr 20 17:37:17 devsip00 /sbin/kamailio[6286]: {2 3094 INVITE d9695149ce484811ab98ca41a4e8c694} INFO: <script>: Translation: TextBroker - Making CallAnswered for d9695149ce484811ab98ca41a4e8c694 If you notice we don't see any further progress of this call in http_async_client module. Can someone suggest what I am missing/where else can I know for sure dialog is confirmed and make this call.

Kamailio 5.0 doesn't forward Authorization (Digest username) to Asterisk
by gh 21 Apr '17

21 Apr '17

Hi Marko, i work on the same scenario. It should work with: if(uac_reg_request_to("$fU", 0)) { xlog("L_NOTICE", "Found remote user [$rU] on [$rd] via [$du]"); t_on_failure("REMOTE_AUTH"); t_relay(); } But in my case xlog() currently does not print out the variables, so i am not able to debug:-( Can you try this code and tell me if xlog() works for you? Best regards Georg

Planning next IRC devel meeting - Apr 20, 2017
by Daniel-Constantin Mierla 20 Apr '17

20 Apr '17

Hello, probably it is the time to have another IRC devel meeting to discuss the plans for the project and the roadmap to next major release, v5.1. First proposed date would be Apr 20, with secondary options for Apr 24 or 25, but other dates can be taken in consideration if more convenient for a consistent group of developers. I created the wiki page for it at: * https://www.kamailio.org/wiki/devel/irc-meetings/2017a Feel free to add there the subjects you want to discuss, I also have several other topics to add. It would be good to list yourself if you are going to participate (or want to participate) in a specific day in order to see who are we relying on being present. Cheers, Daniel -- Daniel-Constantin Mierla www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - May 22-24 (USA) - www.asipto.com Kamailio World Conference - May 8-10, 2017 - www.kamailioworld.com

Reply to Incoming SIP Options Pings from Kamailio
by SIP Tech 20 Apr '17

20 Apr '17

Hello, I have a simple Kamailio server built that acts as a stateless load balancer for incoming SIP calls. All kamailio does here is receive the incoming call and route it round robin to a Freeswitch machine behind it. All configuration in Kamailio is done in local config files including the use of dispatcher.list. I have an external 3rd party partner sending my Kamailio machine SIP options pings. Because my Kamailio sends all incoming calls stateless to a FS machine behind it (round robin) the FS machines behind Kamailio get the incoming ping requests and generate the 200 OK reply back to kamailio. I would like the 3rd party to get a 200 OK for pings directly from my Kamailio and not from freeswitch behing it. I have the need to scale FS machines on the fly so I don't want FS machines to be responsible for the sip options ping replies. I want Kamailio itself to reply with a static 200 OK to incoming ping requests. I have looked into nathelper and siputils options_reply to see if I could get a simple static config to handle this 200 OK directly from Kamailio. I cant get it to fully work as the incoming sip pings still hit freeswitch. How can I configure this in the kamailio.cfg to get kamailio itself to reply with a 200 OK to SIP Options Pings and NOT forward the ping request to freeswitch? Here is my current simple stateless LB config in kamailio that works great for what it is and for what I need for loadbalancing incoming call requests. route{ if ( !mf_process_maxfwd_header("10") ) { sl_send_reply("483","To Many Hops"); drop(); }; ds_select_dst("1", "4"); forward(); #stateless forward # t_relay(); #stateful relay } Here is a sample of what the incoming pings look like that hit Kamailio. U 2017/04/19 21:21:00.89 192.168.168.168:5060 -> 172.31.31.31:5060 OPTIONS sip:172.31.31.31:5060 SIP/2.0. Via: SIP/2.0/UDP 192.168.168.168:5060;branch=z9hG. Call-ID: 536f9b34c(a)192.168.168.168. To: sip:ping@172.31.31.31. From: <sip:ping@192.168.168.168>;tag=2b769f. Max-Forwards: 70. CSeq: 91160 OPTIONS. Route: <sip:172.31.31.31:5060;lr>. Using the above info what would a route look like in kamailio.cfg for this? What specific modules need to be installed/enabled to make your suggested route functional? Thanks guys

How to print out all variables in case we reach this line?
by gh 19 Apr '17

19 Apr '17

If i call a mobil number: t: <sip:+4917625251111@sip.heissa.de>. i get 404, but would expect rewrite to carrier route: sip:+4917625251111@sip.nexxtmobile.de Is there a way to print out all variables at this moment? ########################################################### if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server route(RELAY); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404", "Not here"); #How to print out all variables in case we reach this line??? exit; ###########################################################

to tag length
by Diego Nadares 19 Apr '17

19 Apr '17

Hi guys, Does exist a max length for to tag? Because I'm saving dialogs in mysql and yesterday a message had a to tag greater than varchar 64. db_mysql_submit_query(): driver error on query: Data too long for column 'to_tag' at row 1 The length of the to tag was 65 (SDu81l799-7f56830f3e18-100007f-13c4-6009-73d4c9b-10f3d231-73d4c9b) Cheers, Diego

Hello, good moorning. I have a Kamailio 4.0.2 with debian 7.0 and this days I'm configuring dual stack ipv4 & ipv6 in all servers. I have configured ipv6 today in my kamailio server and when I make a /etc/init.d/networking restart, everything seems to be working fine (ipv6 works), but when I make a "kamctl mi dlg_list", the next error appears: root@sipproxy:/etc/network# kamctl mi dlg_list ERROR: Error opening Kamailio's FIFO /tmp/kamailio_fifo ERROR: Make sure you have the line 'modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo")' in your config ERROR: and also have loaded the mi_fifo module. Disable ipv6 and now works fine. restart kamailio service is "complicated" to test anythink. Any ideas ? thanks -------------------------------- Ángel Elena Medina _o) craem(a)craem.net / \\ http://blog.craem.net _(___V @craem_ --------------------------------

too long mysql table key
by Juha Heinanen 15 Apr '17

15 Apr '17

I tried to install kamailio mysql db on Debian Stretch. Create of domain_attrs table failed with this kind of error message: ERROR 1071 (42000) at line 26: Specified key was too long; max key length is 767 bytes domain-create.sql contains this: CREATE TABLE `domain_attrs` ( `id` INT(10) UNSIGNED AUTO_INCREMENT PRIMARY KEY NOT NULL, `did` VARCHAR(64) NOT NULL, `name` VARCHAR(32) NOT NULL, `type` INT UNSIGNED NOT NULL, `value` VARCHAR(255) NOT NULL, `last_modified` DATETIME DEFAULT '2000-01-01 00:00:01' NOT NULL, CONSTRAINT domain_attrs_idx UNIQUE (`did`, `name`, `value`) ); Looks like default charset is something (e.g. utf8), where one char takes more than 1 byte and 767 limit is exceeded. Any suggestions on how to solve this? -- Juha

RFC: kamailio-announce mailing list
by Daniel-Constantin Mierla 14 Apr '17

14 Apr '17

Hello, for a while in the past (like 2008-2011) the kamailio-announce(a)lists.kamailio.org mailing list was used for very sporadic announcements: - https://lists.kamailio.org/cgi-bin/mailman/listinfo/kamailio-announce It was intended to be used to announce only relevant news about the project (releases, major events, etc.), which most of them go also on sr-users, but targeting community members than which prefer to avoid high traffic, which is specific for the usual discussions here. Also, for people in sr-users, can be a place to spot easier the major announcements. Because we migrated back to lists.kamailio.org domain, this list is now presented on the page of mailman index: - https://lists.kamailio.org/cgi-bin/mailman/listinfo I just marked it as 'inactive', but I am wondering if it should be revived somehow (as some people wanted to have a place where to inform about relevant security issues, etc...) or be closed (removed/made private). Even it was not used/promoted for more than 5 years, I noticed that it has over 200 subscribers, therefore it seems to be enough people interested in it. Reply here if you consider it to be useful and eventually give some suggestions for what kind of announcements should be used. Note that there is already business(a)lists.kamailio.org (with larger subscriber base) for business related announcement or discussions.

Using advertised_addres doesn't update the RR header
by Mridul B 13 Apr '17

13 Apr '17

Hi, Using *advertised_address *core parameter in the kamailio script doesn't update the address mentioned in the Record-Route header. We see this problem in the 200 OK message (of the INVITE msg), where the Record-Route header sent by the Kamailio contains socket address. We're using kamailio 4.4.5 (x86_64/linux) 239f3c Can you please tell if this core parameter is effective for changing the RR header ? Thanks Best regards, *MRIDUL*

Rtpengine module. rtcp-mux-demux option does not work.
by Denys Pozniak 13 Apr '17

13 Apr '17

Hello, All! We are using Kamailio as Webrtc to SIP proxy. Clinet's Chrome browser needs to have rtcp-mux option to work correct, so we are adding it in RTPENGINE->WS direction as: rtpengine_manage("trust-address replace-origin replace-session-connection *rtcp-mux-offer rtcp-mux-accept* ICE=force RTP/SAVPF"); Also we need to remove it in RTPENGINE->PSTN direction, we are trying to do it like this: rtpengine_manage("trust-address replace-origin replace-session-connection * rtcp-mux-demux* ICE=remove RTP/AVP"); But it does not work for us and a=rtcp-mux option in SDP goes to the SIP provider. Please help us to solve this! BR, Denys PS. Versions: Kamailio 4.4.5, rtpengine 5.2.1.0

Hello, just to let everyone know that I invited Mikko Lehto into the developer group on Kamailio gihub project. He has made a lot of good pull requests over the time, specially to documentation and unit tests that could have been just committed directly without delay on waiting for a review, saving also time from the other developers. Taking time to express my thanks for all his contributions so far and reviving those unit tests, and I am looking forward to future collaboration!

issue with sip path support between asterisk and kamailio
by gerry kernan 12 Apr '17

12 Apr '17

Hi Thanks in advanced if anyone can help me on this. I have kamailio -4.2.3-1.1 running in front of asterisk 13.13.1. I'm using Path support with asterisk so that I can forward Sip requests via kamailio to the asterisk server running on a LAN IP. Kamailio is configured with a WAN and LAN IP. All works well I can register a sip endpoint to the asterisk server via kamailio and make an receive calls, SIP OPTIONs from the asterisk server are received and relayed by kamailio to endpoints. But I'm having issues when a call is hung up asterisk appears to be trying to send the BYE via its own IP address rather that the IP of the LAN interface on the kamailio server. Should I be looking at the issue being on asterisk as it is not sending the BYE via correct IP?

