Dialplan priority

Hello, I'm not sure to understand in which situation "pr" value is used. For example: if I have two identical rules except pr value: 1 with 1 and the second with 2, then the rule with pr 2 is never used. Someone can help me to understand? Thank you. The finality I'd like to accomplish is having some kind of load balacing between two values into "repl_exp" with the same inputs conditions. Thank you. Regards, Igor.

Call Transfer Scenario Using Freeswitch
by Sunil More 21 Aug '18

21 Aug '18

Hi All, I am using kamailio and freeswitch in my setup. While all users are registered on Kamailio, calls are routed to Freeswitch back to kamailio and then upstream providers. I can make user to user calls but in cases of transfer I am stuck. I am using a Polycom IP phone to test this scenario. While I initiate a attended transfer and click on transfer all the legs hangup. When I register all users on Freeswitch this works well. I am missing something on Kamailio side. Please point me in the right direction. Thanking You, Sunil More Ph : 9503338275

Enabling tcp_write_buf
by Gholamreza Sabery 21 Aug '18

21 Aug '18

Hi, In the documentation of "tcp_wq_max" option it is written that : > It has no effect if *tcp_write_buf *is not enabled. > > The interesting fact is that, there is not description of what it is and how one can enable it. There is even a question about it in the mailing lists: https://lists.kamailio.org//pipermail/sr-dev/2011-June/011521.html It seems that it is an inaccuracy in the documentation. If there is such an option how to enable it? Can anyone tell? Regards

Best practice/routing block for TCP connection errors to UAC?
by Anthony Alba 21 Aug '18

21 Aug '18

HI SR-Users Scenario: clients registered by TCP/TLS dropping off the network, kamailio stil thinks the client is registered and relays the INTIVE. The error occurs at the TCP layer so no failure route is called.

Kamailio 5.1 Nathelper sipping on different transport protocols.
by Володимир Іванець 20 Aug '18

20 Aug '18

Hello everyone! I have system with Kamailio v5.1 which needs to send OPTIONS packets to all active clients. Here is full Nathelper module configuration: *modparam("nathelper", "received_avp", "$avp(s:received)")* *modparam("nathelper", "natping_interval", 30)* *modparam("nathelper", "ping_nated_only", 0)* *modparam("nathelper", "sipping_bflag", FLB_SIPPING)* *modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org <sip%3Apinger(a)kamailio.org>")* It works fine if client is connected over UDP. But as soon as I will switch to TCP or register with client that uses WS, Kamailio stops generating OPTIONS. Does anyone know if it is correct behavior or something is wrong? Thanks a lot!

JSONRPC-S and async RPC commands
by Juha Heinanen 20 Aug '18

20 Aug '18

JSONRPC-S module README has: 2. Limitations This module does not implement asynchronous RPC commands. It is unlikely that asynchronous RPC commands will be executed from an JSON-RPC over HTTP client. Does this mean that, for example, tm.t_uac_wait command cannot be executed using JSON-RPC over HTTP? If so, why "it is unlikely that asynchronous RPC commands will be executed from an JSON-RPC over HTTP client", since those commands are currently commonly executed from XMLRPC client using xmlrpc module? It would be nice if JSONRPC-S module could be used as replacement of xmlrpc module. -- Juha

domain-based routing
by David Villasmil 19 Aug '18

19 Aug '18

Hello all, I need to set up a multi-domain kamailio, i think in terms of accepting invites to different domains is pretty simple by using the "alias" parameter, that much i have clear. My doubt comes from the fact that I need to route outgoing calls also based on the domain. As of today, i have single-domain kamailios using dispatcher to load-balance and failover said calls. I think i should be able to use dispatcher here as well, separating the dispatcher list by GID, so that Domain1->gid:1 Domain2->gid: 2 Domain3->gid: 3 and so on... I don't have registrations on this server and none are expected. So i'm thinking i will received the invites like: sip:12345@domain1.com sip:12345@domain1.com sip:12345@domain1.com and so on... How would you guys go about associating the domain with the gid list in dispatcher? Thanks a lot for your help! Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

I think this is done from the distribution package management and from the respective kamailio package. There are ways to adapt the installed dependencies during this installation, but you need to investigate it, as its depend on your linux distribution.

Registered User limit
by Philip Fleck 17 Aug '18

17 Aug '18

Is there a limit to the number of users which can be registered on Kamailio at any one time, or a configuration file which sets this. I have just installed Kamailio in a lab environment for testing purposes but I seem to only be able to register 1024 users, all remaining Register requests are ignored. I am not using a database to authenticate users or anything, just want to be able to register upto 10,000 users. regards Philip

Bogus event 8 in state 1 for dlg
by Phillman25 Kyriacou 17 Aug '18

Hi! I keep receiving the below logs on Kamailio: CRITICAL: dialog [dlg_hash.c:955]: log_next_state_dlg(): bogus event 8 in state 1 for dlg 0x7f59862cd440 [3685:10496] I understand that state 1 indicates an unconfirmed dialog, can anyone tell me what bogus event 8 is? The following is the call flow: User A ===> Kamailio ==> Provider >From the PCAP trace an INVITE is sent to the provider, the provider answers with 100 Trying, 180 Ringing and immediately an OPTIONS message with the same call id Kamailio Provider INVITE =================> 100 Trying <================= 180 Ringing <================ OPTIONS <================ Im assuming bogus event 8 is the OPTIONS message? Is an OPTIONS message normal in this case? Thanking you very much in advance for your help! Regards Phillip

how to enable tcp_write_buf?

16 Aug '18

I tried to issue mtree.list command using xmlrpc query that would result in large response, and got error Aug 15 18:12:07 char /usr/bin/sip-proxy[10348]: ERROR: <core> [core/tcp_main.c:618]: _wbufq_add(): (221375 bytes): write queue full or timeout (0, total 0, last write 55534052 s ago) Aug 15 18:12:07 char /usr/bin/sip-proxy[10348]: ERROR: xmlrpc [xmlrpc.c:811]: send_reply(): Error while sending reply Aug 15 18:12:07 char /usr/bin/sip-proxy[10367]: ERROR: <core> [core/tcp_main.c:3551]: handle_ser_child(): received CON_ERROR for 0x7f112ad22be0 (id 5), refcnt 3, flags 0x4018 I though that perhaps I could get rid of the error by increasing value of core var tcp_conn_wq_max. Description of the var tells: Maximum bytes queued for write allowed per connection. Attempting to queue more bytes would result in an error and in the connection being closed (too slow). If tcp_write_buf is not enabled, it has no effect. What is tcp_write_buf and how to enable it? I could not find anything about it in core cookbook. -- Juha

kamailio rtp proxy set not working
by ANOOP V M 16 Aug '18

16 Aug '18

I have installed kamailio 5.1.4 version in ubuntu server. I need to route RTP packets through kamailio with SIP packets. I will explain the way i have set up everything. I have installed rtpproxy by apt-get install rtpproxy. i have edited "/etc/default/rtpproxy" file with the line 'EXTRA_OPTS="-F -s udp:127.0.0.1:7722 -l 34.201.122.249 -d DBUG:LOG_LOCAL0"' i have edited "/etc/init.d/rtpproxy" file as follows, DAEMON=/usr/bin/$NAME PIDFILE="/run/$NAME/$NAME.pid I have provided "#!define WITH_NAT" and "modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")" in my cfg file. started rtpproxy "service rtpproxy start" when i try "netstat -tulpn | grep rtp" it shows udp 0 0 127.0.0.1:7722 0.0.0.0:* 1437/rtpproxy So i think the rtpproxy is currently running fine. Now we can go to kamailio part. I have gone through the document " https://www.kamailio.org/docs/modules/5.0.x/modules/rtpproxy.html" to set up rtpproxy in the cfg file. checking the rtp ports "kamcmd rtpproxy.list" showing { setid: 0 url: udp:127.0.0.1:7722 index: 0 disabled: 0 weight: 1 recheck: 0 } I have enabled rtp proxy using "kamcmd rtpproxy.enable udp:127.0.0.1:7722 1". So i think ports are ready for rtp proxy. Now i will explain the call flow. I have enabled log using L_BUG. when i try a call from hangout number through my twilio trunk to my asterisk freepbx extension, set_rtp_proxy_set("1"); giving true value. But rtpproxy_offer(); giving -1 as result. syslog shows some errors like below, Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:handle_command: received command "1934_4 Uc0,8,3,111,9,101 52001b5b71435b1c5392b39f2f6c975b@asterisk_ip:5060 asterisk_ip 14540 as4083c85f;1" Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: INFO:handle_command: new session 52001b5b71435b1c5392b39f2f6c975b@asterisk_ip:5060, tag as4083c85f;1 requested, type strong Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: ERR:create_twinlistener: can't bind to the IPv4 port 47926: Cannot assign requested address Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: ERR:handle_command: can't create listener Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:doreply: sending reply "1934_4 E10#012" And also my header is not changed.

Very strange reinvite behaviour
by Alex Balashov 15 Aug '18

15 Aug '18

Hi, We have a scenario like this: ITSP -----> Kamailio -----> Endpoint (UDP) (TLS) So, TLS is only being used on the last hop, and the upstream interaction with the ITSP is plain-old UDP. Kamailio has the following listeners: listen=udp:1.1.1.1:5060 listen=udp:1.1.1.2:5060 listen=tcp:10.0.0.1:5060 listen=tls:1.1.1.1:5061 At some point, 'Endpoint' sends a reinvite which has the following RURI: INVITE sip:1.1.1.1:5061 SIP/2.0 This is clearly improper, and caused a loop that led to the rtpengine SDP loop issue I previously reported in another thread. So, in an effort to stop this, I added the following: if(has_totag()) { if(loose_route()) { ... if(is_method("INVITE")) { xlog("L_INFO", "[R-MAIN:$ci] Re-INVITE received from $si:$sp to RURI $ru\n"); xlog("L_INFO", "[R-MAIN:$ci] Reinvite body: $mb\n"); if(!is_method("ACK") && uri == myself) { sl_send_reply("400", "Bad Request"); exit; } } } But it doesn't work. It appears that the '400 Bad Request' rejection never happens, presumably because the this domain doesn't match 'myself'. Another perplexing mystery: the log message containing the reinvite's '$ru' does not show a RURI of 'sip:1.1.1.1:5061', but rather the remote target in the initial inbound INVITE, which we also logged: Contact: "Anonymous" <sip:Restricted@3.3.3.3:5060> The log message says: [R-MAIN:...] Re-INVITE received from 4.4.4.4:5060 to RURI sip:Restricted@3.3.3.3:5060;lr. Note a subtle detail here: the ';lr' parameter is present, which is an attribute of the Record-Route inserted by the sending ITSP (3.3.3.3). It's at the bottom of the Route set, of course, below Kamailio's two RRs (inserted for the ingress UDP interface and the egress TLS interface): Route: <sip:Restricted@3.3.3.3:5060;lr> This leads to two questions whose causes seem to be related: 1. Why does Kamailio think the request URI of this re-invite is something other than what $mb reveals it to be? 2. Is that, presumably, why it does not match 'myself'? 3. Why would Kamailio think it is actually set to the far-end Record-Route URI? This is version: kamailio 4.4.5 (x86_64/linux) d48094.

rtpproxy or rtpengine with Kamailio and Asterisk

Good Morning everyone, Has anyone ever gotten rtpproxy/rtpengine to work with Kamailio and Asterisk? I have tried both, and even though I see no errors with either, and when I make calls I see rtpproxy/rtpengine traffic, I am still seeing media traffic go directly to and from Asterisk. I just can't get the media packets to not go directly from Asterisk to the Callee and visa-versa. Any ideas on where I am messing up in my kamalio.cfg file? Thank you!, -Steve

Rtpengine?
by Wilkins, Steve 14 Aug '18

14 Aug '18

HI All, I am not sure if I understand it correctly but I thought that I could use rtpengine to redirect media packets. My current SIP flow is => Softphone=>Kamailio=>Asterisk=>Kamailio=>Softphone, and Media flows from is Asterisk<=>softphone. But I don't want Media to flow this way. That is, I do not want Asterisk and the Softphone to be aware of each other. I would like the Media to go through Kamailio just like SIP packets do. I installed rtpengine and it starts and runs with no errors. I even see traffic with the call is made but media traffic still flows from softphone<=>asterisk. Any ideas? Thank you,

Re: [SR-Users] problem with compiling kamailio version 5.1.4 including a private Module

Hi Henning, thanks again. I found meanwhile the root cause. It caused as you said by the old logic of the make file. I used instead the new Formula of the tm module’s make file (as i remember). Consequently, it did not bring the compilation through those unwanted libraries. I will spot the details later when i am back in office next Monday. BR Abdulaziz On Thu 9.

app_lua and lua_run parameter count
by Asgaroth 13 Aug '18

13 Aug '18

Hi All, Quick question with regards the lua_run function in app_lua module. The documentation for v5.0.x states: "Execute the Lua function 'func' giving params as parameters. There can be up to 3 string parameters. The function must exist in the script loaded at startup via parameter 'load'. Parameters can be strings with pseudo-variables that are evaluated at runtime." Does this mean that lua_run can only have 3 parameters, or, does it mean that the function within the lua script can have up to 3 parameters? I have a function within lua that currently needs 3 parameters, so I'm hoping I can do the following: lua_run("some_function", "param_1", "param_2", "param_3") However, I'm not sure, from the documentation, if I can do this. On a side note, but related, can I pass defined variables/constants as parameters to lua_run too, for example, something like: #!define VAR_1 1234 #!define VAR_2 hello lua_run("some_function", "$rd", VAR_1, VAR_2) Some clarification would be greatly appreciated. Thanks for reading.

