by David Villasmil 12 May '17

12 May '17

Hello Guys, I have a kamailio 4.2.8 receiving on tls and i'm trying to forward on tcp, but AFTER the call is established, kamailio hangs the call with "SIPS required"... Has this happened to anyone? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

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

Re: [SR-Users] Can rtpproxy stream audio inside a call? (Maxim Sobolev)

Hi, Thank you very much for the answers! I'll have a play.

Technically speaking it can be done at any point after the media session has been established, but you need some kind of trigger to start/stop it from your routing script.

by Nguyen Tran Nhan 11 May '17

11 May '17

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. Thanks in advance for the answers. Cordialement Patrick GINHOUX

by Satish Patel 11 May '17

11 May '17

We have 1 stateless dispatcher and 3 proxy behind that dispatcher, when Proxy send BYE message then dispatcher bouncing back that BYE to Proxy and they playing ping pong. I think i am missing something.. How BYE get routed? in dispatcher i am not using loose_route() function also should i need to use that but again we running dispatcher in stateless. Here i put SIP trace: https://pastebin.com/vp9JCdNP Dispatcher config, Very simple.. route{ remove_hf("Route"); if (method == "INVITE") { record_route(); } if ( !ds_select_dst("1", "0") ) { xlog("L_ERR", "Unable to route \n"); sl_send_reply("500","Unable to route"); break; } forward(uri:host, uri:port);

Hi, I want to create conference without interact with IVR, so, trying to use Conference Factory URI. https://tools.ietf.org/html/rfc4579#section-3.2 I am looking for documentation but it seems very poor documentation.

Kamailio ro user
by Донат Зеничев 10 May '17

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.

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

kamailio crashes when it receives CANCEL
by Andy 08 May '17

Hi, when one of the proxies receive CANCEL, and it also the tries to generate 408 because of frv_inv_timer timeout at the sametime the e2e_cancel tries to generate a response to CANCEL - 487 at this time kamailio crashes from build_res_buf_from_sip_req, << for(lump=msg->reply_lump;lump;lump=lump->next) { len += lump->text.len; >> is it because the 408 generated deletes the reply lump or how can it be prevented. thanks for looking -- View this message in context: http://sip-router.1086192.n5.nabble.com/kamailio-crashes-when-it-receives-C… Sent from the Users mailing list archive at Nabble.com.

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