Kamailio 5.0 doesn't forward Authorization (Digest username) to Asterisk
by Marko Tirs 11 Apr '17

11 Apr '17

Hello all, I am trying to use Kamailio 5.0 with Asterisk (separate IP addresses, both port 5060), but Asterisk doesn't register the SIP clients which comes through Kamailio.If I register the same user directly to the Asterisk then it works! 1st REGISTER is also without Authorization (Digest name) but in the 2nd REGISTER it exists and registration goes OK.

Hello, all the mailing lists related to the Kamailio project are using now lists.kamailio.org as primary domain, including sr-dev and sr-users. >From now on, the emails should be addressed to: - sr-dev(a)lists.kamailio.org - sr-users(a)lists.kamailio.org The previous domain (lists.sip-router.org) should still work, so existing discussions can go on as usual. If anyone is encountering any problems or notices some information on kamailio.org that needs to be updated, do not hesitate to reply here or contact me. In addition, URLs should use now https, browsing the archive with plain http is redirected to https urls.

Disable DNS
by Diego Nadares 11 Apr '17

11 Apr '17

Hi Guys, Is it possible to disable using of dns in kamailio? The thing is that not all INVITES that arrives to the proxy comes with ip 172.16.205.25/PUB_IP in the ruri. Some gateways sends a string in ruri -> @myproxysip and others sends @other.domain.com Request-Line: INVITE sip:1111111@myproxysip:5060;user=phone SIP/2.0 Request-Line: INVITE sip:1111111@other.domain.com:5060;user=phone SIP/2.0 Sometimes, myproxysip is from a public ip and sometimes is from a private ip. So, it's difficult to know to which of kamailio's interfaces (pub or priv) is. ERROR: <core> [resolve.c:1694]: sip_hostport2su(): could not resolve hostn ame. Reconfigure those gw it's not possible. There are a lot of them and a lot of people that won't like that idea. Is possible to disable it? or What do you recommend me to do? Maybe using /etc/hosts? Any suggestion will be very appreciated. Diego.

Use of variables for force_send_socket
by Jöran Vinzens 11 Apr '17

11 Apr '17

Hi all, i try to re-arrange my config and i try to use a variable declared in modparam pv such like: modparam("pv", "varset", "externalip=s:1.2.3.4") and use it as: force_send_socket($var(externalip)); unfortunately the kamailio does not start with this configuration and telling me bad config file like: line 109, column 36: bad argument, [proto:]host[:port] expected it seems the force_send_socket is not able to get variable. Is there any other way to have static content defined and put across the config? Reason for the question is the possibility to use ansible as deployment tool. I set all the variables i need in a separate file and include it. This file contains the entire modconfig and global vars section to adapt this part to every single machine individually. This does not work if i need to put "constant" variables on different places in my config. If anybody has ever made this, could you please help me, or give any suggestions? Many thanks!

Hello, be aware that today I plan to do some maintenance on the mailing lists server, including the shifting to the lists.kamailio.org as primary domain. I expect not to have any relevant downtime, but one never knows. Maybe the archive won't be available for short time due to changes needs to be done to the web server after mailing lists server is upgraded. I will sent another notification when everything is finished.

Authentication on Kamailio with MySQL
by Nicolas Pace 10 Apr '17

10 Apr '17

Hi everyone, I'm having some trouble setting up a simple Kamailio installation with user authentication. I've installed a kamailio (4.3.4) base install on an ubuntu server 16.04 (x86/64) on virtualbox, and added this lines at the beginning of the file: ``` #!KAMAILIO #! define WITH_MYSQL #! define WITH_AUTH #! define WITH_USRLOCDB ``` Also configured the db name, host, user and pass for RO and RW and run `kamdbctl create`. Everything I do was following this tutorial: http://www.kamailio.org/wiki/tutorials/getting-started/main Based on what the tutorial says, I should have a server that only allows users that have been authenticated against the DB. The thing is that now Kamailio allows me to access, no matter what credentials I gave him (replies 200 OK to my REGISTER requests, and whows the user on the `kamctl monitor` view). I've added to this gist: * My current kamailio config * the kamailio grepped syslog * the pjsua output from when I register with an unexistent user https://gist.github.com/nicopace/9d44bf813fe309df69ff4cd0affe8324 I've already checked out some of the wiki documentation, namely: * http://www.kamailio.org/wiki/tutorials/auth/auth_db * http://www.kamailio.org/wiki/tutorials/getting-started/main Am I missing something? Thanks

Introduction
by Nicolas Pace 10 Apr '17

10 Apr '17

Hi Everyone! I just wanted to introduce myself, before blasting the list with questions (just kidding!). My name is Nicolás Pace, I'm a Community Networks advocate from Argentina. I'm working on a community project for Rhizomatica [0], which is an amazing organization that promotes Community Cellular Networks for underserved communities in Latin America (mainly mexican's first nations but also in Nicaragua, Colombia nad Brazil). We are working on a mobile app to connect the Community Cellular Networks (that uses 2G Cellular Networks) with the rest of the world via SIP, and we are considering using Kamailio for this. The project has been using FreeSwitch for some time and now we are thinking about using Kamailio on the cloud side, and intengrate them via SIP. On a not so distant future, if the Kamailio experience goes well, we are thinking on moving everything to Kamailio, as it seems to be much more simple and effective. For now we expect to do a prototype to connect this communities with their relatives via SMS (on the Cellular side) with SIP SIMPLE Messages (on the 'cloud' side). Awesome to meet you all, and hope to be collaborating with this community! Regards, [0] https://www.rhizomatica.org/

INFO: Shifting mailing lists to kamailio.org domain
by Daniel-Constantin Mierla 10 Apr '17

10 Apr '17

Hello, I think it is time to migrate the mailing lists under kamailio.org domain, respectively use lists.kamailio.org. The lists.sip-router.org will still work, but lists.kamailio.org is intended to become the primary domain for mailing lists. The sip-router.org was the quick solution for integrating Kamailio and SER in one project back in 2008, when kamailio.org and iptel.org still needed to be operated for a while as independent projects. For few years now, Kamailio is the only project name that is used out there and it will make operating everything a bit smoother, more coherent and also avoid eventual confusions for people new into the project. As a matter of fact, we even had a small incident few weeks ago -- due to split management of sip-router.org and DNS registration expire notifications going to an email address on a different server than kamailio.org, the domain was expired for few hours (although it was kept on hold by registrar) and mailing lists started to be unavailable. Fortunately that was discovered and fixed in time. The names will stay the same sr-users and sr-dev, just primary domain will be using kamailio.org (which should 'hopefully' work even now, as this email was addressed with mixed sr-dev(a)lists.sip-router.org and sr-users(a)lists.kamailio.org). If anyone has different opinions or suggestions, let's discuss them!

Transaction Lookup Failing
by Colin Morelli 10 Apr '17

10 Apr '17

Hey all, Trying to debug an issue with canceling an invite. I have two different types of clients. On one client, canceling an invite works correctly. With the other client, it t_check_trans fails. Both clients show the same request/responses: On Client A: -> INVITE <- 183 -> PRACK <- 200 -> UPDATE (from successful STUN binding) <- 200 -> CANCEL <- 200 On Client B: -> INVITE <- 183 -> PRACK <- 200 -> UPDATE (from successful STUN binding) <- 200 -> CANCEL <- 481 (this is sent from my kamailio script when t_check_trans fails) I can't see much that's different between the leading requests/responses of each. They seem to be virtually identical (with the exception of IP addresses and tag values, of course). This makes sense, since they're both based on PJSIP (albeit different versions of PJSIP, but not off by much) Is there anything in particular I should be looking out for that might be obvious? I could provide more detailed logs and traces if required. Best, Colin

Carrier Route Module
by Tyler Preder 10 Apr '17

10 Apr '17

I am new to Kamailio. I've got the Carrier Route module up and running, but I'd like to match on scan_prefix length and not just the scan_prefix digits. Stated a little differently, I would like to define the scan_prefix and how many digits to expect after the scan_prefix. I am hoping that wildcards are supported in the scan_prefix field or is there another way to do this? Thanks, Tyler

RTPengine + kernel module long call RTP drops
by Anthony Joseph Messina 05 Apr '17

05 Apr '17

Recently, I've had to be on a lot of long conference calls and have noticed that after about 18-22 minutes, the audio on the call drops out. There are no errors logged from Asterisk, Kamailio, or RTPengine. The signalling portion of the call is unaffected and continues as normal. My setup is as follows asterisk-14.3.0-7.gita047b25.fc25.x86_64 (14 branch) kamailio-5.0.0-5.git2608015.fc25.x86_64 (5.0 branch) kernel-4.10.8-200.fc25.x86_64 (stable Fedora kernel) rtpengine-5.1.1.1-9.git27af349.fc25.x86_64 (master branch) Yealink or Zoiper softphones Calls are originated as follows using TLS & SRTP Yealink/Zoiper -> Kamailio/RTPengine+kernel -> Asterisk/DAHDI/PSTN Related IPtables output below (generated by firewalld) ~]# iptables -S |grep INPUT -P INPUT ACCEPT -N INPUT_ZONES -N INPUT_ZONES_SOURCE -N INPUT_direct -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -j INPUT_direct -A INPUT -j INPUT_ZONES_SOURCE -A INPUT -j INPUT_ZONES -A INPUT -m conntrack --ctstate INVALID -j DROP -A INPUT -j REJECT --reject-with icmp-host-prohibited -A INPUT_direct -p udp -m udp --dport 30000:40000 -j RTPENGINE --id 0 -A INPUT_ZONES_SOURCE -m set --match-set mss4 src -g IN_mss -A INPUT_ZONES -g IN_public -A IN_public -j IN_public_allow -A IN_public_allow -p udp -m udp --dport 30000:40000 -m conntrack \ --ctstate NEW -j ACCEPT I saw https://github.com/sipwise/rtpengine/issues/102 and https://github.com/sipwise/rtpengine/issues/108, but do not seem to have any issues (that I know of) with the SRTP, though the latter ticket references "call that would last longer than 20 minutes". Can you share suggestions for looking into the cause of the audio drops, especially as nothing appears in the logs?