Lua KEMI crash
by Ivaylo Markov 13 Aug '18

13 Aug '18

Hello, I have Kamailio 5.1.4 (from deb.kamailio.org) running on a Debian 9 AMD64 VM with 1 CPU and 1G of RAM on ESXi. For KEMI I am using the liblua5.1-0:amd64 package, version 5.1.5-8.1+b2. The configuration is rather simple - dispatcher module reading the gateways from a file and forwarding everything to them based on a custom variable. There are 2 gateways in the file being pinged with OPTIONS packets every 10 seconds. Only a single SIP user is connecting to the machine (besides the occasional scanner). I can post the config if necessary, but I don't think that is the issue (see below). The crash has happened twice already - once on 2018-08-07 19:45 and 2018-08-08 14:33 EEST. You can find an excerpt from the Kamailio debug log at https://paste.fedoraproject.org/paste/bvyUMj3s5g2CcBN3JSBt5A/raw. As you can see, it crashes when trying to run the Lua route on an incoming packet. I am assuming the problem is this: Aug 8 14:33:14 lb-dev1 kamailio[13209]: *** Error in `/usr/sbin/kamailio': realloc(): invalid next size: 0x00005573dbff1ef0 *** However, I could not find any (direct) `realloc()` calls in the source for app_lua, so maybe this is an issue somehwere in liblua... Thoughts? Ivaylo

USRLOC db_mode=4 and server_id
by Darren Williams 13 Aug '18

13 Aug '18

I am currently using multiple instances of Kamailio with a common database and using the usrloc module with db_mode=4 and server_id to filter the contacts that get loaded at startup on each server. The problem I seem to have is that using the RPC call ul.add there I cannot see any parameter to send to specify the server_id. The server_id that the contact is given is 0. If I manually go into the db and modify the server_id everything works as expected. I think I must be missing something somehwere as I'mn sure you shouldn't need to do this. Can anyone help please. Thanks Daz

MYSQL and various
by Laura 12 Aug '18

12 Aug '18

Dear list, on my kamailio 4.4.7 i use interactions with MYSQL. For example .. i use it for some black list control and other like this.. sql_query("cb", "select id from blacklist where cli='$var(g2)' and (ippeer = '$si' or ippeer = 'ALL')", "rabl"); if($dbr(rabl=>rows)>0){ sql_result_free("rabl"); sl_send_reply("403","Forbidden blacklist"); exit; } sql_result_free("rabl"); I was wonder what was the best method to prevent the query going on if mysql don't respond for high load or other situation.. If Mysql is not able to reply to the query tight now the call continue over the configuration... what is the best way to prevent this and for examples drop it with a standard SIP 503 error. I have search on docs.. but i haven't found any valid way. Thanks Laura

11 Aug '18

hello dears when i'm using kamailio 5.2 as IMS i'm facing the following NAT issue : * when p-cscf handle a call from user1 to user2 that pre-registered on private address "192.X.X.X" (on another LAN) the user can't receive the invite message . in another word: proxy ip : 10.192.X.X user1 ip : 10.X.X.X user2 ip : 192.X.X.X the call scenario : user1 ---invite----> user2 (not arrived) * when p-cscf handle a call from user2 that pre-registered on private IP "192.X.X.X" (on another LAN) to user1 the user receive the invite message . the call scenario : user2 ---invite----> user1 (arrived) * when both of the user on different LANs the message 200 OK doesn't arrive to proxy :\ so based on that does any one has an experiment with NAT handling & nathelper module and how to configure it on P-cscf . thanks in advance

UDP workers block when one or more rtpengine instances go offline
by Sebastian Damm 10 Aug '18

10 Aug '18

Hi, we run multiple rtpengine servers to share the load. Whenever we need to take an rtpengine server offline, we used to just block the control port via iptables, then no new calls ended up on this instance of rtpengine. This worked pretty well in Kamailio 4.4.5. However, since Kamailio 5.0, and the problem persists with 5.1.4, Kamailio hangs almost immediately after we block the control port traffic. In the log file there are almost no packets processed except every few seconds, which looks like a timeout thing. Did we configure anything wrong there? Or is the "dead rtpengine detection" just broken? Our configuration: loadmodule "rtpengine.so" modparam("rtpengine", "rtpengine_disable_tout", 120) modparam("rtpengine", "setid_avp", "$avp(rtpsetid)") modparam("rtpengine", "rtpengine_sock", "0 == udp:1.2.3.4:9001=2 udp:1.2.3.5:9001=2 udp:1.2.3.6:9001=2") modparam("rtpengine", "rtpengine_sock", "1 == udp:2.3.4.5:9001=2") Any help appreciated. Regards, Sebastian

kamcmd htable.reload propertiesHash problem
by Ginhoux, Patrick 10 Aug '18

10 Aug '18

Hi, I run Kamailio 5.0.1 with MariaDB database. There is no issue at the initialization, meaning the db is opened by kamailio and the hash tables loaded from the db tables. Example: # kamcmd htable.dump propertiesHash { entry: 1 size: 1 slot: { item: { name: cfg.env But the htable.reload command fails: error: 500 - Failed to open htable db connection The Kamailio log reports that it can't connect the db : DEBUG: ctl [../../core/io_wait.h:380]: io_watch_add(): DBG: io_watch_add(0x7f68c74ab300, 10, 3, 0xdc9410), fd_no=1 DEBUG: ctl [io_listener.c:442]: handle_new_connect(): handle_stream read: new connection (1) on /var/run/kamailio//kamailio_ctl DEBUG: <core> [core/sr_module.c:694]: find_mod_export_record(): find_export_record: found <db_bind_api> in module db_mysql [/usr/lib64/kamailio/modules/db_mysql.so] DEBUG: <core> [db.c:209]: db_bind_mod(): using db bind api for db_mysql DEBUG: <core> [db.c:314]: db_do_init2(): connection 0x7f68cc354c10 not found in pool DEBUG: db_mysql [km_my_con.c:98]: db_mysql_new_connection(): opening connection: mysql://xxxx:xxxx@/siprouter ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2 "No such file or directory") ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool ERROR: htable [ht_db.c:92]: ht_db_open_con(): failed to connect to the database My local db is located at /myqdata/mysiprdb/data where is the mysiprdb.sock file.

Re: [SR-Users] problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 09 Aug '18

09 Aug '18

Hello Henning, thanks a lot for your response and explanation. strutils.[c,h] and strcommon.[c,h] are almost the same. So I modified my included header from stcommon[] to strutils as you mentioned. Unfortunately, I surfed sequentially Kamailio version upgrades. Even though, i did not found such hints about this modification. So I have some doubts the called headers and codes from our own module. Hence, I am asking for yor advice. What I am trying to do now is compiliing our module separately under it is own directory so I gain the Shared Object file (.so). Somehow our Module is requring cds, presence and xcap libraries. But the strange thing is that headers from these libraries are #including other headers assuming these included header files are under the same library's directory (but in fact most of the header files are under ../src/core/). For example : Making in cds CC (gcc) [L libser_cds.so.0.1] cds.o In file included from cds.c:2: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/memory.h:125:21: warning: mem/mem.h: No such file or directory /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/memory.h:126:25: warning: mem/shm_mem.h: No such file or directory In file included from cds.c:3: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/sync.h:30:22: warning: locking.h: No such file or directory In file included from cds.c:4: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/logger.h:42:20: error: dprint.h: No such file or directory make[2]: *** [cds.o] Error 1 make[1]: [cds] Error 2 (ignored) Those libraries are delivered with version 5.1.4 itself so i do not think it is a good idea to modify the paths of the included header files to compile my module. because most probably these libraries are needed by standard default modules of kamailio.

problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 09 Aug '18

09 Aug '18

Greetings, i am somehow newbie with Kamailio and trying to migrate from kamailio version 3.0.3 to 5.1.4. Former fellows had developed own modules which needed "strcommon.h" and "strcommon.c". These last two files are not delievered with version 5.1.4. but I copied them under ../src/core/ thinking it would be beneficial. Unfortunately, after make prefix / (and including our own module) all, it seem that several dependencies exist. Especially from header files under ..src/lib/xcap/ and ../src/lib/presence Can somebody tell me how "strcommon.h" and "strcommon.c" where replaced in version 5.1.4 ? Best regards Abdul Aziz

Questions about changes between 5.0.1 and 5.0.7
by Ginhoux, Patrick 08 Aug '18

08 Aug '18

Hi, Following a problem with the kamcmd htable.reload with Kamailio 5.0.1 (see related thread for this), I have upgraded to the 5.0.7 level (with some difficulties due to my specific environment). My server runs the RHEL 7.4 distribution. Now the upgrade is complete, I notice that that are changes not really documented: - The kamailio-perl-5.0.7-1.el7.x86_64.rpm requires to install the mod_perl module that doesn't exist anymore in RHEL 7. It needs to be installed from the EPEL repository - The init script for kamailio has been changed from the old method to the fully compliant method for system unit for RHEL 7 for example: With the 5.0.1 level we have the "/etc/rc.d/init.d/kamailio" With the 5.0.7 level we have now the "/usr/lib/systemd/system/kamailio.service" So my questions/comments are : - Why the mod_perl module is required between 5.0.1 and 5.0.7 (question posted in the attached message) ? - In the previous kamailo init script, I added a condition to start MySQL before kamailio by adding this entry in the script : # Required-Start: $syslog $network $mysqld The new script contains the After command : [Unit] Description=Kamailio (OpenSER) - the Open Source SIP Server After=network.target Should I change the After line with this : After=network.target mysql.target to have the same condition? In all the cases, some documentation must be changed to provide more details. Thanks in advance for the answers. Cordialement. Patrick GINHOUX

RTPEngine UDP receive queue issue
by Alex Balashov 08 Aug '18

08 Aug '18

Hi, We have an RTPEngine that occasionally finds itself in this state of CPU usage: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 25476 root 20 0 2929600 80820 1900 S 156.2 0.1 259:05.54 rtpengine The journal is a dizzying stream of: Aug 06 20:58:47 gw1 rtpengine[25476]: ERR: [1074537188_44545952 port 61666]: Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible It eventually leads to increasing CPU usage and a degeneration of audio quality until RTPEngine is restarted. It would be appreciated if someone could shed some light on the nature of this queue and what we can do about this problem. Is this referring to a netfilter packet forwarding queue, or is it a receive queue of the RTPengine user space control process? Can its size be increased or tweaked with kernel parameters?

I am using Kamailio (5.0.1) and MSILO module for offline messages but I have a problem with users behind NAT. According to module overview, MSILO is forwarding the offline messages to contact address provided in REGISTER request. Is there any way to overcome this and send the messages to the external client IP? Thanks, Michalis Michael

Hi, currenty (the last few days) there has been a spam attack on freenode, #Kamailio is currently full of spam messages, I was wondering if who has operator rights could set the channel to +r (only registered users can send messages) as suggested by freeenode admins The channel usually has only few messages and with all this spam it becomes impossible at all to use it. Greetings, Enrico.