Replacing a message body received with a subsequent message sending out of kamailio
by narayan panigrahi 05 Apr '17

05 Apr '17

Hi All, I have a architecture of pjsip,kamailio,freeswitch and one external server. When kamailio is receiving "407"-proxy authentication required from the external server it sends to freeswitch and received "407" from freeswitch.But when replying back to kamailio the freeswitch is adding some extra headers in that "407". Now I need to send the message from kamailio to pjsip the same thing received from external server.So I need to replace the message received from external server with the message received from freeswitch at kamailio. I am using redis db to store the message.Can anybody help me how to configure the kamailio so that it will replace the message with freeswitch message and send the original message received before i.e. from external server. Any suggestion will be highly appreciated. Thanks, Narayan +91-9035438928

Kamailio 5.0.0 KEMI Lua event routes
by José Seabra 05 Apr '17

05 Apr '17

Hi all, I'm starting using kamailio 5 and was trying to convert my actual routing scripts to new KEMI interface using Lua. In my old script i'm using event routes for the evapi, dialog and dispatcher modules, so i was wondering how can i use it on KEMI. It exports some special Lua function to the KEMI framework? Can anyone give an example please. Many thanks José Seabra

Hello all, I’m newbie to Kamailio and I’m having problem with installation. I tried to install Kamailio through '/usr/local/sbin/kamdbctl create’ but it showed error that database engine not specified. When I checked the kamctlrc file, the DBENGINE was already MYSQL. (DBENGINE=MYSQL) What am I missing here?? Cheers, Hyoung Kyoon Roh

Problems with avp_db_load
by Kevin Bushong 04 Apr '17

04 Apr '17

I am using the avpops module to read from a mysql database to look for CFWD information for the call. When a call is placed, it appears the command avp_db_load attempts to read the file but all values come back as NULL. There are no messages in the log and of course the call does not process correctly. We are using a config that is exactly the same on a 4.3.4 version of kamailio using cento 6.7, with a local version of mysql Ver 14.14 Distrib 5.1.73, that works perfectly. When moving the code to kamailio 4.4.4 on Debian 8, Jessie, mysql Ver 14.14 Distrib 5.5.53 the avp_db_load returns no information. Here is the snippet of the code we are using. Since I am not used to troubleshooting kamailio, please let me know what other information you need. Thanks, Kevin Code snippet: #!ifdef WITH_CFWD xlog ("$TF Call to $rU made it into WITH_CFWD in route[LOCATION] block\n"); # Call forwarding is enabled, so lets do a lookup to pull all AVP's for possible call forwarding types/destinations # Below line should load all AVP's into memory from DB for the username portion of the TO: field from table usr_preferences xlog("script should load from DB usr_preferences next"); avp_db_load("$tU","s/usr_preferences"); # This line i simple want to print to log when the avp load is complete and what the values are (for debug purposes only and should typically be commented out) xlog("DB load should be complete"); xlog("SCRIPT: $TF Call Forwarding Unconditional set to $avp(Unconditional)\n"); xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n"); xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n"); avp_print(); # Check to see if the AVP's are set and if so put them in log for logging purposes if(is_avp_set("$avp(Unconditional)")) xlog("SCRIPT: $TF Call Forwarding Unconditional set to $avp(Unconditional)\n"); if(is_avp_set("$avp(NoAnswer)")) xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n"); if(is_avp_set("$avp(Busy)")) xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n"); t_set_fr(16000, 15000); # set fr invite timeout to 16s and no response at all to 15s to meet the specs for call fowarding no answer ringtime # If Call fowarding Unconditional is set, we need to change the dialed number and sent it off to the original users trunk from subscriber table # Check to see if unconditional is set if(is_avp_set("$avp(Unconditional)")) # Shove this call into route [PSTN_CFWD] Block route("PSTN_CFWD"); Here is the syslog for the same snippet: 09:29 2017 Call to 15703771055 made it into WITH_CFWD in route[LOCATION] block Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: script should load from DB usr_preferences next Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: DB load should be complete Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding Unconditional set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding NoAnswer set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding Busy set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1473]: ops_print_avp(): p=0x7f440ed86f90, flags=0x0113 Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1477]: ops_print_avp(): #011#011#011name=<direction> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1485]: ops_print_avp(): #011#011#011val_str=<INCOMING / 8>

Why these 2 items in the same entry for a htable
by Ginhoux, Patrick 04 Apr '17

Hi, While working on the project to migrate my kamailio.cfg script from kamailio 3.3.1 to 5.0.x, I discovered that in there are 2 items in the same htable. Below the figure that illustrate this case : 1) Content of the MBXRANGE table : mysql> select * from mbxrange; +-----+-------------+-------------------------------------------------+----- -------+----------+ | id | key_name | key_value | value_type | key_type | +-----+-------------+-------------------------------------------------+----- -------+----------+ | 0 | VERSION | 120104-173400 | 0 | 0 | | 101 | 1 | min=0100000000;max=0199999999;node=OPMVTS1VSE02 | 0 | 0 | | 102 | 2 | min=0200000000;max=0299999999;node=OPMVTS1VSE02 | 0 | 0 | | 103 | 3 | min=0300000000;max=0399999999;node=OPMVTS1VSE02 | 0 | 0 | | 104 | 4 | min=0400000000;max=0499999999;node=OPMVTS1VSE02 | 0 | 0 | | 105 | 5 | min=0500000000;max=0599999999;node=OPMVTS1VSE02 | 0 | 0 | | 106 | 6 | min=0600000000;max=0699999999;node=OPMVTS1VSE02 | 0 | 0 | | 107 | 7 | min=0700000000;max=0799999999;node=OPMVTS1VSE02 | 0 | 0 | | 108 | 8 | min=0800000000;max=0899999999;node=OPMVTS1VSE02 | 0 | 0 | | 109 | 9 | min=0900000000;max=0999999999;node=OPMVTS1VSE02 | 0 | 0 | | 199 | maxmbxrange | 9 | 0 | 0 | +-----+-------------+-------------------------------------------------+----- -------+----------+ 11 rows in set (0.00 sec) 2) modparam instruction used in my kamailio.cfg script: modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") 3) Result of < kamctl fifo sht_dump mbxrangeHash > command with kamailio version 3.3.x: [root@op52is4router1 ~]# kamctl fifo sht_dump mbxrangeHash Entry:: 0 6:: min=0600000000;max=0699999999;node=OPMVTS1VSE02 Entry:: 1 7:: min=0700000000;max=0799999999;node=OPMVTS1VSE02 Entry:: 2 4:: min=0400000000;max=0499999999;node=OPMVTS1VSE02 Entry:: 3 5:: min=0500000000;max=0599999999;node=OPMVTS1VSE02 Entry:: 4 2:: min=0200000000;max=0299999999;node=OPMVTS1VSE02 Entry:: 5 3:: min=0300000000;max=0399999999;node=OPMVTS1VSE02 VERSION:: 120104-173400 Entry:: 6 maxmbxrange:: 9 Entry:: 7 1:: min=0100000000;max=0199999999;node=OPMVTS1VSE02 Entry:: 14 9:: min=0900000000;max=0999999999;node=OPMVTS1VSE02 Entry:: 15 8:: min=0800000000;max=0899999999;node=OPMVTS1VSE02 Result of < kamcmd htable.dump mbxrangeHash > command with kamailio version 5.0.x : [root@vm-vse02-siprouter1 ~]# kamcmd htable.dump mbxrangeHash { entry: 0 size: 1 slot: { item: { name: 6 value: min=0600000000;max=0699999999;node=OPMMMS1VSE02 type: str } } } { entry: 1 size: 1 slot: { item: { name: 7 value: min=0700000000;max=0799999999;node=OPMMMS1VSE02 type: str } } } { entry: 2 size: 1 slot: { item: { name: 4 value: min=0400000000;max=0499999999;node=OPMMMS1VSE02 type: str } } } { entry: 3 size: 1 slot: { item: { name: 5 value: min=0500000000;max=0599999999;node=OPMMMS1VSE02 type: str } } } { entry: 4 size: 1 slot: { item: { name: 2 value: min=0200000000;max=0299999999;node=OPMMMS1VSE02 type: str } } } { entry: 5 size: 2 slot: { item: { name: 3 value: min=0300000000;max=0399999999;node=OPMMMS1VSE02 type: str } item: { name: VERSION value: 120104-173400 type: str } } } { entry: 6 size: 1 slot: { item: { name: maxmbxrange value: 9 type: str } } } { entry: 7 size: 1 slot: { item: { name: 1 value: min=0100000000;max=0199999999;node=OPMMMS1VSE02 type: str } } } { entry: 14 size: 1 slot: { item: { name: 9 value: min=0900000000;max=0999999999;node=OPMMMS1VSE02 type: str } } } { entry: 15 size: 1 slot: { item: { name: 8 value: min=0800000000;max=0899999999;node=OPMMMS1VSE02 type: str } } } So, I can see : - The entry number is not incremental 1 by 1 ; there are entry #1 to #7, then #14 and #15 (all have size=1) - For the entry #5, its size is of 2 and it contains 2 items I don't say here that this is a problem, but the way the htable is loaded seems strange to me. So if there people who can explain me if what I see is normal or not, and how the htable load process works, I would appreciate. Thanks in advance. Cordialement Patrick GINHOUX

Via header with i attribute
by DanB 04 Apr '17

04 Apr '17

Hey Guys, Any of you know which module is adding the "i" attribute and maybe if it can be removed safely? The reason would be for some Avaya PBXes discarding the Via completely due to this attribute. Sample header: """ Via: SIP/2.0/UDP 1.2.3.4;branch=z9hG4bKf0d6.72eca17f202d1e73a1f519dbecf7d6a6.0;i=8f1. """ Many thanks, DanB

Re: [SR-Users] ht_db_load_table(): key type must be string (type=6)
by Ginhoux, Patrick 04 Apr '17

Hi, A second update for people who started to look at this issue. I have identified the real cause of the problem by looking more in the kamailio log with the debug traces. I discover that it is related to the load of the properties table in the htable. I have the following entries in my mysql db : +-------+----------------+---------------------------------------------------------+------------+----------+ | id | key_name | key_value | value_type | key_type | +-------+----------------+---------------------------------------------------------+------------+----------+ | 0 | VERSION | 120104-1734 | 0 | 0 | | 1 | mmm-retry | 408=Y;502=Y;503=Y | 0 | 0 | | 2 | mgcf-retry | 408=Y;502=Y;503=Y | 0 | 0 | | 3 | max-mmm-retry | 2 | 0 | 0 | | 4 | max-mgcf-retry | 2 | 0 | 0 | | 5 | target-uri | mgcf=10.10.10.10;mmm-legacy=20.20.20.10;mmm=20.20.20.20 | 0 | 0 | | 6 | pike-status | 503 Service Overload | 0 | 0 | | 7 | mgcf-path | 99 | 0 | 0 | | 16 | mmm-nodeid | OPMMMS1VSE01=1;OPMMMS1VSE02=2 | 0 | 0 | | 17 | mmm-node-path | 1=1;2=2 | 0 | 0 | +-------+----------------+---------------------------------------------------------+------------+----------+ In the kamailio.cfg, the << modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") >> command causes the load of the above table in the htable. In the log we can see, that the load is done in the alphabetic order of the key_name and it fails to load the last entry "VERSION" : Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [VERSION] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [120104-1734] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6) If I add a new entry named "WWWWW", then the failure occurs on this entry that is the last alphabetic entry : | 10000 | WWWWW | toto | 0 | 0 | Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [WWWWW] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [toto] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6) Attached the kamailio log for each test.

My first attempt (see kamailio.cfg.ok) shows that the problem doesn't occur. In the second attempt (see kamailio.cfg.ko) I add instructions previously removed from the original .cfg file. I have determined that, depending on the instructions that follows the "modparam("htable", "fetch_rows", 1000)" line, the "key type must be string (type=6)" error occurs or not. In this ko file, if I comment out the following sequence, the error occurs : modparam("htable", "fetch_rows", 1000) #!!ifdef FIXED_ROUTING #modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") #!!else #modparam("htable", "htable", "abpqHash=>size=12;dbtable=abpq;") #modparam("htable", "htable", "zabpqHash=>size=12;dbtable=zabpq;") #!!endif modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") I hope my explanation is clearn and there are people who can help me on this problem that causes kamailio to not start.

Doubt parsing multipart SDP
by Albert Petit 03 Apr '17

03 Apr '17

Hi list, I am having some issues parsing multipart INVITE [1] when calling force_rtp_proxy . I tried to upgrade to Kamailio 5 to see if maybe i was using too old code but seems not the case. Log of error is: Apr 3 18:31:21 mcptt /usr/sbin/kamailio[3232]: INFO: <script>: forcing RTP proxy for INVITE message Apr 3 18:31:21 mcptt /usr/sbin/kamailio[3232]: ERROR: <core> [core/parser/parse_content.c:370]: decode_mime_type(): ERROR:decode_mime_type: parse error near in [application/vnd.3gpp.mcptt-info+xml] char[51][3] offset=16 So seems there is some issue using Content Type application/vnd.3gpp.mcptt-info+xml in a multipart SIP message But this content type is accepted at following 3GPP spec: http://www.etsi.org/deliver/etsi_ts/129100_129199/129165/13.06.00_60/ts_129… Checking implementation of parse_content.c I see ". - _ +" characters are accepted so i am not sure what is failing. I did some test and if instead of that Content-Type: application/vnd.3gpp.mcptt-info+xml i use Content-Type: application/mcptt no errors are seen in Kamailio logs and ports are replaced succesfully.

Doubt about MI Datagram module in Kamailio 5
by Albert Petit 03 Apr '17

03 Apr '17

Dear list, I've recently upgraded to Kamailio 5 in order to avoid issue parsing SDP multipart bodies which think are fixed in the update ( - symbol rejected in content type) . I could upgrade without issues from my kamailio 4 dev deployment but i cannot load anymore MI_Datagram module (seems not present in Kamailio 5 , MI Datagram module i refer to: http://www.kamailio.org/docs/modules/4.3.x/modules/mi_datagram.html ) Can i use MI Datagram module still in Kamailio 5 ? Thanks Albert

Exclusive: Quitting the fast life of open-source SIP
by Alex Balashov 03 Apr '17

03 Apr '17

(Filed by UC Celeb Talk - 1 Apr 2017.) BERLIN (Tegel), GERMANY--In the now-infamous breakdown episode on the VIP tarmac at Berlin's Tegel Airport, Alex Balashov shocked the IP telecoms celebrity world last month. Shielding his eyes from the punishingly bright daylight of an overcast day in northern Germany, Balashov climbed out of his Gulfstream G650 jet, clutching a half-finished bottle of Woodford Reserve, and announced his sudden retirement from the "fast life" of open-source SIP consulting to a waiting gathering of techn business reporters. "I'm not with this 'live fast, die young' VoIP s*** anymore," he reportedly shouted, before collapsing and vomiting profusely on the red carpet. UC Celeb Talk's own Benjamin Brant sat down with Balashov in an exclusive interview to learn more about what happened, even as the telecoms industry continues to digest the shock meltdown. -- BRANT: Everyone's dying to know, what was going through you head at that moment? BALASHOV: Funny how you mention dying. I want to live to see 35, man. I can't handle the SIP biz anymore. BRANT: What do you mean? You seemed to have all the makings of an open-source SIP superstar. BALASHOV: I can't keep up with the drinks anymore, the three day-long parties, the paparazzi, always watchin' my back at ClueCon... BRANT: When'd you realise it might be time to call it? BALASHOV: I'll tell you when. It was Kamailio World '16. Man, those vodka + Club Mate drinks they pour down at Fokus are something else. They'll really get you thinking about things. BRANT: So you had a cocktail and thought better of your entire life as a SIP celebrity? The fans, the adulation, the glory? BALASHOV: When you wake up at 3 PM at the Park Inn on Alexanderplatz with a $31,000 room service bill on your AMEX, a goat wandering around, and reporters in your face, you tell me with a straight face you're not gonna take stock of your life and make some changes. BRANT: That really happened? BALASHOV: That's what I'm trying to tell you! That's Kamailio World, dude. That's the SIP software engineering culture. You wanna ITSP and WebRTC? You're gonna have to bro down! BRANT: Surely not everywhere. What about the IETF? BALASHOV: Those guys drink more than ANYONE. Have you seen the SIP Outbound RFC? BRANT: That's the work-product of an alcohol-fuelled creative orgy? BALASHOV: It's the work product of something-something. I don't know if I'm allowed to identify the uh, substance in question. BRANT: How are you going to live without the private jet? If I had a G6, I wouldn't just turn over the keys. BALASHOV: Yeah, I mean, open-source VoIP consulting has its upsides. It's a fine way to make a living. But it's just not worth it. Besides, hourly operating costs are through the roof. BRANT: But you were an icon, and quite a ladies' man too! How do you walk away from that? BALASHOV: Look man, of course women are gonna mob you when you're a SIP consulting star. That's just part of the open-source tech life in general. But it's fake, man. They don't love you. They don't want to know who you are inside. They just want you 'cause you know all about the SIP transaction state machine, loose vs. strict routing, cross-compiling Kamailio. They just got a crush on you 'cause you know presence and parallel forking race conditions. I want something real. BRANT: But that's part of the social bargain of being an open-source SIP celebrity. Didn't you once boast of having uh, lady friends, "in different geographic and non-geographic operator codes"? BALASHOV: Yeah, and that's cool, but I want to come home to a woman who loves me for me, not Mr. 3... ... 02, Moved Temporarily, but not happy necessarily. Feel me? BRANT: What happened at ClueCon? BALASHOV: You talking about the bullets Acme Packet ventilated me with? BRANT: Five of them, as I heard. BALASHOV: Well I'm still standin'. Took those shots and smiled. BRANT: I know you guys have a kind of omertà about this stuff, but I've got to ask: why? BALASHOV: I ain't worried, kids growing up in today's world need to learn the truth. They act like I was dealing transcoding licences on their block. O.G. 729. BRANT: But that wasn't what gave you a wake-up call that the SIP game is sharper than a razor blade? BALASHOV: Hell no, it wasn't their block. That fake-ass east coast channel partner crew can cash me outside howboudah? BRANT: How exclusive is Kamailio World? BALASHOV: It's one of the most exclusive clubs I've ever hit up. Lines wrapping around blocks. And the bouncers. Damn. BRANT: The bouncers? BALASHOV: Those dudes are harsh. BRANT: On a scale of 1 to Berghain, how bad is it? BALASHOV: All I know is, one time some squirrely guy in the audience asked a moderately new-blood question like, "If a Record-Route header has been added by an intermediate proxy, is it proper of a SIP User Agent to populate the Request URI of subsequent in-dialog requests with the Record-Route URI, or should it be the remote Contact?" Half the room got up like it was ready to curb-stomp that little face. Guy didn't know what he got himself into--a room full of elites. BRANT: So what happened? BALASHOV: Someone was like, "Bounce this fool! He don't know how to act." So these three muscular Kaiser Wilhelm-looking dudes--moustaches and all--in sunglasses roll up and drag this guy through the Atrium, out the doors and dump him straight out onto Anna-Louisa-Karsch-Straße. BRANT: Damn. Ejected out of the saloon. BALASHOV: Yo, that dude was dismissed from the premises. BRANT: So what do you see in your future post-SIP life? BALASHOV: I'm thinking about starting a bakery. A friend threw it out there as a way to kind of atone for all this and get straight with Jesus. Gonna bake really big cookies. You know, huge ones, like a small pizzas? But recognise--they're actually cookies. BRANT: Got any advice for those who bright young upstarts who haven't turned over a new leaf and thrown in the towel yet? BALASHOV: Come on down to Kamailio World #5, May 8-10 2017 in Berlin. You'll see your life in a new way. Registration and more information online at https://www.kamailioworld.com/k05/