Kamctl Stats Update
by Noah Mehl 07 Aug '18

07 Aug '18

Hey all, I was wondering if the kamctl stats output could be updated to provide a bit more parseable JSON? For instance: # kamctl stats shmem | jq . { "jsonrpc": "2.0", "result": [ "shmem:fragments = 18", "shmem:free_size = 467187808", "shmem:max_used_size = 69694104", "shmem:real_used_size = 69683104", "shmem:total_size = 536870912", "shmem:used_size = 41048984" ], "id": 4300 } I would hope would be more like this: { "jsonrpc":"2.0", "result":[ { "shmem":[ { "fragments":18, "free_size":467187808, "max_used_size":69694104, "real_used_size":69683104, "total_size":536870912, "used_size":41048984 } ] } ], "id":4300 } I apologize in advanced because I don’t have the skillset to contribute such a feature. Thanks! ~Noah

DMQ problems
by Aleksandar Sosic 05 Aug '18

05 Aug '18

Hi, I've set up a dmq server for other kamailio nodes with this parameters: ``` modparam("dmq", "server_address","sip:10.0.0.101:5060") modparam("dmq", "notification_address", "sip:127.0.0.1:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 15) ``` On the kamailio nodes the config is the following: ``` modparam("dmq", "server_address", "sip:10.0.0.x:5060") modparam("dmq", "notification_address", "sip:10.0.0.101:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 15) ``` On the kamailio dmq server I've got this in the logs: ``` 25(41) ERROR: dmq [notification_peer.c:596]: notification_resp_callback_f(): deleting server sip:127.0.0.1:5060 because of failed request 25(41) ERROR: dmq [notification_peer.c:599]: notification_resp_callback_f(): not deleting notification_peer ``` On the kamailio nodes the same thing with the ip of the dmq server: ``` 25(112) ERROR: dmq [notification_peer.c:596]: notification_resp_callback_f(): deleting server sip:10.0.0.101:5060 because of failed request 25(112) ERROR: dmq [notification_peer.c:599]: notification_resp_callback_f(): not deleting notification_peer ``` The request route on the dmq server is simple as this: ``` request_route { if(is_method("KDMQ")){ dmq_handle_message(); } }#end request_route ``` I've tried with some xlog-s inside the if(is_method("KDMQ")) but they don't show up so the dmq_handle_message() is not even executed. I've also tried to bind the dmq server to a different port but with no success on making it work. The dmq.list_nodes shows only the dmq server IP and the current node IP, the IPs of other nodes are not shown: ``` root@proxy-94b6ccf46-t8fx2:/# kamcmd dmq.list_nodes { host: 10.0.0.101 port: 5060 resolved_ip: 10.0.0.101 status: active last_notification: 0 local: 0 } { host: 10.0.0.45 port: 5060 resolved_ip: 10.0.0.45 status: active last_notification: 0 local: 1 } ``` And it's the same on all other kamailio nodes: dmq server ip and local ip. The kamailio version on all the nodes is: 5.2.0~dev6+0~20180616010152.1138+xenial Thanks, -- Aleksandar Sosic mail: alex.sosic(a)evosip.cloud

Security announcement related to Kamailio
by Henning Westerholt 04 Aug '18

04 Aug '18

Hello, I want to highlight that the last stable versions (for the two maintained series: 5.0 and 5.1) include fixes for an security issues that can crash a running instance of Kamailio, therefore it is strongly recommended to upgrade. Details: There exists a security vulnerability in the Kamailio SIP server related to "To" header processing. A specially crafted SIP message with double "To" header and an empty "To" tag causes a segmentation fault and crashes Kamailio. The reason is missing input validation in the "build_res_buf_from_sip_req" core function. If an attacker sends many of this messages this would lead to a Denial of Service of the attacked infrastructure. This is especially critical as no authentication for the remote source is needed. You find all the details including a proof of concept code in the published security announcement in my blog: https://skalatan.de/blog/advisory-hw-2018-05 A CVE report for this issue is going to be created as well in the near future. The issues were found some months ago and were fixed quickly. The code related to the reported issues is rather old and there are no known incidents of exploiting these issues so far. However, once the CVE report becomes public, there could be a higher risk of exploitation. Please address any detailed technical questions related to this to the developer list at sr-dev(a)lists.kamailio.org . In case of confidential remarks related to this or other security issues, please address them to the Kamailio Management. Best regards, Henning Westerholt -- Henning Westerholt https://skalatan.de/blog/

Final reply code is wrong in case of 302 and 486 busy
by Marco Capetta 03 Aug '18

03 Aug '18

Hello, we have a problem of final reply code in case of 302 and then 486 busy. This is our scenario: A, B and C are subscribers. A ----------> Kamailio ----------> B Kamailio <---302---- B Kamailio -----------------------> C Kamailio <---486----------------- C A <---302---- Kamailio Expected behavior: Kamailio should reply to A with 486, as C was busy, and not 302. We have kamailio v5.1.4 In the call to B we set both failure and branch_failure: t_on_failure("failure_route"); t_on_branch_failure("failure_redirect"); in order to handle the 302 redirect per branch with: event_route[tm:branch-failure:failure_redirect] { if($T_reply_code == 301 || $T_reply_code == 302) { do redirect ... } } and the final failure with: failure_route[FAILURE_ROUTE_LOCAL] { do something ... } Since we have 'modparam("tm", "failure_reply_mode", 3)' my expectation is to get the winning reply from the branch of last step. Is there any configuration I'm missing? Since we manage the redirect with a branch-failure, is the winning reply calculated in a different way? Thanks Marco

is_method not matching message type KDMQ breaking DMQ bus. (master branch)
by Asgaroth 02 Aug '18

02 Aug '18

Hi All, I've come across and oddity whereby my is_method("KDMQ") checks are not matching. I'm testing with kamailio master: version: kamailio 5.2.0-dev6 (x86_64/linux) a16272 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a16272 compiled on 15:27:21 Jul 31 2018 with gcc 7.3.1 Sample routing logic: request_route { route("InitialMessageChecks"); exit; } route[InitialMessageChecks] { xlog("L_INFO", "Received message type $rm from $si:$sp on $Ri:$Rp"); if ( is_method("KDMQ") ) { xlog("L_INFO", "KDMQ check passed."); } if ( is_method("OPTIONS") ) { xlog("L_INFO", "OPTIONS check passed."); } if ( is_method("SUBSCRIBE") ) { xlog("L_INFO", "SUBSCRIBE check passed."); } } In the logs I am only receiving the 1st log line in the initial message checks route for message types of KDMQ, eg: INFO: <script>: Received message KDMQ from 1.1.1.1:5060 on 1.1.1.2:5060 INFO: <script>: Received message KDMQ from 1.1.1.3:5060 on 1.1.1.2:5060 I never seem to hit the is_method check log line when the method type is KDMQ. I do see the options/subscribe logs though: INFO: <script>: OPTIONS check passed. INFO: <script>: SUBSCRIBE check passed. nothing for KDMQ. Reason for asking is: this check never matches and breaks the dmq bus: if ( is_method("KDMQ") ) { if ( dmq_is_from_node() ) { dmq_handle_message(); exit; } else { exit; } } Any thoughts, or am I going crazy :) Thanks

Re: [SR-Users] Method Destination Variable
by Duarte Rocha 02 Aug '18

02 Aug '18

Greetings, I thought about that but i wasn't sure it would be safe. But, in this case, the Request-URI domain will be the only place where Kamailio will look to find out the destination right within the dialog right? I'm going the statelless way, so that might be the correct answer. Thanks for your help

get_out_socket(): no socket found
by Ilie Soltanici 02 Aug '18

02 Aug '18

Daniel, Not, those IP are in a different subnet. There is a firewall - running on a different device. Ping and SIP Messages are going very well from 2.2.2.2 to 8.8.8.8. I was able to solve this issue by disabling mhomed and set "listen" external interface with IP address 2.2.2.2 on top in the configuration file. Now, Kamailio is starting without any errors and is registering to the upstream provider, but I just I am wondering if it's possible to specify an outgoing socket for uac module in the configuration file? Thank you.

Method Destination Variable
by Duarte Rocha 01 Aug '18

01 Aug '18

Greetings, I have a Kamailio server set up without Registers. I'm using Dispatcher module for balancing and selecting the destinations. I need to do some changes in the message according to the chosen destination. If it's the first INVITE, after Dispatcher operations, i can do it using $dd or $du variables. However, in later messages, like a BYE, i can't seem to access the method's destination IP. Is there any variable that i'm missing? I've tried $route_uri but it only returns the kamailio's own IP, since it's the only IP in the "Route" header. Thanks in advance, Cheers

RTP Proxy
by Alex Tatham 31 Jul '18

31 Jul '18

Hello everyone, I'm in the process of moving approx. 100 Kamailio/Media Proxy (AG Projects) servers to Kamailio/RTPEngine. I have all the functionality in place and I have a handful of servers in production. I'm trying to monitor the RTP engine (using Munin) and I'm graphing the values returned from the RPC command rtpengine.get_hash_total. This value is slowly increasing over time and I'm trying to find out if this is something I should worry about. I want to make sure that sessions are not being left open and therefore the software will eventually run out of ports. To give some values, if I make 100 calls the call will be around 25 after those calls. >From all other tests I have done including a check through the verbose logs I can see the sessions are being closed at the end of the calls. Can anyone help with this at all or does anyone possibly have any better ideas?

Is anyone having issues with dialog metrics when DMQ is enabled?
by Joel Serrano 30 Jul '18

30 Jul '18

Hi guys, Is anyone having issues gathering active/early dialog metrics from kamailio when DMQ is enabled? I have an open ticket in GH ( https://github.com/kamailio/kamailio/issues/1591) and I'm wondering if this could be happening to anyone else? So far the theory is that the counter goes below 0 and that creates the problem. I'd love to hear from you if you are experiencing this too. If any of you are using Kamailio 5.1 + DMQ and gather active/early dialog metrics using the stats.fetch or stats.get_statistics rpc commands, do you ever get values close to 64BIT ULONG_MAX? (18446744073709551615)?? Thanks! Joel.

DMQ with dialog: KDMQ messages being looped back to the source
by Patrick Murphy 26 Jul '18

26 Jul '18

Hi, I am using Kamailio 5.1.1 with DMQ with the following config (relevant parts) on 2 nodes. Node A: modparam("dialog", "enable_dmq", 1) modparam("dmq", "server_address", "sip:no.de.a.ip:5060") modparam("dmq", "notification_address", "sip:myvoip.local") modparam("dmq", "multi_notify", 1) Node B: modparam("dialog", "enable_dmq", 1) modparam("dmq", "server_address", "sip:no.de.b.ip:5060") modparam("dmq", "notification_address", "sip:myvoip.local") modparam("dmq", "multi_notify", 1) "myvoip.local" is a DNS A record that resolves to both the IPs of A and B. I have the dmq_handle_message(); called if method is of type "KDMQ" in the request_route. Now, in order to test it, I only sent a few calls only on node A. KDMQ messages flowed to node B and dialog state replicated. But I noticed, node B was randomly sending one of the KDMQ dialog messages back to A and receiving a 500 "Server Internal Error" back from node A... (for a subset of those calls, not all). Why would this be the case when the nodes correctly recognize their local status by the "local: 1" set as seen from dmq.list_nodes Anyone else experienced this? What could I be doing wrong? Thanks, Pat.

FreeSWITCH and OpenSIPS for a Pure SIP Video, Chat and Conference Service, ClueCon Presentation Slides
by Giovanni Maruzzelli 25 Jul '18

25 Jul '18

Hello fellow RTCers, just finished presenting about scaling videoconferencing, chat and moderation/direction controls in SIP, with web clients, deskphones, smartphone apps, server push (google fcm) via cordova and SIP.js at www.cluecon.com. Here's the slides of my presentation: http://178.79.181.125/Maruzzelli_FreeSWITCH_OpenSIPS_WebRTC_Pure_SIP_Video_… or, shorter, http://178.79.181.125/Maruzzelli_ClueCon_2018.pdf >From ClueCon blurb: FreeSWITCH and OpenSIPS for a Pure SIP Video, Chat and Conference Service On top of traditional SIP deskphones and softphones, WebRTC let us extend the reach of SIP to all browsers, and to smartphone apps that wake up with a server push. OpenSIPS has superb SIP and WebRTC support and can protect, balance and scale FreeSWITCH insuperable conferencing, video MCU, media switching/mixing, SIP SIMPLE message processing capabilities. We will see how to build and implement such a complete platform, touching both on servers and on clients. Hint: SIMPLE, the SIP Instant Messaging Protocol, can be leveraged to transport statuses, commands and chats between participants and administrators of SIP audio/video calls/conferences.

Error when using http_async_client $http_query_id var

messages dumped in wrong order sometime
by Philip Kucheev 23 Jul '18

23 Jul '18

Hello there! Using kamailio 5.0.1 and msilo module for storing offline messages I noticed that sometimes, especially when a big number of messages dumping for one user, some of them can arrive to receiver in wrong order. Lets say we have 20 messages and the order of receiving could be next 1..18..17..19..20. That could be a reason of that ? Thanks, Philip

Forwarding to backup server
by Pali Rohár 23 Jul '18

23 Jul '18

Hello, can somebody help me how to configure Kamailio to route/forward requests to different (backup) server when Kamailio itself is not able to deliver them? I have working SIP gateway (on different host/port) which deliver received SIP messages to XMPP network and I want to achieve: Kamailio should try to send SIP messages directly to foreign SIP domains and when it fails (e.g. user not available or foreign SIP is not running), then forward message to that my SIP <--> XMPP gateway which will try to deliver it via XMPP. I guess that Kamailio should be able to configure for such custom routing/forwarding but I have not figured yet how to do it. I'm using Kamailio 4.4 with slightly modified default kamailio.cfg config. -- Pali Rohár pali.rohar(a)gmail.com

Hello Ali, ACK is sent by UAC to the Contact which is received in OK from UAS. So from my point of view you need to fix that Contact in OK on your proxy. My NATDETECT looks like: if (nat_uac_test("19")) { fix_nated_contact(); } I call it for requests and responses. Best regards.

Hi, I have a kamailio v5.0 setup where cdrs are enabled using acc module. Is there a way to enable / disable cdrs on per call basis in kamailio script? For example i want to allow cdrs only for offnet calls and disable them for onnet calls? May be a dialog flag configurable in module parameters to signal acc module whether or not to generate cdr for current dialog at the end of call?

Hello I have faced when case when private var defined as $var(json_request) is share between different SIP messages. In my case first time this var is used from registration processing route. Then var with same name is used PUBLISH messge processing. And i be able to this value defined from registration processing. I expecting that vars is not shared between threads and message handling routes for var defined as $var(name). Is that not true? How i can prevent race condition between different message processing routes when two thread simultaneously change same variable? Sergey

The problem of get_aor_hash function
by tyd 20 Jul '18

20 Jul '18

Dear all, I'm trying Kamailio 5.1.4 and IMS module. When registering to Kamailio IMS using the same ip and port for 30 users (different contact user part), the P-CSCF get the same hash number and aor value. The function get_aor_hash(_d, &_ci->via_host, _ci->via_port, _ci->via_prot) in ims_usrloc_pcscf pcontact.c seems the problem. Because hashing with host, port, prot will get the same hash value. Anyone can help this ?

Locking htable entries
by Alex Balashov 19 Jul '18

19 Jul '18

Hi, Sorry if this question has been answered before, but I'm rather puzzled as to the intent behind sht_lock() / sht_unlock(). Presumably, "thread"-safe / shm mutex locking is already implemented in htable query and mutation operations, otherwise htable would be unusable in a route script context. So what is the purpose of this higher-level lock? Is it to create a way to block config script execution in multiple processes as to serialise operations? Why would one want to do this under any ordinary circumstances? Perhaps it is a failure of my imagination...

executing python routine on demand
by Walter Martín Villalba 18 Jul '18

18 Jul '18

Hello, TL;DR How can I execute a routine in my Kamailio python module (kamailio_python.py) on demand? For example, using kamcmd from the command line. I know you can execute *app_python.reload *but I don't need to reload the whole python module, and furthermore, docs for this call say it's unstable and can even crash your kamailio instance. So my goal is to execute one single python routine on demand. https://www.kamailio.org/docs/modules/5.1.x/modules/app_python.html#app_pyt… Full explanation: I'm currently implementing OIDC token authentication for Kamailio. I have a python routine that extracts the token from a custom SIP header, and validates the token as per the OIDC spec (I'm using pyjwt plus other custom checks for this). In order to do offline validation of the token, you need the Identity Provider (IdP) Server's certificate, which I get in advance and cache in a local file on my Kamailio server. I also have an external python script which I can run to get the latest certificate from the IdP server and update it locally. The part I'm missing is how to tell Kamailio to reload the value of the certificate from the local cache, WITHOUT stopping kamailio or interrupting any sessions. This is needed in case the certificate is updated (e.g. due to expiration or compromise) on the IdP server; if you don't update it so that Kamailio can use the latest one, all token verification will fail (tokens signed by IdP server using latest private key corresponding to latest certificate, but Kamailio trying to validate the signature using the public key extracted from previous certificate -- this results in a signature error, as Kamailio needs to be using the public key corresponding to the private one that was used to sign the token). By being able to execute one single python routine on demand (e.g. using kamcmd), I can tell Kamailio to reload the certificate value from the local cache, which I just updated by running my other (external and unrelated to Kamailio software) python script. Hope this makes sense, and hopefully I can get some tips on how to achieve this. Thanks, Martín.

in-dialog requests
by Ali Taher 18 Jul '18

18 Jul '18

Hello, I'm using Kamailio as a proxy behind freeswitch to alter some packets (183 packets precisely). Here is my scenario: (---Customer---) --> ((port 5065)---Kamailio---) --> ((port5060)---Freeswitch---) --> (---Supplier---) Here is my request route : route{ if (is_method("INVITE")) { xlog("L_INFO","INSIDE request route $si \n"); insert_hf("X-AUTH-IP: $si\r\n"); } route(FWD); } reply_route { #xlog("L_INFO","INSDE reply \n"); if (status == "183") { change_reply_status(180, "Ringing"); exit; } } route[FWD] { #xlog("L_INFO","INSIDE FWD \n"); forward(X.X.X.X,5060); } Where X.X.X.X is the Freeswitch IP This script is working normally as long as the customer is sending the requests(INVITE,BYE,ACK,CANCEL..) . But when the supplier or freeswitch initiated the request , above script causes loop where the packet is bounced between kamailio and freeswitch. As I know , loose_route is used to handle such requests , but I'm not sure how to forward these packets to the customer after receiving them from freeswitch. I'm not sure also if what's I'm doing is statefull or stateless. Any help is appreciated. Thanks, Ali Taher

Kamailio dialog presence (BLF)
by Michal Škuta 18 Jul '18

18 Jul '18

Hello, I am trying make presence module work with Kamailio. Right now I am testing these modules: presence, presence_xml, presence_dialoginfo, pua and pua_dialoginfo. I had some success, the BLF is working only when the monitored extension is calling. When the monitored extension is calling, then the BLF changes its color (red). After end of the call the BLF changes color to green. My problem is when a User comes on-line then it sends SUBSCRIBE with *Event: dialog* and don't get notified of its subscribers state and BLF is not changed. I found similar problem in this mail list : https://lists.kamailio.org/pipermail/sr-users/2017-March/096314.html But is not working for me. Second question is about BLF and offline state. I can not found anything in RFC, there is no offline state, no way to turn off the BLF lamp from green to OFF. I found only this pdf from grandstream: http://www.grandstream.com/sites/default/files/Resources/GXP21x0_Eventlist_… mentioning offline state on page 8. Does anyone have experience with it?

SIP re-invite Packets
by Ali Taher 18 Jul '18

18 Jul '18

Hello, I'm using below routing logic to change the 183 reply to 180 and send it back to the origination. Noting that Kamailio is listening on 5065. route{ if (is_method("INVITE")) { xlog("L_INFO","INSIDE request route $si \n"); insert_hf("X-AUTH-IP: $si\r\n"); } route(FWD); } reply_route { #xlog("L_INFO","INSDE reply \n"); if (status == "183") { change_reply_status(180, "Ringing"); exit; } } route[FWD] { #xlog("L_INFO","INSIDE FWD \n"); forward(x.x.x.x,5060); } Below is the scenario , where the customer is sending packets to Kamailio , and Kamailio is forwarding them the supplier (with IP x.x.x.x) , then the supplier reply back to kamailio and kamailio relay the reply to the customer ----Customer---- --> ----Kamailio ---> ---Supplier--- I have a case where the supplier sends in some cases an in-dialog invite (Re-Invite) , which is considered I think as SIP-Request and thus as per above routing logic , kamailio is sending it back to the supplier , yet I need to send it to the customer. How can I solve this issue? Thanks Ali Taher

ACK Cseq incrases after 404 on uac_auth()
by Yuriy Gorlichenko 17 Jul '18

17 Jul '18

Hi. I found some additional scenario when kamailio works incorrect with ACK Cseq after succesfull auth with uac_auth but unsuccesfull call: 1.Caller via kamailio as proxy (Cseq 1) 2.Kamailio resends call to provider with Auth method (Cseq 1) 3. Provider answers 401/407 (Cseq 1) 4. Kamailio inrases Cseq and sends invite with credentians (dialog track_cseq_updates = 1, uac_auth()) (Cseq 2) 5. Provider says - 404. not found (Cseq 2) 6. Kamailio resends INVITE to another server (lets say VM). It contans not tracked yet Cseq (Cseq 1) 7. VM server says 200 (Cseq 1) 8. Kamailio resends 200 to the caller (Сseq 1) 9. Caller says ACK (Cseq 1) 10. Kamailio incrases CSeq of ACK and resends t VM server (Сseq 2) So in this case kamialio tries to track Sceq because thining that this ACK belongs to the dialog that was made to the auth server So as I see here is a misunderstanding on the dialog module Any suggestions how to avoid it or exclude resent INVITE from the dialog module tracking?

RTPEngine serial forking with early media
by Alex Balashov 16 Jul '18

16 Jul '18

Hi, I've got a scenario where call branch #1 goes to an in-call announcement server; the message is played out via unidirectional early media (183+SDP), then that branch is disposed of with a 503. A subsequent call then goes out to the real SIP provider that will ultimately answer the call. There's some trouble handling this with RTPEngine: Two subsequent calls to rtpengine_offer() in a normal request route context will result in two SDP message lumps concatenated in the second INVITE (to the provider). This can be fixed by putting the rtpengine_offer() invocations into branch routes. However, the next problem is that then the identical offer goes to the second callee with no regard for RTPEngine's internal state, so RTPEngine ends up transmitting from a different port to the one that is declared in the SDP offer, requiring NAT latching from the provider to achieve proper symmetry in the return stream. This can be fixed with: rtpengine_offer("replace-origin replace-session-connection ICE=remove via-branch=1 internal external"); And in the reply handling: rtpengine_answer("replace-origin replace-session-connection ICE=remove via-branch=2"); An alternative to using via-branch[1] is to simply delete the call before initiating branch #2: rtpengine_delete("delete-delay=0"); rtpengine_offer("replace-origin replace-session-connection ICE=remove internal external"); However, both of these lead to the problem that caller receives two distinct SDP answers on the respective branches. I am not sure offhand whether this is a protocol semantics violation. On the one hand, RFC 3261 § 13.2.1 ("Creating the Initial INVITE") says: If the initial offer is in an INVITE, the answer MUST be in a reliable non-failure message from UAS back to UAC which is correlated to that INVITE. For this specification, that is only the final 2xx response to that INVITE. That same exact answer MAY also be placed in any provisional responses sent prior to the answer. The UAC MUST treat the first session description it receives as the answer, and MUST ignore any session descriptions in subsequent responses to the initial INVITE. So, I always understood that the first answer is the final answer, absent a session-updating request cycle. On the other hand, RFC 3960 ("Early Media and Ringing Tone Generation in the Session Initiation Protocol (SIP)") Section 4 says: The application server model consists of having the UAS behave as an application server to establish early media sessions with the UAC. The UAC indicates support for the early-session disposition type (defined in [2]) using the early-session option tag. This way, UASs know that they can keep offer/answer exchanges for early media (early-session disposition type) separate from regular media (session disposition type). I take this, along with RFC 3959 Section 3, to imply an amendment to 3261 § 13.2.1, but I'm not sure. Regardless, I'm not convinced all UAs will handle this situation. So, what I would most prefer is a means of recycling the same answer port on the "back" side of RTPEngine while pivoting it on the front across branches/multiple offers. Is that possible? If so, how can it be achieved?