Kamailio 6.0 architecture
by Olle E. Johansson 03 Apr '17

03 Apr '17

Dear Kamailians! We got news for you! The Kamailio 6.0 architecture is finalised! It's something we've been working on for a long time in the project team and you've already seen part of it in the recent Kamailio 5 release - the KEMI interface for LUA. We've realised that we have too many modules, especially all those IMS* modules. And the core is getting slimmer and slimmer. This is what we're going to do: * All RPC, EVENTAPI,AUTH, JSON, TM, HTTP_CLIENT and TLS modules will be integrated back into the core. * The EVENT API will be the core API for external modules * The rest of the functionality in the modules will have to be rewritten in LUA and maintained as separate GITHUB projects outside of the core After successfully integrating LUA into the heart of Kamailio and exposing the Kamailio API we have decided to make life more simple for the core maintainers. Maintaining well over 100 modules took too much time, and who cares about some of the stuff? Billing, least cost routing and all the other crazy stuff in modules are going away anyhow as all services will be free. Calls really wants to be free. And presence is no longer needed, we'll just tap into the mobile phones from the core to know where everyone is. The removal of the modules will take place during the month of April 2017 and a new core will raise like a Fenix from the ashes, a much larger, monolithic and complex core with new functionality that will take Kamailio to new areas, like a message bus for games, an API server for mobile yoga apps and a control plane for embedded IoT devices. "Kamailio everywhere" is the new slogan for the Kamailio project. - "We will all remember April 1st 2017 as a new start of the project" says Olle-Carsten Mierla, the new elected project leader. "From now on, Kamailio aims to be a standard part of every operating system distribution, defining the new core of the Internet.” We hope all of you join us in this effort and refrain from reporting any bugs or other disturbing issues while we rebuild the new Kamailio. /O

Configuring Kamailio as a "VoIP traffic reflector"
by Tahiro Hashizume 31 Mar '17

31 Mar '17

Hi there, This e-mail is going to be lengthy and I hope you will not get frustrated (like I am, for different reasons described later) by reading it all from the beginning to the end since I have just warned you :P You have absolutely no need for reading the entire post unless you are crazy enough read about what I do for fun in given circumstances. Basically, I would like Kamailio and Asterisk to run on the same box in such a way that A.)Asterisk listens on eth0 (on 10.1.1.15/24 with ProxyARP enabled) for incoming SIP register requests from VoIP-ATAs B.)Kamailio listens on five IP addresses on dummyN which has 10.1.1.1N/32 (N=0-4, so dummy0 has 10.1.1.10/32, for example) making five SIP+RTP sessions to the same remote host to appear as if they are from five different hosts - so that a single instance of Asterisk running on debian may be registered (through Kamailio) on the same remote host by using five different accounts and source IP addresses. I know Asterisk alone cannot do this (even by running multiple instances of it) and that there have to be five instances of both SIP-Proxy and RTP-Proxy so that the source address can be literally spoofed. Should be simple, but so far cannot find good sources of reference. I need your advice. Thanks in advance. << Backgrounds - read only if you are curious >> The so-called frustration is when your needs are not realized due to technological limitations. I have years worth of frustration on the VoIP setup at home and that's totally NOT your fault. Written below for those who happen to be curious should sound interesting, so here is the situation I'm facing; I'm in Japan and our infrastructure is well within the definition of NGN which in my case includes a low-latency VoIP to replace the traditional PSTN. (NTT will end ISDN in 2020, copper-line PSTN in 2025, as announced so far.) The service is provided by NTT (former state-run telecom) of Japan and works on FTTH which carries: a.)PPPoE for those who wish to get IPv4&IPv6 connectivity - which for the most part is so that users get to choose their favorite ISP. b.)WAN-reachable IPv6 traffic c.)WAN-unreachable IPv4 for SIP based services (address blocks reserved and announced by AS9595) Given the fact that b.) and c.) are only applicable (optionally and respectively) to those who signed up for the native-IPv6 (we call it IPoE, oddly) service and to those who signed up for the VoIP service, it's essentially an L2 transport service for PPPoE to your ISP - very much like the way we had our phone-line and ISP (dial-up) separately signed up for in the old days (hence I call it the access-line service). I've made a switch over to VoIP-based PSTN from the copper-line in April 2011 after seeing that copper-line PSTN served no better in case of emergency like 3.11 when people want to call others to see if their loved one are okay - on the evening through the night of March 11 2011, our traditional PSTN stayed at its capacity limits while VoIP-based means of communication (incl. Skype, surprisingly) stayed intact. That was the wake-up call. Now, upon signing up for the VoIP service, the user receives a box so called HGW (stands for Home Gateway) which is very much a SIP+RTP UA on its WAN side and SIP+RTP server on LAN side (up to 5 UAs may register if the UA supports "sip session-timer"). And this HGW is being the pain that drove me to writing this e-mail - it only allows one SIP-register per IP address. Further, looking into the specs requirements for HGW published by NTT (=there's a centralized documentation for it since the designs and manufacturing of HGW is split across several companies), there's a part which basically says: "One SIP register to HGW from a UA on LAN should be able to handle (but not limited to) one data session. An UA on HGW's LAN side may support multiple-data session per SIP register(optional)." - which to me reasonably explains why my HGW only allows one SIP-register per IP address. My gyess is that the unwritten assumption here is "one sip register"="one physical phone", which is quite understandable. Regarding the fact that NTT optionally provides services like: 1.)additional phone numbers 2.)multi-data sessions(RTP for voice, for example) ...on one trunk. This, and also in accordance with the technical specs. requirements for HGW above means supporting multiple RTP sessions either terminated or originated by an Asterisk box which sits on the HGW's LAN side requires that a single instance of Asterisk on a debian box somehow uses multiple IP addresses (with or without the use of other software). The simplest way of doing this (to me) seemd like running five instances of RTP(proxy)+SIP(proxy) which will each listen on one of five IP addresses, to which the Asterisk instance in question could establish one session of SIP+RTP each. The idea seemed simple enough, but there did not seem like good selections of software years ago. I have once given up on the implementation years ago, altered the NTT-supplied HGW with a third-party product (NVR500 by YAMAHA which on its LAN behaves as a MGCP+RTP server) in order to maximize the stability of the phone system. This was due to the fact that the x86-box I was using was hardware-unstable and that the HGW's behavior was something I did not like dealing with (recently solved). I've decided to make a come-back to Asterisk recently since I recently started using hylafax running on a RasPi with RS232 modem hooked up to it but with missing support for CID since the Japanese equivalent of CID (we call it Number-Display) does not follow the Bellcore standards and the modem I use only supports Bellcore standards- going VoIP again and running iaxmodem could solve this issue. -------------------------------------------- Tahiro Hashizume Department of Electrical and Electronic Engineering at Tokyo Denki University 5 Senju-Asahi-cho Adachi-ku Tokyo, JP1208551 Japan --------------------------------------------

log_custom module question
by Anonim Stefan 29 Mar '17

29 Mar '17

Hi, I'm trying some logging via UDP, using log_custom module. I've noticed that the logs are always sent through the first interface in the config "listen=" rows. Now, is there a way to listen on that interface, in order to log_udp() on it, without being able to send/receive any SIP on it? (i.e. disabling SIP capability and use it only for logging via UDP) Thank you, Stefan

Kamailio Registration load Issue
by Jade SZ 28 Mar '17

28 Mar '17

Hi Guys, I am running a simple REGISTER load test on: 1) Kamailio sever with 2 cores - mem 5G 2) Kamailio server with 4 cores - mem 16G Both are EC2 instances. At -r = 500 i.e. 500 reg/sec sipP test works fine with very few re-trans. But when i increase it to 800 reg/sec it starts retransmissions in bulk. I don't see server's CPU, load-avg or memory shooting. Running everything by default, even using kamctl to start the instance. So I have not tuned any params yet. My main concern is how can I make server choke and get its actual capacity, and avoid these retransmissions as apparently kamailio is not even utilizing 2 cores and CPU usage is under 10 always. Results of both server is same i.e. 500 reg/sec max so I am sure there is some problem that needs a fix, but need some hints here. Also used multiple SIPp's to rule out if it is SIPp issue, but after 500 I see same problem. Regards, JSZ

new keepalive module ?
by Guillaume Bour 28 Mar '17

28 Mar '17

Hi all, I would like to implement destinations keepalive in drouting module (as it is done in dispatcher). But instead of duplicating what's implemented in dispatcher, I think it would be more clever to create a new module dedicated to pinging destinations, and to plug drouting, dispatcher and other modules to this new one What's you opinion about that ? Cheers, Guillaume