Encapsulate and de-encapsulate SIP traffic
by William Phillips 16 Jul '18

16 Jul '18

I have a need to encapsulate SIP traffic depending on destination and obviously de-encapsulate traffic incoming from those destinations. The approach to dealing with outbound SIP traffic seems pretty straight forward, I create an appropriate routing block that determines if I need to encap the SIP message, if I do, I forward it off to my module. The incoming traffic isn't particularly complicated, I'm just not 100% sure on the way to give that de-encapsulated SIP message back to kamailio to be processed. It looks like I can achieve this using the TM module with the uac_req_t struct and tm_bind.request but I really only see it used for SIP text messages in modules like XMPP and SMS. Is this the appropriate approach to achieve what I need? Will

Hi, I m using cent-os 6.2, kamailio-5.1.2 and openims-hss. I am using rtpengine to relay voice, but I am unable to send files or chat messages using it. I looked at rtpengine logs, it was saying unknown codec for chat and file-transfer requests. Then, I thought of using Kamailio msrp , tried but no success. Does current Kamailio IMS support file transfer? If so, please give me suggestions on doing it. -- With Best Regards, Ashok Kumar.

rtpengine/kamailio teardown method
by Abdoul Osséni 16 Jul '18

16 Jul '18

Hello all, There are some rtpengine parameters that permit to send an RPC command to kamailio in order to terminate a dialog. - timeout = xx - b2b-url = http://xxxx:xx/RPC - xmlrpc-format = 1 Each rpc command sent to Kamailio exited with status 256. By checking the code of rtpengine, I see rtpengine seems to use "teardown" method. I think Kamailio does not know this method. Can you help me please ?

UAC register
by Ben Hood 12 Jul '18

12 Jul '18

Hi, I’m wondering if there is a flag somewhere in the UAC module config that prevents remote registration from happening. It looks like I’ve loaded the uacreg table but I can’t see any REGISTER methods being sent from Kamailio to the remote peer. The remote registrants are loaded using this config: listen=udp:172.16.176.150:5060 loadmodule "db_postgres.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "cfg_rpc.so" loadmodule "counters.so" loadmodule "uac.so" modparam("uac", "reg_db_url", DBURL) modparam("uac", "reg_contact_addr", “172.16.176.150:5060") modparam("uac", "reg_db_table", "uacreg") modparam("uac", "reg_timer_interval", 10) modparam("uac", "reg_retry_interval", 10) request_route { route(RELAY); } route[RELAY] { t_on_reply("MANAGE_REPLY"); if (!t_relay()) { sl_reply_error(); } exit; } And it looks like this has been consumed by Kamailio: $ kamcmd uac.reg_dump { l_uuid: 2cc6776d-61ed-4ea1-a3ae-055f89bd4d3f l_username: 126231943099723776 l_domain: 172.16.176.150 r_username: 1000 r_domain: 172.16.176.129 realm: 172.16.176.129 auth_username: 1000 auth_password: password auth_proxy: sip:172.16.176.129:5080 expires: 0 flags: 0 diff_expires: -1531235076 timer_expires: 0 reg_init: 1531234841 reg_delay: 0 } Doing a refresh successfully reloads the uacreg data $ kamcmd uac.reg_refresh 2cc6776d-61ed-4ea1-a3ae-055f89bd4d3f I can get Kamailio to forward an OPTIONS message to the remote peer () to verify network connectivity, e.g. : $ru = "sip:1000@172.16.176.129:5080"; $fs = "udp:172.16.176.150:5060"; But Kamailio does not appear to generate REGISTER messages either after first boot or as a result of the manual refresh. This is using an instance of Kamailio 5.0.1. Should I try with a newer version? Is there a way to get extra debugging of the uac module? If I increase the debug verbosity, I get quite granular detail for the DB traffic, but the uac module doesn’t appear to emit much diagnostics. Many thanks, Ben

Kamailio, forking and multiple answer
by Marino Mileti 10 Jul '18

10 Jul '18

Hi guys, i've a Kamailio with forking scenario using addbranch technique.Now I've a problem; i know it's very very very rare but it could be possible so it's better for me to find a solution. A -> B,C,D in forking parallel mode, so B C and D rings simultaneulsy. What is happen if B anser the call, and at the same time C decline the call?It seems that, using my cfg scripts, C sends DECLINE but this message never arrive to A because it receives a 200OK of B. How I can prevent this? I would like that if DECLINE is the first message, all other answers will be ignored (first answer win). Any help or comment? ThanksMarino

TLS CRL configuration
by Amarnath Kanchivanam 10 Jul '18

10 Jul '18

Hi All, I'm trying to configured kamailio as TLS server with below configuration (tls.cfg) and TLS server is started successfully. [server:default] method = TLSv1+ verify_certificate = yes require_certificate = yes private_key = ./sip/server.key certificate = ./sip/server.crt ca_list = ./bundle.crt crl = ./sip_crl.pem verify_depth = 9 [client:default] verify_certificate = no require_certificate = no TLS connection works fine. Later i have updated the sip_crl.pem with server certificate revoked details and performed tls.reload command to load the latest update. After this I expect any TLS client trying to establish TLS connection should fail, as the client and server certificates are signed by same authority and server certificate is revoked. But the clients are able to establish TLS connection without any errors. I'm not getting any traces to confirm CRL validation has been performed before accepting the TLS connection. Any advice would be help to proceed with evaluating CRL functionality. -Amar

Delay in 100 Trying response for INVITE when the load is 70 INVITE's per sec
by vivek＠advaitamtech.com 09 Jul '18

09 Jul '18

Hi All, When we are using the kamailio to handle around 70 INVITE's per second, kamailio is sending 100 Trying with the delay of around 3-4sec for few INVITE's. How can I reduce the delay in 100 Trying? Also, I tried increasing the number of threads for SIP routing processes. This doesnt seem to help. Also tried "modparam("tm", "auto_inv_100", 0)" . This is not working. Please help. Thank you, Vivek.

Hello, In RTPEngine recording-daemon, I enabled "forward-to" option to unix_socket. All things work right, I got metadata at first, then media packets (RTP-UDP-IP). The metadata for each calls is received just at first packet, but i want to know, if i have more than one concurrent active call in RTPEngine, How can i distinct which media packet was from which call?

RFC: database unsigned number types
by Daniel-Constantin Mierla 07 Jul '18

07 Jul '18

Hello, starting here a discussion about an issue with the database API and signed/unsigned number type to see how to address it. So far, the database API supported only signed types for numbers, respectively DB1_INT (int in c) and DB1_BIGINT (long long in c). However, many database table columns are defined as UNSIGNED INT or UNSIGNED BIGINT. The database connector modules are mapping UNSIGED values retrieved from database over signed fields in DB API structure. The other way around is done as well: signed values are the inserted in the unsigned columns. There is no issue if the value in C is a positive number, however, if the value goes over MAX_UINT/2 (over 2147483647), it becomes negative and inserting the value in database results in an exception and 0 being stored instead. So far, I guess the issue was rarely exposed, if at all, because no report on it, even these data types for DB1 are since the SER project was started in 2001. As I looked at database definition schema, most of unsigned columns are for internal flags or ids (e.g., lcr_id), where I guess no large values were used or needed so far. However, it can bite at any time and needs to be addressed. So far, two solutions come in mind: 1) drop using UNSIGNED INT for those db columns, use only INT and do unsigned cast in the C code when reading and cast to int when writing. 2) update the db connector modules to support unsigned types -- I added support for them in DB API, but each db_* module has to be updated. The also each module that uses UNSIGNED DB columns must be updated 1) should be simpler, 2) more work but better in long term Any other ideas? Which of the options you prefer to go for? Not to forget: somehow related, probably we have to switch from int to long for PV number values, otherwise timestamp variables can go negative once unix timestamp approaches MAX_UINT/2 (still plenty of time, but should not be delayed for long ...).

rtpengine installation dependencies

Also, If someone can help me how to resolve dependency for libbcg729-dev too. Any pointer or hint or link to some installation guide would be more than welcome. Br, Aqs.

Video call recording and mobile push notifications
by Jeremy Renner 05 Jul '18

05 Jul '18

Hi, I would like to setup up my SIP server / PBX for my business, now we have some candidates: 1. Open source solution: - Asterisk PBX, - Freeswitch PBX - Kamailio - OpenSIPS 2. Business solution: - Brekeke PBX(https://www.brekeke.com - Vodia PBX(https://www.vodia.com) - 3CX PBX(https://www.3cx.com) - PortSIP PBX(https://www.portsip.com/portsip-pbx) *Below features are mandatory for our project:* - Video call recording (For the finance industry, the video recording is necessary) - Push notifications for mobile app - Multi-tenant support - Both Linux and Windows support (at 1st stage, we would like to run it on Windows server and migrate it to Linux server in the future if users increased), the Linux support is required, the Windows support is preferred. We have some questions: 1. Does the the Kamailio can works as a PBX ? 2. If yes, does the Kamailio support push notifications and video recording ? 3. Does the Kamailio can works for Multi-tenant ? 4. Does Kamailio support Windows ? So far according to our research, with the business solution: - The Vodia PBX, PortSIP PBX and brrekeke all are support Multi-tenant, the 3CX is not. - The 3CX and PortSIP support push notifications, - The PortSIP also provide client SDK, with 3CX we only see the 3CX provide client apps, does 3CX has client SDK provided ? - It's seems all these PBX are support video recording ? - The PortSIP PBX and 3CX both support Linux. Please help me to make the decision, base on your experiences, which one (open source or business solution) is good to us ? I'm really new to VoIP... Thanks in advance. Best regards,

Re-write From URI Domain ($fd) with source IP or relayed message
by Marrold 04 Jul '18

04 Jul '18

Hi All, For interoperability reasons I need to re-write the From URI Domain ($fd) in requests proxied by Kamailio to the source IP (socket) that Kamailio will send them via. I have experimented with onsend_route and can successfully discover the snd_ip, however it seems I am unable to rewrite the $fd, presumably because I am too late in the logic. Is this possible? I can hardcode IPs if required but would rather keep it dynamic if I can. Thanks in advance, Matthew

Kamailio Anycast
by Mike Little 03 Jul '18

03 Jul '18

Hello, Sorry if this has already been answered but can Kamailio be configured to support clustering and use Anycast? We are looking to use Kamailio as a front end to Asterisk as the registar and presence server. If this is supported, are there any documents that explain how to configure this type of setup? Thanks!

IMS usage of Kamailio
by Akib Sayyed 03 Jul '18

03 Jul '18

Dear All I am willing to try Kamailio as IMS. before i try i would like to know following points - in Kamailio i see diameter support and authentication I-CSCF, P-CSCF, S-CSCF charging, QOS, ISC implemented but what about TAS do i need TAS seperately - I see that there is HOW-TO wiki , in how to wiki you are using FHoSS as HSS , can we use commercial/any other hss (afaik its using diameter so any HSS will do)? - Is there any configuration online available kamailio as IMS? - Are all IMS modules of Kamailio can be installed on one server or need each module on same machine (i am using IMS only for testing 1 or 2 calls at a time)

Having trouble getting presence working with Polycom VVX phones
by Justin Foley 03 Jul '18

03 Jul '18

Hey everyone. I've set up a kamailio server on a local dev box and running the phones on the same subnet as it to avoid any NAT issues. Seems to work fine, phones register & can call eachother and hear voice but the issue I'm running into is I can't seem to get presence to work. I've enabled it in the kamailio.cfg file with #!WITH_PRESENCE but if I go into "do not disturb" or try to call on phone1, it's not indicated on phone2. Also running ngrep on port 5060, I'm not seeing the anything regarding presence being sent over the SIP protocol.

Hi community, So I'm running 4.1.5 Kam version and I wanted to print out $rs variable. It printed out <null> right after the 183 session. Should it print something?

Auth and default kami config
by yu＠yu-boot.ru 03 Jul '18

03 Jul '18

Hello. Have a question on auth and default kamailio.cfg. Default behavior of kamailio on auth is: Auth initial requests, delete auth headers before forwarding to next hop. In-dialog requests are forwarded "as-is" so all auth related info is propagated to uplinks or just another Kami users. How should it be done correctly or "kamailio-way"? As for now, I just delete auth headers for all in-dialog requests, but I'm not sure it is correct. I looked how it works on softswitches like Yate. Registers and initial Invites are authenticated, ACK is not authenticated, but all other requests like reINVITE and BYE are. How is should be done? Thanks. -- sent from myMail for Android

kamailio with kannel
by eyas barhouk 02 Jul '18

02 Jul '18

hello dears , i'm trying to use "http_client" module to post SMS from kamailio to kannel using the following configuration : ....... modparam("http_client", "httpcon", "kannel=>http://username:password@127.0.0.1:443") .......... ......... http_connect("kannel","cgi-bin/sendsms?user=username&pass=password&charset=utf-16&coding=2&from=$avp(from)&to=$avp(to)&text=$(avp(text){s.escape.user})","$var(result)"); ....... And this test success for English characters & phrases, but when i'm trying to send Arabic or Chinese characters it only success if the content of the SMS only has one word. in other-word i mean when i'm trying to send more than one Arabic word with a space between each word it reply with HTTP error code 400. so do you have any ideas about this problem ??