Presence + RLS + XCAP
by Paul Smith 27 Mar '17

27 Mar '17

Hi I am struggling to figure out how to build and test an integrated presence server with Resource-List (rls.so) and XCAP (xcap_server.so). I am confused about what is meant to happen and how to debug it. Not sure if I am suffering from incompatibilities, configuration errors, or bugs… I have not found an up to date guide on configuring an integrated presence, rls, xcap server so I have used old tutorials, module documentation and some course code review … but I’m pretty confused now! I am using Snom phones and Jitsi (on Mac) to test. I have a kamailio Registrar which proxies all presence messages to the separate kamailio 4.2 Presence server. REQUIREMENT : Contact Presence ============================= I would like to get a SUBSCRIBE from the Snom phone to subscribe to a contact-list resource list, and to receive a NOTIFY with all of the presence states for those contacts. Relevant snom settings? Contact List URI: this generates a SUBSCRIBE with event:presence I believe that: ========== presence module should be managing the individual user presence and dialog states xcap module should allow me to use HTTP / curl to edit the resource lists rls module should be managing the mapping from a resource list subscription to the individual presence states and generating the aggregated NOTIFY messages. each device should then be able to SUBSCRIBE to a resource list uri and then receive an aggregated NOTIFY for all of the watched entities. Current status: =========== SUBSCRIBE sip:org1a-contacts@*****.co.uk SIP/2.0 v: SIP/2.0/UDP 192.168.1.15:59594;branch=z9hG4bK-qllzlgs3xf43;rport f: <sip:org1a@*****.co.uk>;tag=wwasqc6lmb t: <sip:org1a-contacts@****.co.uk> i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 1 SUBSCRIBE Max-Forwards: 70 User-Agent: snomD375/8.9.3.46 m: <sip:org1a@192.168.1.15:59594>;reg-id=1 Event: presence Accept: application/pidf+xml, application/rlmi+xml, multipart/related Supported: eventlist Expires: 3600 l: 0 … auth handshake SIP/2.0 202 OK Record-Route: <sip:10.210.160.13;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes> Record-Route: <sip:**pubip**;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes> v: SIP/2.0/UDP 192.168.1.15:59594;received=**recvip**;branch=z9hG4bK-8wufiv1ua3ne;rport=60554 f: <sip:org1a@****.co.uk>;tag=wwasqc6lmb t: <sip:org1a-contacts@*****.co.uk>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-d30e i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 2 SUBSCRIBE Expires: 3600 Contact: <sip:10.210.160.16:5060;transport=udp> Server: kamailio (4.2.0 (x86_64/linux)) Content-Length: 0 … and then the snom receives an empty NOTIFY.

I have a rows in the XCAP table for the Resource-List curl -d @/tmp/contacts-resource-list.xml -vvv -X PUT http://109.104.108.23:5060/xcap-root/resource-lists/users/sip:org1a-contact… relevant row in xcap table: | 3 | org1a-contacts | *****.co.uk | <?xml version="1.0" encoding="UTF-8" standalone="no"?><resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists"><list name="team"><entry uri="sip:1002@****.co.uk"/><entry uri="sip:1001@****.co.uk"><display-name>bob</display-name></entry><entry uri="sip:1003@****.co.uk"><display-name>test1</display-name></entry><entry uri="sip:1006@****co.uk"><display-name>test1006</display-name></entry><entry uri="sip:1007@****co.uk"><display-name>test1007</display-name></entry><entry uri="sip:1008@h****.co.uk"><display-name>test1008</display-name></entry><entry uri="sip:1009@****.co.uk"><display-name>test1009</display-name></entry> <entry uri="sip:1005@****.co.uk"><display-name>testing1005</display-name></entry> <entry uri=“sip:org1a@****.co.uk"><display-name>testingorg1a</display-name></entry> <entry uri=“sip:org1c@****.co.uk"><display-name>testingorg1c</display-name></entry></list></resource-lists> | 4 | sr-1490270411-10965-2 | 0 | /xcap-root/resource-lists/users/sip:org1a-contacts@****co.uk/index | 0 | I have rows in the presence table for the entities that I want to track e.g. | | | 2889 | org1c | ****.co.uk | presence | a.1490270411.10942.42.1083 | 1490277099 | 1490273499 | <?xml version="1.0 " encoding="UTF-8"?> <presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:im="urn:ietf:params:xml:ns:pidf:im" entity=“pres:org1c@*****.co.uk"> <tuple id="snom370-000413260935"> <status><basic>open</basic> <im:im>Available</im:im> </status> <contact priority="1.00">sip:org1c@****.co.uk</contact> <note xml:lang="en">Available</note> </tuple></presence> I am running kamaiio 4.2 Question : Should I have an resource-services row too? Or does rls.so infer the relationship using the URI? When I use jitsi to manipulate its contact list it only inserts 2 rows into the xcap table and I cannot get a SIP Subscribe to connect to that resource list either. Question : What should the curl PUT commands and XML docs look like to build a valid RLS service (is there a good example anywhere)? Question : Is there an example config or doc anywhere showing how to build integrated presence, rls, xcap? Question : Has anyone got this working with Snom and or other handsets… the standards and implementations seem vague / inconsistent? Note: There is another Snom setting (Extension Monitoring Call Pickup List URI:) which produces a SUBSCRIBE with Event:dialog but which should allow a button/lamp/callpickup/BLF for the buddy contact. I’d like to get that working too, but recognise that rls.so does not handle dialog messages by default, so I’m starting with Presence... Paul

Important problem with this test : if ($var(i:maxRangeInx)==$null)
by Ginhoux, Patrick 27 Mar '17

27 Mar '17

Hi, I'm continue my job to 'migrate' my 3.3.1 kamailio.cfg script on a RHEL 6.2 server to the 5.0.x kamailio version on a RHEL 7.1 server, and I encounter a major problem with the '== $null' test in the script. My original script (3.3.1) contains this sequence : $var(i:rangeInx)=0; $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange"); xlog(" imbxRangeInx value before test : '$var(i:maxRangeInx)' "); if ($var(i:maxRangeInx)==$null) { $var(i:maxRangeInx)=99; } xlog(" imbxRangeInx after test : '$var(i:maxRangeInx)' "); ==> The results are : imbxRangeInx value before test : '0' imbxRangeInx value after test : '99' I run the same script on my new server and I get '0' before and after the test. I attempted another kind of test to try to figure out where the problem is. So I write the simple test (with kamailio 5.0.x) : $var(i:rangeInx)=0; $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange"); $var(toto) = $null; if ($var(toto) == $null) xlog ("toto true"); else xlog ("toto false"); The result I got is always 'toto false'. So it appears to me that the test '== $null' doens' that gives a good result with kamailio 3.3.1, doesn't return the same with kamailio 5.0.x. That is a major issue for me and it let me confused about the possibility to move to kamailio 5.0.x. Have people an idea / explanation, why this issue ? Cordialement Patrick GINHOUX

Cannot yum download from download.opensuse.org, no mirrors
by Shadowy Man 27 Mar '17

27 Mar '17

This is only happening for one particular block of IP's. I can download from other blocks. I suspect it is being done on the download.opensuse.org end for some reason. It appears to be the entire xx.xx block of which I only use a few addresses from. I will probably have to try contact them about it. What I would like to ask is why Kamailio does not have any mirrors? If there were then this would not be a problem. It would just failover.

Regex module having trouble with large regex expressions in kamailio 4.4.5
by Tim Balmer 24 Mar '17

24 Mar '17

Hi, I discovered some strange behavior from the regex module yesterday (kamailio version 4.4.5). For example we have the phone number 0033755500381 that we try to match with the following kamailio code: #!define REGEX_FF_NEG_INTERNATIONAL "6" ... if (pcre_match_group("$rU", REGEX_FF_NEG_INTERNATIONAL)) { # Do something } When the content of our regex groups file is like this: [6] ^(\+|00)3(0690|0693|0694|0695|0697|0698|0699|36|37|4160|46|47|51160|511691|511693|511696|511891|511893|511896|513|516091|5160921|516093|516096|516391|516392|516393|516396|516591|516592|516593|516596|516691|5166921|516693|516696|5191|5192|5193|5196|538|54388|543 89|546|5475|5477|548|567117|5672|5677|5679|5692|5694|5696|5698|5699|5795|5796|5797|5799|58299|584|5850|5948|5987|5988|5989|59988|59989|620|630|631|670|706|712|725|728|774|776|8591|8592|8595|8597|8598|8599|8620|8621|8630|8631|8640|8641|8643|8649|8650|8651|8660| 8661|8664|8670|8671|869814|906698|93) The above if statment is not matching, although it should match according to any regex validator (for example https://regex101.com/ ) But when I split the above regex in smaller parts, like this: [6] ^(\+|00)306(90|93|94|95|97|98|99) ^(\+|00)336 ^(\+|00)337 ^(\+|00)34160 ^(\+|00)346 ^(\+|00)347 ^(\+|00)351(160|1691|1693|1696|1891|1893|1896|3|6091|60921|6093|6096|6391|6392|6393|6396|6591|6592|6593|6596|6691|66921|6693|6696|91|92|93|96) ^(\+|00)3538 ^(\+|00)354(388|389|6|75|77|8) ^(\+|00)356(7117|72|77|79|92|94|96|98|99) ^(\+|00)357(95|96|97|99) ^(\+|00)358(299|4|50) ^(\+|00)359(48|87|88|89|988|989) ^(\+|00)3620 ^(\+|00)363(0|1) ^(\+|00)3670 ^(\+|00)3706 ^(\+|00)3712 ^(\+|00)372(5|8) ^(\+|00)377(4|6) ^(\+|00)385(91|92|95|97|98|99) ^(\+|00)386(20|21|30|31|40|41|43|49|50|51|60|61|64|70|71|9814) ^(\+|00)3906698 ^(\+|00)393 Then the exact same regex module call as before does result in a match as expected. So to me it looks like the regex module is having trouble with large regex expressions, I did check the logs but there is nothing strange there, that means also the large expression is correctly loaded according to the logs while in fact it is not working. Checked the regex module documentation but there I cannot find any limits regarding to the size of invididual expressions. Is it me missing something or did I discover a bug in de regex module? Best Regards, Tim Balmer Edutel BV

Question on the debug change level command with 5.0.x
by Ginhoux, Patrick 23 Mar '17