Should I ignore Route header in ACK?
by Yuriy Gorlichenko 02 Jul '18

02 Jul '18

Hi I know that this is not question too much close to the kamialio users but mostly losed to the RFC specifiacations but this community looks like pretty much close to it that is why I want to ask this question here, that's why sorry and thanks for help in this question: I have a situation when provider sends me 200 response with Request-Route header and changed contact header: Means response comes from 1.1.1.1:5060 Request-Route contains: 1.1.1.1:5060 But Contact contains: 1.1.1.1:5061 My ACK (handled by kamailio) goes to the 1.1.1.1:5060 as it setted up at the Route Hedaer of ACK (because of Request-Route) but provider says me that i should use Contact for the ACK I was surprised because of https://tools.ietf.org/html/rfc3261#section-12.2.1.1 and https://tools.ietf.org/html/rfc3261#section-8.1.2 Says that I should use Route header for reaching destination But I was surprised second time when tested this scenario with FreeSwitch and another softphone (as UA) because of it both sends ACK to the based on Contact address and ignores Route I just wanna ask if I missed some scenario in the RFC when it is described to ignore Route header for the UA (I know that I use kamailio on my case as proxy server but should understand finally who should make changes with packet handling) Thanks one more time for the resonses and sorry one more time for the goal of this question that belongs to the kamailio just partially

Fwd: Video call recording and mobile push notifications
by Jeremy Renner 01 Jul '18

01 Jul '18

Hi, I would like to setup up my SIP server / PBX for my business, now we have some candidates: 1. Open source solution: - Asterisk PBX, - Freeswitch PBX - Kamailio - OpenSIPS 2. Business solution: - Brekeke PBX(https://www.brekeke.com - Vodia PBX(https://www.vodia.com) - 3CX PBX(https://www.3cx.com) - PortSIP PBX(https://www.portsip.com/portsip-pbx) *Below features are mandatory for our project:* - Video call recording (For the finance industry, the video recording is necessary) - Push notifications for mobile app - Multi-tenant support - Both Linux and Windows support (at 1st stage, we would like to run it on Windows server and migrate it to Linux server in the future if users increased), the Linux support is required, the Windows support is preferred. We have some questions: 1. Does the the Kamailio can works as a PBX ? 2. If yes, does the Kamailio support push notifications and video recording ? 3. Does the Kamailio can works for Multi-tenant ? 4. Does Kamailio support Windows ? So far according to our research, with the business solution: - The Vodia PBX, PortSIP PBX and brrekeke all are support Multi-tenant, the 3CX is not. - The 3CX and PortSIP support push notifications, - The PortSIP also provide client SDK, with 3CX we only see the 3CX provide client apps, does 3CX has client SDK provided ? - It's seems all these PBX are support video recording ? - The PortSIP PBX and 3CX both support Linux. Please help me to make the decision, base on your experiences, which one (open source or business solution) is good to us ? I'm really new to VoIP... Thanks in advance. Best regards,

linphone & presence_xml ERROR
by Pali Rohár 01 Jul '18

01 Jul '18

Hi! I'm using linphone 3.6.1 as SIP client and Kamailio 4.4.4 as proxy server and registrar. And every time I try to change online status (presence) in linphone client, I see following error messages in kamailio server log: ERROR: presence_xml [add_events.c:167]: xml_publ_handl(): bad body format ERROR: presence [publish.c:443]: handle_publish(): in event specific publish handling ERROR: tm [t_reply.c:533]: _reply_light(): ERROR: _reply_light: can't generate 500 reply when a final 415 was sent out ERROR: sl [sl.c:269]: send_reply(): failed to reply stateful (tm) ERROR: presence [utils_func.c:146]: send_error_reply(): sending 500 Server Internal Error reply ERROR: presence [publish.c:492]: handle_publish(): failed to send error reply So it looks like kamailio is not able to parse presence change which is linphone doing.

Maybe it helps you. Any idea why kamailio refuse presence update and reports those error into error log? Or is there any special setting which is needed for linphone or other SIP clients for online status / presence support? -- Pali Rohár pali.rohar(a)gmail.com

dovecot authentication
by Pali Rohár 30 Jun '18

30 Jun '18

Hi! Is there any module or configuration how to use dovecot SASL authentication in Kamailio? Dovecot exports unix socket (or tcp on localhost) for authentication service and lot of server applications can be configured to use it (e.g. postfix, prosody, ...) to have one central place of user and authentication database. It supports also strong authentication schemas like SCRAM-SHA, but also plain text password or DIGEST-MD5. In SIP is used DIGEST-MD5 therefore it could be suitable also for SIP and Kamailio. -- Pali Rohár pali.rohar(a)gmail.com

Relevant development links
by Amauri Oliveira 28 Jun '18

28 Jun '18

Hello. I'm new to Kamailio perhaps I've seen it in actions at AirBNB. I'm starting the journey as a new developer who wants to grab Kamailio and build something. I would like to check if you could provide the most relevant links for a beginner also with some samples. I noticed the abundance of modules perhaps I would like to see what people are doing with it. Best Regards, Amauri.

Fwd: Understanding is_first_hop() and how it handles in-dialog replies
by Joel Serrano 28 Jun '18

28 Jun '18

Hi guys, I'm having an issue which I have narrowed down to is_first_hop(), I can apply a workaround, but I don't know if I'm doing it correctly or if my problem is caused by misconfiguration of anything. Let's say we have the following flow: Client (NAT) TLS -> Kamailio1 (only Public IP) UDP -> Kamailio2 (only Public IP) UDP -> FreeSWITCH (only Public IP). Regarding this setup, let's focus only on Kamailio1. And for the sake of a clear example, I have done a little draw.io diagram: >From the above flow, let's stick to the *200 OK* that Kam1 is going to receive from Kam2. (marked in *blue* in the screenshot). First 200 OK (replying to initial INVITE): SIP/2.0 200 OK Via: SIP/2.0/UDP KAM1_PUB_IP;rport=5060;branch=z9hG4bK1e2b. e1307b519c9b5f0015343e13f35aeace.0;i=3 Via: SIP/2.0/TLS [2607:fb90:489b:6e13:85f8:596b:b86b:c831]:54744; received=172.58.17.149;branch=z9hG4bK.jmXSnh-7x;rpo =43842 Record-Route: <sip:KAM2_PUB_IP;lr=on;ftag=7vidaJ3Hw;did=36e.d441> Record-Route: <sip:KAM1_PUB_IP;r2=on;lr=on;ftag=7vidaJ3Hw;did=36e.a792; nat=yes> Record-Route: <sip:KAM1_PUB_FQDN:443;transport=tls;r2=on;lr=on; ftag=7vidaJ3Hw;did=36e.a792;nat=yes> From: "Joel Test 1" <sip:8bd2a0aba14541789bb7269800646458@MY_DOMAIN >;tag=7vidaJ3Hw To: "Joel Test 2" <sip:e78f2617b0d345d3bdb7b6780ece903c@MY_DOMAIN>;tag= vceg6N0m5ypHa Call-ID: 3ezoQGF1kp CSeq: 21 INVITE Contact: <sip:e78f2617b0d345d3bdb7b6780ece903c@FS_PUB_IP:6061;transport=udp> User-Agent: TP MEDIA 2.0 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Allow-Events: talk, hold, conference, refer Content-Type: application/sdp Content-Disposition: session Content-Length: 358 Remote-Party-ID: "e78f2617b0d345d3bdb7b6780ece903c" <sip: e78f2617b0d345d3bdb7b6780ece903c@MY_DOMAIN>;party=calling; privacy=off;screen=no v=0 o=TP 1529576021 1529576022 IN IP4 FS_PUB_IP s=TP c=IN IP4 FS_PUB_IP t=0 0 m=audio 25484 RTP/AVP 96 101 a=rtpmap:96 opus/48000/2 a=fmtp:96 useinbandfec=1; maxplaybackrate=8000; sprop-maxcapturerate=8000 a=rtpmap:101 telephone-event/48000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=rtcp:25485 IN IP4 FS_PUB_IP Second 200 OK (replying to in-dialog INVITE with updated SDP): SIP/2.0 200 OK Via: SIP/2.0/UDP KAM1_PUB_IP;rport=5060;branch=z9hG4bKed2b. 0006a6a159e800129a62b4415fdd64e6.0;i=7 Via: SIP/2.0/TLS 192.168.30.63:54752;received=A.B.C.D;branch=z9hG4bK. iKO2iYIgK;rport=27819 From: "Joel Test 1" <sip:8bd2a0aba14541789bb7269800646458@MY_DOMAIN >;tag=7vidaJ3Hw To: "Joel Test 2" <sip:e78f2617b0d345d3bdb7b6780ece903c@MY_DOMAIN>;tag= vceg6N0m5ypHa Call-ID: 3ezoQGF1kp CSeq: 22 INVITE Contact: <sip:e78f2617b0d345d3bdb7b6780ece903c@FS_PUB_IP:6061;transport=udp> User-Agent: TP MEDIA 2.0 Accept: application/sdp Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Content-Type: application/sdp Content-Disposition: session Content-Length: 358 v=0 o=TP 1529576021 1529576022 IN IP4 FS_PUB_IP s=TP c=IN IP4 FS_PUB_IP t=0 0 m=audio 25484 RTP/AVP 96 101 a=rtpmap:96 opus/48000/2 a=fmtp:96 useinbandfec=1; maxplaybackrate=8000; sprop-maxcapturerate=8000 a=rtpmap:101 telephone-event/48000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=rtcp:25485 IN IP4 FS_PUB_IP Now here comes the problem, I have the following in my kam1 config: route[NATMANAGE] { ... if (is_reply()) { if (isbflagset(FLB_NATB)) { if (is_first_hop()) { fix_nated_contact(); } } } ... } So, on the first 200 OK, when it reaches that part of the config: 1- is_reply() -> OK 2- isbflagset(FLB_NATB) -> OK (because on the initial request NAT was detected blablabla....) 3- is_first_hop() -> FAIL fix_nated_contact() is NOT applied. (This is the correct and the expected behavior). Now, on the second 200 OK, again in that part of the config: 1- is_reply() -> OK 2- isbflagset(FLB_NATB) -> OK 3-is_first_hop() -> OK fix_nated_contact() is applied, thus the contact will be changed, and the client will send the ACK with incorrect information leading to another set of issues... >From the docs: https://www.kamailio.org/docs/modules/5.1.x/ modules/siputils.html#siputils.f.is_first_hop *4.30. is_first_hop()* *The function returns true if the proxy is first hop after the original sender. For incoming SIP requests, it means there is only one Via header. For incoming SIP replies, it means that top Record-Route URI is 'myself' and source address is not matching it (to avoid detecting in case of local loops). Note that it does not detect spirals, which can have the condition for replies true also in the case of additional SIP reply receival.* So going back to the examples: first 200 OK: 1- "top Record-Route URI is 'myself' -> FAIL So we we are NOT the first hop, we do nothing and forward the reply to the client. second 200 OK: 1- "top Record-Route URI is 'myself' -> No record-route headers are present, so we enter the is_first_hop() condition and modify the contact with fix_nated_contact(). Now to the real topic, I have a workaround as: ... if (is_reply()) { if (isbflagset(FLB_NATB)) { if (is_first_hop()) { if (!ds_is_from_list()) { # <-- Check to see if the reply is coming from our internal servers fix_nated_contact(); } } } } ... And that is working correctly, but I would like to understand the reasons. I hope I have explained myself correctly, otherwise it's impossible to get to the point of my questions: 1- Is it correct for is_first_hop() to detect the second 200 OK as a first hop when it isn't? the behavior matches the documentation, so I don't know. If we stick to the check of the headers etc etc, it's working as described, if we stick to the concept of kam1 being actually being the first hop of that 200OK, then the check would need another condition to exclude the 200 OK (or better, the replies) of an in-dialog INVITE. 2- Do you guys consider the workaround something reasonable? Under my opinion I would like to not have to add that, but I also don't know. 3- Am I missing something super standard that avoids all of this? I'm starting to go crazy trying and comparing different things to get to understand this and I want to make sure it's not just a is_first_hop() bug? Sorry for such a long email, but I think that describing the scenario and flow was required. Any input is more than welcome! Thanks! Joel.

Question on the new Kamailio v5.x Releases
by Ginhoux, Patrick 27 Jun '18

27 Jun '18

Hi, I always read your email regarding new stable releases. I am currently working on a project upgrade of multiples servers to the most recent OS (Windows, RedHat) and middleware. In this project, I have upgraded SIP Proxies server running on old version of Kamailio, to the 5.0.1 release (over RedHat 7.4). Effort to make that upgrade and tests have been done with success in the last months. So considering to upgrade to the 5.0.7 or 5.1.4 would be a subsequent work I need to evaluate. I could read all the release notes, but it is also a big challenge to determine if fixes are interesting for me. Based on your experience, is there particular cases, fixed in the new release I need to pay attention? Any comments are welcome. Regards Patrick GINHOUX

Hello, I thought of start planning the next IRC devel meeting, it is quite some time since the last one with a busy spring for most of us. Among the topics to be approached would be the roadmap to the next major release, then discuss what else we can do for or with the project. My proposal as a date is Tuesday, June 27, at 14:00 UTC -- I created a page for it: - https://www.kamailio.org/wiki/devel/irc-meetings/2018a List yourself if you can participate or you prefer a different date, as well as add new topics that you consider they should be approached. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference -- www.kamailioworld.com

Kamailio installation
by Danny Roberts 23 Jun '18

Newbie: TOPOH in SBC/Proxy scenario regarding To-header
by Kevin Olbrich 21 Jun '18

21 Jun '18

Hi! I set up a proxy in front of an asterisk server to handle registration and similar. This setup needs topology hiding. I enabled and configured TOPOH which is working well. The only header which leaks network details is "To". It lists the proxys internal IP. Sure, a proxy should not alter the To and I am investigating if this can be changed in asterisk but is it even possible? Kind regards Kevin

Kamailio + FreeSwitch + WebRTC
by Emanuel Gianico 21 Jun '18

21 Jun '18

Hi everybody, I followed this tutorial https://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc#kamail… And it works fantastic! The next step was to add WebRTC support, so I added WebSockets module to enable web clients to register on kamailio. It works flawlessly and webphone clients register OK! (Followed this http://nil.uniza.sk/sip/kamailio/configuring-kamailio-4x-websocket ) Now, when I call from a softphone (eyeBeam) to the web client (jssip) the other party reach okay, rings okay, but when I pickup de call (from the web client), the softphone goes directly to the VoiceMail. >From the logs I see the jssip throw this error: "Failed to set remote offer sdp: Called with SDP without DTLS fingerprint." I would like to avoid RTPEngine, because from what I understand, FreeSwitch can handle the media part. Can somebody please have the kindness to guide me on how to enable webrtc between Kamailio and FreeSwitch? If somebody needs to see the "kamailio.cfg" please let me know, and i would upload the file to a gist. Cheers, Emanuel.

21 Jun '18

Hello, I am considering to release Kamailio v5.0.7, out of git branch 5.0, sometime next week, likely to happen on Thursday, June 21. As usual, if there is any issue not reported yet on github, do it a soon as possible to have a chance to investigate.

Kamailio 5.1.2 and Module PDB: pdb_query returns always 0
by Stefan Rüetschli 20 Jun '18

20 Jun '18

Hi I have here Kamailio 5.1.2 with PDB Module. I use the documented function from PDB-Module as follows: pdb_query("$rU", "$avp(i:82)"); xlog("L_INFO","PDB result $rU: $avp(i:82)\n"); The problem is, that $avp(i:82) is always 0. If I test the PDB-Server, with "pdbt -r localhost:5574 query <phonenumber>" I get a valid response. I use this already with Kamailio 4.3.6 and there it is working. https://kamailio.org/docs/modules/5.1.x/modules/pdb.html Any ideas? Thanks & regards Stefan

20 Jun '18

Dear sir, I'm using Kamailio 4.4.0 and 5.1.4 IMS module. During using SIPp 3000 subscriber register testing, after enabling PCSCF DB URL function, the contents of 3000 subscribers on PCSCF location table are the same. Using the same IP address and UDP port of 3000 SIPp REGISTER message seems to be the problem. Anyone can help me? Thanks a lot.

KEMI routing script Python exceptions with empty traceback
by Michael Loughrey 19 Jun '18

19 Jun '18

Hi All, I'm using app_python with a KEMI Python routing script. I have been getting occasional Python exception error logs : kamailio[2242]: 8(2253) ERROR: app_python [python_support.c:150]: python_handle_exception(): python_exec2: Unhandled exception in the Python code: kamailio[2242]: TypeError: an integer is required The scripts seems to function without an issue but these error logs appear fairly frequently, always with an empty Python stack trace. I am running Kamailio 5.1 on a Debian 9 system and using Python 2.7 : >>:/usr/local/etc/kamailio# python --version Python 2.7.13 >>:/usr/local/etc/kamailio# kamailio -v version: kamailio 5.1.4 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 18:56:43 Jun 8 2018 with gcc 6.3.0 I have also tried using a Kamailio load built from the master branch (commit f8b8cecb) which gives enhanced exception logging identifying the function an exception occurs within and parameters. I see this occurring in different parts of the routing script e.g. from script def ksr_onsend_route(self,msg): KSR.xlog.xdbg("ONSEND_ROUTE fs=[$fs] $mb\n"); return 1; an exception is reported within ksr_onsend_route() even when the log level is info. Changing log to xlog.xinfo, the log is seen to be sent to syslog but again the exception is reported. These exceptions are always "TypeError: an integer is required" but don't seem related to the Python script. Here is an example of the log with a patch applied to to Kamailio 5.1 to show the function the exception is reported within. kamailio[14092]: 6(14103) ERROR: app_python [python_support.c:156]: python_handle_exception(): apy_exec: ksr_reply_route((null)): Unhandled exception in the Python code: kamailio[14092]: TypeError: an integer is required . . . kamailio[14092]: 22(14119) INFO: <script>: ONSEND_ROUTE fs=[udp: 10.0.31.126:5080] ACK sip:10008@media.test.io:5061;transport=TLS SIP/2.0 . . . . kamailio[14092]: 22(14119) ERROR: app_python [python_support.c:156]: python_handle_exception(): apy_exec: ksr_onsend_route((null)): Unhandled exception in the Python code: kamailio[14092]: TypeError: an integer is required Has anyone got an idea what can be causing these exceptions and how to avoid them? Currently I have simply patched the load to drop the level of this log to debug when such an exception occurs with an empty traceback as they seem spurious. Cheers Mike

Installing RTPengine on CentOS 7
by Francisco Valentin Vinagrero 19 Jun '18

19 Jun '18

Hi, I'm trying to install RTPengine in the same machine as I have Kamailio, running CentOS 7, but there are a few dependencies that yum cannot seem to resolve and I that cannot find anywhere else. As soon as I try to build the daemon it produces these errors: make[1]: Leaving directory `/usr/local/src/rtpengine/daemon' Failed build with ../lib/fix_frame_channel_layout-01.h Trying build with ../lib/fix_frame_channel_layout-02.h make[1]: Entering directory `/usr/local/src/rtpengine/daemon' rm -f "resample.c" echo '/******** GENERATED FILE ********/' > "resample.c" cat ../lib/"resample.c" >> "resample.c" Package libevent_pthreads was not found in the pkg-config search path. Perhaps you should add the directory containing `libevent_pthreads.pc' to the PKG_CONFIG_PATH environment variable No package 'libevent_pthreads' found Package libavcodec was not found in the pkg-config search path. Perhaps you should add the directory containing `libavcodec.pc' to the PKG_CONFIG_PATH environment variable No package 'libavcodec' found Package libavformat was not found in the pkg-config search path. Perhaps you should add the directory containing `libavformat.pc' to the PKG_CONFIG_PATH environment variable No package 'libavformat' found Package libavutil was not found in the pkg-config search path. Perhaps you should add the directory containing `libavutil.pc' to the PKG_CONFIG_PATH environment variable No package 'libavutil' found Package libswresample was not found in the pkg-config search path. Perhaps you should add the directory containing `libswresample.pc' to the PKG_CONFIG_PATH environment variable No package 'libswresample' found Package libavfilter was not found in the pkg-config search path. Perhaps you should add the directory containing `libavfilter.pc' to the PKG_CONFIG_PATH environment variable No package 'libavfilter' found So, in the end, at least 'libevent_pthreads','libavcodec', 'libavformat', 'libavutil', 'libswresample' and 'libavfilter' are missing. Trying to install them one by one with yum fails because it cannot find these packages for CentOs 7. Can anyone point me to a solution for this? Thanks, Francisco.

Re: [SR-Users] Textops Regex
by Duarte Rocha 19 Jun '18

19 Jun '18

You're right, it is application/sdp and the back slash works as escape character. However, a new problem came. I'm using this, since someone upstream is adding \r\n to a part of the body : replace_body_all("application\/sdp\r\n\r\n", "application/sdp\r\n"); The regex finds the application/sdp just right, but doesn't replace everything. So, as a final result i get applicationapplication\sdp\r\n. Is this intended? Thanks for your help

Hello, I'm trying to configure Kamailio 5.1 like "presence" server. Pretty much with default settings of kamailio: # ----- presence params ----- modparam("presence", "db_url", DBURL) ;modparam("presence", "server_address", "sip:10.0.6.226:5060" ) modparam("presence", "send_fast_notify", 0) modparam("presence", "db_update_period", 20) modparam("presence", "clean_period", 40) modparam("presence", "subs_db_mode", 2) modparam("presence", "fetch_rows", 1000) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) # ----- presence_dialoginfo params ----- modparam("presence_dialoginfo", "force_single_dialog", 0) # ----- pua params ----- modparam("pua", "db_url", DBURL) modparam("pua", "db_mode", 2) modparam("pua", "update_period", 60) modparam("pua", "dlginfo_increase_version", 0) modparam("pua", "reginfo_increase_version", 0) modparam("pua", "check_remote_contact", 1) modparam("pua", "fetch_rows", 1000) # ----- pua_dialoginfo params ----- modparam("pua_dialoginfo", "include_callid", 1) modparam("pua_dialoginfo", "send_publish_flag", FLT_DLGINFO) modparam("pua_dialoginfo", "caller_confirmed", 0) modparam("pua_dialoginfo", "include_tags", 1) modparam("pua_dialoginfo", "override_lifetime", 124) # ----- dialog params ----- modparam("dialog", "db_url", DBURL) modparam("dialog", "enable_stats", 1) modparam("dialog", "db_mode", 1) modparam("dialog", "dlg_flag", FLT_DLG) And when UDP transport is using, everything works perfect. But when TCP is using (only "listen: tcp:IP:5060" is set) NOTIFY is not send. When "listen: tcp:IP:5060" and "listen: udp:IP:5060" I receive NOTIFY but through UDP.

Timer child process loosing MySQL connections
by Tobias Lindgren 19 Jun '18

19 Jun '18

Hi all! Having an issue with MySQL db connections being dropped in a system running 4.4.7. We're using db_mysql and db_cluster modules setup a cluster connecting two different DB servers. We have two cluster connections, one for acc and one for "other queries". One DB (A) is on the same network, another DB (B) is on another network. The default DB connection is for the remote server B. Auto reconnect is enabled. The specific issue seen is that the "timer" child process looses/drops both connections to DB A and B. Looking at the output from lsof when this happens, the connections usually does not both drop connections for A and B at the same time. Sometimes the connections keep up for ~24h, sometimes for 10 minutes, but normally the problem re-occurs every 6 hours or so. We're seeing this problem on two Kamailio servers, both handling fairly high amount of calls. None of the other Kamailio child processes seems to get their connections dropped, only the "timer" process. To solve this we need to restart Kamailio. Lately I've added the timer.so module to make a simple query on each cluster connection each 10 seconds.

Hi all, Few days back only, I started working on Kamailio IMS. I set up PSCSF, ICSCF, SCSCF and HSS(from open hss). When I try to send Register request from Zoiper, ICSCF is giving request timeout. At SCSCF, MAR failed error is logged. Kindly, let me know where I am doing wrong? >From my observation, At HSS, I can't see MAR request processing, It is only processing UAR from ICSCF.