23 Mar '17

Hi, Previously, in my kamailio.cfg 3.3.1, the debug level is set using the 'debug' option. Then with the MI_FIFO module it was simple to change debug level on the flight using the simple command 'kamctl fifo debug <new value>'. Moving to kamailio 5.0.x, there is no more MI_FIFO module. In the kamailio.cfg, I still have the 'debug' option set; so I'm looking for the command to use to change the debug level. I look at the debugger module that seems the solution. So I add the following lines in y script: debug=4 loadmodule "debugger.so" modparam("debugger", "log_level", 1) modparam("debugger", "mod_hash_size", 5) modparam("debugger", "mod_level_mode", 1) Then I try to use the following commands : This one retrieves the debug level set by the debug=4) : [root@vm-vse02-siprouter1 kamailio]# kamcmd dbg.get_mod_level core 4 This one changed the debug level for the core module [root@vm-vse02-siprouter1 kamailio]# kamcmd dbg.set_mod_level core 2 200 ok Same commands can be used for each of the module loaded: [root@vm-vse02-siprouter1 kamailio]# kamcmd dbg.get_mod_level tm 4 [root@vm-vse02-siprouter1 kamailio]# kamcmd dbg.set_mod_level tm 2 200 ok [root@vm-vse02-siprouter1 kamailio]# kamcmd dbg.get_mod_level dispatcher 4 [root@vm-vse02-siprouter1 kamailio]# kamcmd dbg.set_mod_level dispatcher 2 200 ok Each command only applies to a specific module. I don't find a 'global' command that I could use in the same manner as the old 'kamctl fifo debug' command. Is there something I missed in my config ? Cordialement Patrick GINHOUX

Presence + RLS + XCAP
by Paul Smith 23 Mar '17

23 Mar '17

Hi I am struggling to figure out how to build and test an integrated presence server with Resource-List (rls.so) and XCAP (xcap_server.so). I am confused about what is meant to happen and how to debug it. Not sure if I am suffering from incompatibilities, configuration errors, or bugs… I have not found an up to date guide on configuring an integrated presence, rls, xcap server so I have used old tutorials, module documentation and some course code review … but I’m pretty confused now! I am using Snom phones and Jitsi (on Mac) to test. I have a kamailio Registrar which proxies all presence messages to the separate kamailio 4.2 Presence server. REQUIREMENT : Contact Presence ============================= I would like to get a SUBSCRIBE from the Snom phone to subscribe to a contact-list resource list, and to receive a NOTIFY with all of the presence states for those contacts. Relevant snom settings? Contact List URI: this generates a SUBSCRIBE with event:presence I believe that: ========== presence module should be managing the individual user presence and dialog states xcap module should allow me to use HTTP / curl to edit the resource lists rls module should be managing the mapping from a resource list subscription to the individual presence states and generating the aggregated NOTIFY messages. each device should then be able to SUBSCRIBE to a resource list uri and then receive an aggregated NOTIFY for all of the watched entities. Current status: =========== SUBSCRIBE sip:org1a-contacts@*****.co.uk <sip:org1a-contacts@*****.co.uk> SIP/2.0 v: SIP/2.0/UDP 192.168.1.15:59594;branch=z9hG4bK-qllzlgs3xf43;rport f: <sip:org1a@*****.co.uk <sip:org1a@*****.co.uk>>;tag=wwasqc6lmb t: <sip:org1a-contacts@****.co.uk <sip:org1a-contacts@****.co.uk>> i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 1 SUBSCRIBE Max-Forwards: 70 User-Agent: snomD375/8.9.3.46 m: <sip:org1a@192.168.1.15:59594 <sip:org1a@192.168.1.15:59594>>;reg-id=1 Event: presence Accept: application/pidf+xml, application/rlmi+xml, multipart/related Supported: eventlist Expires: 3600 l: 0 … auth handshake SIP/2.0 202 OK Record-Route: <sip:10.210.160.13;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes <sip:10.210.160.13;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes>> Record-Route: <sip:**pubip**;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes <sip:**pubip**;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes>> v: SIP/2.0/UDP 192.168.1.15:59594;received=**recvip**;branch=z9hG4bK-8wufiv1ua3ne;rport=60554 f: <sip:org1a@****.co.uk <sip:org1a@****.co.uk>>;tag=wwasqc6lmb t: <sip:org1a-contacts@*****.co.uk <sip:org1a-contacts@*****.co.uk>>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-d30e i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 2 SUBSCRIBE Expires: 3600 Contact: <sip:10.210.160.16:5060;transport=udp <sip:10.210.160.16:5060;transport=udp>> Server: kamailio (4.2.0 (x86_64/linux)) Content-Length: 0 … and then the snom receives an empty NOTIFY.

Or does rls.so infer the relationship using the URI? When I use jitsi to manipulate its contact list it only inserts 2 rows into the xcap table and I cannot get a SIP Subscribe to connect to that resource list either. Question : What should the curl PUT commands and XML docs look like to build a valid RLS service (is there a good example anywhere)? Question : Is there an example config or doc anywhere showing how to build integrated presence, rls, xcap? Question : Has anyone got this working with Snom and or other handsets… the standards and implementations seem vague / inconsistent? Note: There is another Snom setting (Extension Monitoring Call Pickup List URI:) which produces a SUBSCRIBE with Event:dialog but which should allow a button/lamp/callpickup/BLF for the buddy contact. I’d like to get that working too, but recognise that rls.so does not handle dialog messages by default, so I’m starting with Presence...

Status of db_cassandra
by Markus Bönke 23 Mar '17

23 Mar '17

Hello, We are thinking about to use kamailio as a sip registrar with cassandra as db backend. As I can see in the documentation for kamailio 5.0 it is only tested with Casandra 1.1.6 and 1.0.1, current version is 3.10 in the meantime. Is anyone using this module with newer versions of Cassandra? Is it stable? Thanks and regards Markus

getting source IP from Contact header
by Ali Taher 22 Mar '17

22 Mar '17

Hello everyone, I'm trying to get the host part from the contact header in the sip invite packet. Following is the contact header format: Contact: <sip:user_name@192.168.1.1:5060> What I want as result is 192.168.1.1 I searched among the pseudovairables and found $ct variable which reference to the body of contact header. (<sip:user_name@192.168.1.1:5060>) Is there a way to get directly the host (192.168.1.1) without applying transformation at the level of $ct. If not what transformation can achieve it. Thanks in advance. Regards, Ali

Alternative of SIPp for WebRTC2SIP load-test
by Jade SZ 21 Mar '17

21 Mar '17

Hi Guys, SIPp is great in testing pure SIP udp/tcp/tls but I was wondering if there is a similar tool for stress testing Kamailio websocket2sip. I am trying to load-test webrtc2sip kamailio's implementation closest to the real scenario. One way would be to fork multiple process of webrtc2sip client in loop. But would really like to hear how are kamailio webrtc users/community load-testing it for benchmarking their servers. Also roughly how much CPS they have achieved using single kamailio with webrtc enabled (share server specs as well) Thanks in advance. Regards, JSZ

do we need high available IP for S-CSCF?
by Valentin Christoph 21 Mar '17

21 Mar '17

Hi all, Maybe I need a small hint. I have got a configuration of 2 S-CSCF instances (both kamailio 4.4.5 with S-CSCF configuration, each on a separate virtual machine) in load sharing mode (50:50). Both instances work on the same "scscf" data base, so that it is only one S-CSCF from a logical point of view. Now I get into troubles with registration: * P-CSCF sends REGISTER to first S-CSCF * First S-CSCF answers with 401 Unauthorized an challenges the UE. So far everything OK. * Second REGISTER is sent to second S-CSCF (DNS SRV Load Balancing). * Second S-CSCF answers again with 401 Unauthorized (Error) * This goes back and forth until UE gives up to register This problem exists sporadically (approx. every fifth registration). Now the question: is it worth to debug this configuration or should we rather switch to high available IP configuration (if we want to use kamailio)? What's your opinion/experiences?

Siremis 4.3.0 with Apache 2.4
by kai.ohnacker＠cbc.de 21 Mar '17

21 Mar '17

Hello Community, I installed the Kamailio 4.4 and try to install the Siremis GUI based on apache 2.4. If I try to start the Siremis Wizard, the Webserver display the following line: "location.href='$url'"; exit; } ?>". The starting page of apache 2.4 is working fine, but the /siremis page doesn't. Due the installation I take the dedicated apache 2.4 commands. Are there some further requirements? Some ideas? OS: Ubuntu 16.04 Thanks a lot. Cheers, Kai

Hi, I use acc module for create cdr into db and also make acc log into db. After restart Kamailio cdr won't be created but acc log will be inserted into db. In the syslog also I see just the acc log. The dialog will be remove from db. I have read many threads. I know that it should work. Thanks for help!

Hi, There was a mistake in the file attached ; the short kamailio.cfg file (that makes kamailio to start) was not the correct one; attached the correct one. Have anyone an idea of this problem ?

ACC - Cdr enabled
by Diego Nadares 20 Mar '17

20 Mar '17

Hi guys, I have configured to use cdr with extra fields modparam("acc", "cdr_extra", * "sip_code=$rs;sip_reason=$rr;"* "hangup_src=$dlg_var(hangup_disposition);" "prefix=$dlg_var(prefix);gos=$dlg_var(gos);endpoint_type=$ dlg_var(endpoint_type);" "ip_a=$dlg_var(ip_a);ip_b=$dlg_var(ip_b);" Is this the right way to always save the hangup cause? Or is another better way? Because, when call is finished with a bye both fields are empty. The other thing is that I need to save, start_time and end_time with seconds.microseconds (1490013250.601707). Is this possible? Thanks! Diego

cisco spa502g issues
by ben＠wtf.com.au 19 Mar '17

19 Mar '17

Hi guys, we have a bunch of SIP phones behind a fire wall, with our kamalio server out on the internet. Most of them are the older SPA92x series, but we have some new SPA502g's. We have no problems calling between 92x and 502's. How ever the 502's calling each other do not get voice path. I have noticed that the phones REGISTER differently: AOR:: 5546@<our domain> Contact:: sip:5546@<OUR OFFICE IP>:1032 Q= Expires:: 180 Callid:: 4754c4f9-c67e1018(a)10.0.41.29 Cseq:: 43112 User-agent:: Cisco/SPA502G-7.6.2a State:: CS_DIRTY Flags:: 0 Cflag:: 0 Socket:: udp:<OUR SR IP>:5060 Methods:: 6815 AOR:: 5590(a)sip.skunkworks.net.au Contact:: sip:5590@10.0.41.14:5060 Q= Expires:: 1154 Callid:: 24435738-224b06db(a)10.0.41.14 Cseq:: 8012 User-agent:: Linksys/SPA921-5.1.8 Received:: sip:<OUR OFFICE IP>:1026 State:: CS_SYNC Flags:: 0 Cflag:: 64 Socket:: udp:<OUR SR IP>:5060 Methods:: 4767 The older 921 has its private IP in the contact, where as the newer 502 has the external IP of our office in the contact. Our file wall is a Watchguard T-10 (latest updates etc) with the SIP-ALG running. Any thoughts on where to start looking ? Cheers, Ben.