TLS module and IPv6 (using tls.cfg).
by Joel Serrano 17 Jun '18

17 Jun '18

Hi all, I was playing around with the "config" modparam to specify and use a TLS configuration file instead of inline modparams inside kamailio.cfg. I did some testing and when I went to try with IPv6 I run into a little doubt?? tls.cfg config example: [server:1.2.3.4:5061] <----- How do you put an IPv6 in there? method = TLSv1 verify_certificate = yes require_certificate = no private_key = /usr/local/etc/kamailio/tls/local_key.pem certificate = /usr/local/etc/kamailio/tls/local_cert.pem verify_depth = 3 ca_list = local_ca.pem crl = local_crl.pem Applying the logic of the "listen" param, it should be: [server:[AAAA:BBBB:CCCC:DDDD:EEEE:FFFF:GGGG:HHHH]:5061] But it just seems totally wrong and I haven't found anything in the docs. Any suggestions? Thanks, Joel.

SDPC on SDP
by Duarte Rocha 17 Jun '18

17 Jun '18

Greetings, Please help me understand the reason and source of this behaviour on Kamailio. I receive a 200OK to a RE-INVITE that has : Session Name (s) : MySession Connection Information (c) : IN IP4 xxx.xxx.xxx.xxx Then, Kamailio routes the 200OK to it's destination, and it leaves Kamailio like this : Session Name (s) : MySession sdpc=IN xxx.xxx.xxx.xxx The line Connection Information got deleted and it's info is now on Session Name. How can i disable this ? Thanks

Alias listen
by kai.ohnacker＠cbc.de 17 Jun '18

17 Jun '18

Hello everybody, I have a question about the function "aliases". With my server no alias entry is registered and there is no DNS server (reverse DNS is not possible) in the network. Nevertheless, the SIP server listens to a defined alias. Is there next to the config file and the kamctlrc file another place where an alias can be entered? Cheers, Kai

Hi, I'm making my first steps in Kamailio, and need help for a simple configuration. I am trying to configure Kamailio to forward SIP traffic from (and to) a SIP gateway to a Twilio SIP trunk: SIP gateway ----> Kamailio ----> Twilio SIP trunk How to configure Kamailio for this use case? How the kamailio.cfg file will look like in such case? Thanks.

add_uri_param with variables
by Patrick Wakano 15 Jun '18

15 Jun '18

Hello list, Hope you all doing well! We've been attempting to add a URI parameter to implement the trunk group (tgrp and trunk-context) but discovered the add_uri_param() function only works with constant string.... we can't use a pseudovar to inform the value to be added. Anyone knows why such limitation? Can it be changed? It is possible to do the same thing via the subst_uri function, but it would be so much more elegant to use the function... Thank you, Kind regards, Patrick Wakano

outbound flow tokens and kamailio restart

Hello all. I have created a WebRTC to SIP gateway. I implemented it using the outbound module. If I restart Kamailio during a call, subsequent messages fail to be routed. {1 322 BYE 218565972_26748892(a)x.x.x.x} INFO: outbound [outbound_mod.c:261]: decode_flow_token(): flow-token failed validation {1 322 BYE 218565972_26748892(a)x.x.x.x} INFO: rr [loose.c:519]: process_outbound(): failed to decode flow token {1 322 BYE 218565972_26748892(a)x.x.x.x} INFO: rr [loose.c:794]: after_loose(): failed to process outbound flow-token Is it possible to make the flow token survive a restart?

Re: [SR-Users] Using a var as timeout value in dlg_set_timeout_by_profile function

Hello Jan, I just looked quickly in the code, it seems that the timeout value is not interpreted as "pseudo-variable", therefore its not possible to use something like $var in this method right now. It is just read as a numeric value. dialog.c, line 1342: if(dlg_set_timeout_by_profile((struct dlg_profile_table *) profile, &val_s, atoi(timeout_str)) != 0) This can of course changed in the module with a change in the code.

can't assign values to $fU

14 Jun '18

From the online documentation:$fU - From URI username *$fU* - reference to username in URI of 'From' header It is R/W variable (you can assign values to it directly in configuration file) But i am no able to assign values to $fU. Has anyone experienced this? Snippet of code in the configuration file of mine and its respective logs showing that $fU is not getting overwritten. I have tried to hard code values to it assign variables to it, all to no avail. configuration file code snippet: xlog("L_INFO", "[$ci] from header username pre mod: $fU"); $fU = "5555555555"; xlog("L_INFO", "[$ci] from header username post mod: $fU"); Logfile snippet: INFO: (s) [7EAB8FECD723E8444E36C659F331068B41EC6BB0] from header username pre mod: 3224567880 INFO: (s) [7EAB8FECD723E8444E36C659F331068B41EC6BB0] from header username post mod: 3224567880 Thanks, Karthik

Kamailio as outbound proxy for PBX
by Wilkins, Steve 14 Jun '18

14 Jun '18

Good Morning All! If a PBX(Asterisk) uses an outbound_proxy (such as Kamailio), can Kamailio actually make the SIP call? At some point I would like outbound calls to be controlled by Kamailio so that the outside endpoints never communicate with the PBX. Currently a call goes through Kamailio to Asterisk and then Asterisk communicates with the endpoint, and this is night ideal Thanks ALL

t_save_lumps() and failure_route
by Julien Chavanton 14 Jun '18

14 Jun '18

Hi, I have a scenario where I am using. t_save_lumps(), lookup() and then I can choose to drop some branches in branch routes. However, it is possible that I endup without any branch left, in this case t_relay() is returning and no failure route is called/created. At this point I need to recover the original message I believe it is not possible to restore/reset the message without passing by failure route ? Else, I could trigger a failure route using t_relay(), is there any "handy/clean" way to trigger failure_route() ? Regards

Memory leak in tm with push notifications
by Ivaylo Markov 14 Jun '18

14 Jun '18

Hello, I am trying to set up Kamailio as a push notifications proxy, closely following the example in the "Kamailio in a Mobile World" presentation (https://www.slideshare.net/FedericoCabiddu/kamailioinamobileworld-51617342). I am running Debian 9 and Kamailio 5.1.3 from the official Debian repositories. I believe the main modules involved in the issue below are tm, tmx, and tsilo. Every call passing through the proxy leads to a small memory leak in the tm module - there is a large amount of "delayed free" memory cells from tm's internal hash table. At some point the shared memory runs out and Kamailio restarts. Using the "kamcmd corex.shm_summary" command I was able to see that the top users of shared memory are "tm: h_table.c: build_cell" and "core: core/sip_msg_clone.c: sip_msg_shm_clone" with the same allocation count. I experimented with removing different parts of the configuration and noticed that commenting out the "t_continue(...)" call in the "PUSHJOIN" route (see slide #22) prevents the leak from happening. Maybe something in that function is incrementing the reference counter to the hash table cell, but it is not decrementing the counter when done? I tried looking around the source code of the tm and tmx modules, but saw nothing suspicious. I also tried using gdb with a breakpoint in t_continue_helper (tm/t_suspend.c:166) hoping to see what else is accessing the htable cell, but was unable to find anything of use. Has someone encountered anything like this? Can you provide more directions on debuggin this? I can provide some bits of configuration, but an entire test setup would be rather difficult, unfortunately. Thank you for your time, Ivo

Using a var as timeout value in dlg_set_timeout_by_profile function
by jenus＠cyberchaos.nl 13 Jun '18

13 Jun '18

I'm trying to use the dlg_set_timeout_by_profile in the xhhtp route to update the dialog timeout for active calls. But if i use a var as the timeout value the call disconnects immediately. This works fine (call disconnects after 80 sec): dlg_set_timeout_by_profile("subscriber_outbound", "$var(SipName)@$var(SipDomain)::$var(DialogCallid)", "80"); This fails (call disconnects immediately: $var(DialogTimeout)= 80; dlg_set_timeout_by_profile("subscriber_outbound", "$var(SipName)@$var(SipDomain)::$var(DialogCallid)", "$var(DialogTimeout)"); Are vars supported in the dlg_set_timeout_by_profile function? And is it possible to use it in any route as described in the docs? I'm running kamailio 5.1.3. Thanks, Jan

Registration of UACs i n a partially encrypted scenario

Hello, we are pretty new to SIP and kamailio, we do have some questions regarding the following scenario: We have a number of UACs in a small network which are required to communicate without encryption because the are not able to consume certificates. We want to use kamailio (as a proxy?) to establish an encrypted connection to a backend UAS. 1. Is it possible to directly register the UACs with the UAS eventhough communication between kamailio and the UAS is encrypted ? 2. How do we need to configure kamailio in order to make this scenario work ? Thank you for your suppport

Asterisk inviting Kamailio
by Wilkins, Steve 13 Jun '18

13 Jun '18

Hello All, I have noticed that sometimes when a call is made from one endpoint to another through Asterisk via Kamailio, Asterisk sends an INVITE to Kamailio even after the call has been established. Sometimes this does not happen. When it does happen, calls drop. Why would an INVITE be sent back to Kamailio? Also, Pan, I am working on the response you requested yesterday. Thanks you All, -Steve

It must definitely be some sort of Codec issue though, since I can seem to move the problem around and actually finally get video on the softphone. It was a little strange that I lost Audio on the WebRTC client though, since I only disabled VP8. Since Kamailio is only relaying I am so confused why introducing Kamailio is messing up Video.

Disable basic authentication?
by Skip Morse 11 Jun '18

11 Jun '18

Hi All, I couldn't get a clear answer from the documentation. Based on the description of www_authenticate and proxy_authenticate: " The function verifies credentials according to RFC2617. If the credentials are verified successfully then the function will succeed and mark the credentials as authorized (marked credentials can be later used by some other functions). If the function was unable to verify the credentials for some reason then it will fail and the script should call www_challenge which will challenge the user again." The RFC outlines basic and digest auth. Is there a way to disable the ability for a UA to use basic auth? Or maybe these is disabled already? I'm likely understanding this wrong, it seems to me that it's allowed for a UA to auth with basic even if the challenge is for digest. Any clarification would be helpful. Thanks! -Skip

sip digest authentication
by eyas barhouk 11 Jun '18

11 Jun '18

Hello dears I’m trying to setup Kamailio with sip digest authentication scheme by using the following configuration from s-cscf side : modparam("ims_auth", "registration_default_algorithm", "HSS-Selected") and the result was as following : 1. when the register message passed form the s-cscf to the hss and in the diameter trace I found the “SIP-AUTHENTICATION-SCHEME” in the MAR request as “Digest-MD5” 1. After that the HSS send MAA message with “DIAMETER-ERROR-AUTH-SCHEME-NOT-SUPPORTED” 2. S-cscf replay with the message “Forbidden – privet identity not found (Authorization : username)” So based on that could any one tell where was my mistake or how can I setup Kamailio with SIP-DIGEST scheme Thanks

JSON RPC Error: LUMP_RPL_BODY already added!
by Asgaroth 11 Jun '18

11 Jun '18

Hi All, We are trying to query the json rpc server on our registrar for the contact of an aor, but we are seeing the following error(s) being displayed in the log when we query the location table: ERROR: <core> [core/data_lump_rpl.c:83]: add_lump_rpl2(): LUMP_RPL_BODY already added! ERROR: xhttp [xhttp_mod.c:410]: xhttp_send_reply(): Error while adding reply lump We are getting the aor details back in response from the rpc call, but the error's in the log are a little concerning and I cannot see where we are doing something wrong. As an example, the following curl request returns the correct response, but the above error is displayed in the log, Am I doing something wrong here, I cannot see what the issue is: curl --header 'Content-Type: application/json' --data-binary '{ "jsonrpc": "2.0", "method": "ul.lookup", "params": [ "location", "user(a)example.com" ], "id": 3 }' http://registrar.example.com/rpc A secondary question is, is there an upper limit on the size of the "id" parameter? This kamailio instance is v5.0.6. Any thoughts as to what this error means? Thanks

(N)DB_FIREBASE module?
by Pan Christensen 11 Jun '18

11 Jun '18

Greetings all. We are currently developing web and mobile apps using firebase: https://firebase.google.com/products/realtime-database/ . We have been discussing the possibility of Kamailio querying this database. I assume that it will be possible to query it using HTTP and JSON modules, but it would probably be easier to use the DB API. Any plans to develop such a module? With kind regards Pan B.