Generate extra cdr per dialog
by Diego Nadares 18 Mar '17

18 Mar '17

Hi Guys, I'm using acc module for accounting with the following conf: .... modparam("acc", "cdr_enable", 1) modparam("acc", "cdr_expired_dlg_enable", 1) modparam("acc", "cdr_start_on_confirmed", 1) modparam("acc", "cdr_facility", "LOG_LOCAL1") modparam("acc", "cdr_end_id", "end_time_dt") modparam("acc", "cdr_extra", "sip_code=$rs;sip_reason=$rr;" "hangup_src=$dlg_var(hangup_disposition);" "prefix=$dlg_var(prefix);gos=$dlg_var(gos);endpoint_type=$dlg_var(endpoint_type);" "ip_a=$dlg_var(ip_a);ip_b=$dlg_var(ip_b);" .... It works fine. At the end of the call the cdr is generated ok. BUT In MANAGE_FAILURE, If the first call failed and if there are more dests, we are generating a new call in the same dialog (Some of the dialog vars like ip_a, ip_b can change for the new dest ) I would like to generate both cdrs, the one that failed and the new one (with some dlg vars with new data). if(rtjson_next_route() && t_check_status("503")) { $avp(current_route) = $avp(current_route)+1; t_on_branch("MANAGE_BRANCH"); t_on_failure("MANAGE_FAILURE"); route(RELAY); exit; } Right now just the last call cdr is saved. I all ready made this work with db_acc (transaction oriented) but I think in my case it will be more reliable with cdr (dialog oriented). Thanks in advance! Diego.

Search for kamailio PERL module for 5.0 level
by Ginhoux, Patrick 17 Mar '17

17 Mar '17

Hi, I'm a beginner in the use of kamailio product, so I try below to explain my problem with my words: 1) PERL module issue : Some years ago a SIP Router proxy running RedHat 6.2 was developped using the kamailio version 3.3 and the following packages used : kamailio-3.3.2-1.1.1.x86_64.rpm kamailio-snmpstats-3.3.2-1.1.1.x86_64.rpm kamailio-mysql-3.3.2-1.1.1.x86_64.rpm kamailio-perl-3.3.2-1.1.1.x86_64.rpm We have the project to migrate this SIP Proxy to RedHat 7.1 and used the latest Kamailio v5.0.0 Release: kamailio-5.0.0-24.1.x86_64.rpm kamailio-mysql-5.0.0-24.1.x86_64.rpm kamailio-snmpstats-5.0.0-24.1.x86_64.rpm However I don't find the kamalio-perl package for RedHat 7.1. I see that the perl module has been renamed to 'app_perl' but I don't find it either for kamailio 5.0.0. 2) Kamailio.cfg script Our proxy used the kamailio.cfg from the sample of the 3.3.3 release. So can I reuse the same 3.3.3 kamailio.cfg file with the 5.0.0 release or should I migrate (rewrite it) from the 5.0.0 sample ? So I'm looking for some help on these issues. Is there people that had this case ? Thanks in advance for any answer. Cordialement Patrick GINHOUX PS : I just create my account today but don't get the email to validate it.

cisco spa502g issues
by Ben Kramer 17 Mar '17

17 Mar '17

Hi guys, we have a bunch of SIP phones behind a fire wall, with our kamalio server out on the internet. Most of them are the older SPA92x series, but we have some new SPA502g's. We have no problems calling between 92x and 502's. How ever the 502's calling each other do not get voice path. I have noticed that the phones REGISTER differently: AOR:: 5546@<our domain> Contact:: sip:5546@<OUR OFFICE IP>:1032 Q= Expires:: 180 Callid:: 4754c4f9-c67e1018(a)10.0.41.29 Cseq:: 43112 User-agent:: Cisco/SPA502G-7.6.2a State:: CS_DIRTY Flags:: 0 Cflag:: 0 Socket:: udp:<OUR SR IP>:5060 Methods:: 6815 AOR:: 5590(a)sip.skunkworks.net.au Contact:: sip:5590@10.0.41.14:5060 Q= Expires:: 1154 Callid:: 24435738-224b06db(a)10.0.41.14 Cseq:: 8012 User-agent:: Linksys/SPA921-5.1.8 Received:: sip:<OUR OFFICE IP>:1026 State:: CS_SYNC Flags:: 0 Cflag:: 64 Socket:: udp:<OUR SR IP>:5060 Methods:: 4767 The older 921 has its private IP in the contact, where as the newer 502 has the external IP of our office in the contact. Our file wall is a Watchguard T-10 (latest updates etc) with the SIP-ALG running. Any thoughts on where to start looking ? Cheers, Ben.

send_all blocks indefinitely
by Robert 16 Mar '17

16 Mar '17

H all, Recently, when I'm trying to load test Kamailio with a single proxy, it hung at around 15000 TPS. I attached gdb to one of the kamailio processes and I saw this: (gdb) where #0 0x00007fa8872366ad in __libc_send (fd=13, buf=0x7ffe6e0e5350, n=16, flags=-2027723091) at ../sysdeps/unix/sysv/linux/x86_64/send.c:27 #1 0x00000000004eb635 in send_all (socket=13, data=0x7ffe6e0e5350, data_len=16) at pass_fd.c:133 #2 0x00007fa4155a1b69 in tcp_close_connection (conn_id=28022) at tcp_funcs.c:199 #3 0x00007fa4155a363f in cleanup (start=0x7fa4540c3ab8, end=0x7fa42f92dca0) at tcp_funcs.c:337 #4 0x00007fa4155a1496 in timer_clean_tcp_connections (ticks=18583555, param=0x0) at tcp_funcs.c:165 #5 0x0000000000617f79 in fork_basic_timer (child_id=-1, desc=0x7fa4155a88e0 "Connections cleanup timer", make_sock=1, f=0x7fa4155a0ac6 <timer_clean_tcp_connections>, param=0x0, interval=30) at timer_proc.c:79 #6 0x00007fa4155a5816 in child_init (rank=0) at tcp_mod.c:176 tcp_func.c is something I wrote myself, which is basically a timer that runs periodically to try to clean up tcp connections that I no longer need. The code for tcp_close_connection is taken directly from usrloc > urecord.c > close_connection() >From the gdb output above, it seems like send_all is blocked and never returned, which led to my proxy to hang. In kamailio/src/core/pass_fd.c, I saw this: ... /** sends all data (takes care of signals) (assumes blocking fd) * returns number of bytes sent or < 0 for an error */ int send_all(int socket, void* data, int data_len) But in kamailio/doc/misc/TODO, I saw this: ... x [tcp] make send_all, send non-blocking ready ? x [tcp] tcp_send w/ timeout (to avoid waiting forever to send DOS) So, my question is, is send_all() suppose to block or not? I'm fairly new to how tcp and socket connection works. Any help will be appreciated!

SIP contact header question
by Jack Davis 15 Mar '17

15 Mar '17

Greetings, I have a general question about the usage of SIP contact headers in the context of using Kamailio as a SIP proxy. ________________________________ [ A ] --> [ Kamailio B ] ---> [ C ] Node A originates a SIP invite, containing a valid via header and URI while setting the contact address to a user@itself and delivers it to Kamailio B which is acting as a SIP proxy. Kamailio B then uses dispatcher routing to direct the Invite to node C, adding a via line with its own information as well as a record-route header with its own proxy information but retaining the same contact address from A. Node C establishes the call and then sends a re-invite to the Kamailio B proxy which is in turn sent to Node A. Node A responds with a 200 OK The problem arises when Node C tries to send an Ack in response to this 200 OK. The ack is being sent to the Contact address, rather than the routing already established in the initial dialog. ________________________________ My question is: should kamailio be rewriting this contact address with its own? Is that the best practice? My understanding is that the contact header is more so related to future requests within the same dialog ONLY when a record-route is not used. I would appreciate any clarification on the RFC or best practices in this scenario. Thank you, Jack Davis

Kamailio does'nt respond to packets from specific addresses
by עדי ויזגן 15 Mar '17

15 Mar '17

Hi everyone, I have the following problem: I have a Kamailio server that is connected to several Asterisk servers for load balacing in a LAN network with the IP's of 192.168.16.X. I recently connected with another company that is supposed to send me calls through the Kamailio server. The problem is this: I am connected to then with a cable from their network to mine. My port has the address 10.9.18.198 and they come from the address 172.18.177.18. When I get packets from their address (172...) I can see them getting to my Kamailio server, but the Kamailio does not respond. It only happens when I get packets from 172 source address. If I get from 192 or 10 adresses from my LAN network it works, and if I get packets from real world IP's through my WAN it works. Does anyone have any idea why the Kamailio does'nt respond to packets from 172 adresses? And how to fix this? Thanks in advance!

Hello, I would like to announce that many of the presentations at Kamailio World 2017 (May 8-10, in Berlin, Germany) are now listed at: - https://www.kamailioworld.com/k05/schedule/ Just several are not published yet, working to get all their details in place and expect to have the first draft of the schedule very soon. This edition takes place again at the same location in the famous city center of Berlin, the number of seats is limited, last year the event was fully booked. Do not delay too much your registration if you want to attend this year: - https://www.kamailioworld.com/k05/registration/ Thanks to the sponsors (https://www.kamailioworld.com/k05/sponsors/), it looks like we will be able to offer again some grants for students or underrepresented groups. More details will be sent out in the near future. Looking forward to meeting many of you in Berlin!
