Releasing Kamailio v5.5.1
by Daniel-Constantin Mierla 15 Jun '21

15 Jun '21

Hello, I am considering to release Kamailio v5.5.1 sometime next week, likely on Tuesday or Wednesday (June 15 or 16, 2021). This is the usual heads up notification to see if anyone is aware of issues not yet reported to bug tracker and if yes, do it as soon as possible to give them a chance to be fixed. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

Is Kamailio GPL or GPLv2
by Yan Gao 15 Jun '21

15 Jun '21

Hello, I have a question about the license of Kamailio. It is said to be GPL in https://www.kamailio.org/w/: "Kamailio® (successor of former OpenSER and SER) is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second...." But GPLv2 in https://www.kamailio.org/w/info/ : "Kamailio is released under GNU Public License v2 (GPLv2). Beginning with 3.0.0, the application includes parts of code under BSD license that can be used such as individual components." Which one is the correct description? Thanks & Regards, Yan

vsf/vst question
by David Escartín 15 Jun '21

15 Jun '21

Hello all! as we knew vsf/vst were added to the RR header when using uac_replace for From/To headers. BUt we observed that some versions ago (we are using now 5.4) that stop happening with this setup modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) modparam("rr", "enable_full_lr", 0) modparam("rr", "enable_double_rr", 1) modparam("rr", "append_fromtag", 1) and only ftag, did are added as param to RR However we have seen that when using multihomed kamailio instance and doing uac_replace, vsf/vst are included also with ftag and did params. Is that behaviour known or expected? thanks a lot and regards david -- <http://www.sonoc.io/> David Escartín NOC engineer *www.sonoc.io* <http://www.sonoc.io/> [image: LinkedIn] <https://www.linkedin.com/company/sonoc> [image: Twitter] <https://twitter.com/sonoc_> [image: Facebook] <https://www.facebook.com/SONOCio/> This e-mail is for the exclusive use of its recipients and may contain business secrets or other confidential or privileged information.

using path in Subscriber table
by Thành Trần Duy 14 Jun '21

14 Jun '21

Hi all, First of all, I would like to present the system model we are applying: - dSIPRouter : Sip relay for all users connected from the internet (installed with RTPEngine to handle media data). - kamailio 5.3.5: core system, registration server. - Asterisk 17: SBC. Sorry if our model seems a bit backwards but we have so many users (>12k configured users, > 3k concurrent registered users, > 500 concurrent users at cps 10), I don't know of any solution that can work with such a large load. With call outbound (from user to PSTN via SBC), everything is fine. But with internal or inbound calls, it wasn't successful. I showed that: - After dSIPRouter, the register message has Path parameter in SIP Header, - Kamailio store sip:user@domain in column contact at location table. - Using modparam registrar with use_path=1, path_mode=0, path_use_received=1, I stored this parameter in DB. - When calling internal or inbound, for the search destination of a phone, I am using sip_trace() function. But the result is always column contact. - With this uri, kamailio wasn't known and sent the invite to proxy. - Final error message: 404. I need one of these solutions: - get path column when result of sip_trace() like sip:user@domain (with phone in internal network, it like sip:user@ipaddress). - write path value to column contact when the register message has it. - sip_trace can get a path instead of contact if it has. Or you can have other solutions, pls help me. We can talk and test via my Webex PMR. Many thanks, Thanh Duy Tran

Dear all, I setup a Kamailio 5.5.0 (from GIT) on a ubuntu Ubuntu 18.04.5 LTS and I have some error with the libssl/ libmysql, seems not happening every time. Regarding the config file, it's a config running correctly on a Kamailio 5.3.x on a centos 7 I have attached the returned error and the result of the core file. Any idea ?

Kamailio SBC+ Freeswitch as media server
by John Tuxies 09 Jun '21

09 Jun '21

in a Debian system i am running Kamailio 5.5 installed from repo and with the basic setup i have 2 users 101 & 102 to be able to call each other. So far so good. i added Freeswitch in the same system and tried to follow this guide http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc even though it is old and there are many changes. Freeswitch is installed from deb repo as well. after following the guide i tried to adapt to newer versions of kamailio and freeswitch, but i am getting errors. The problem is that the users now are able to register to Kamailio, but unable to call each other. I can see users being registered in Kamailio: *root@kamfs: ~ $ kamctl online101102root@kamfs: ~ $* while when 101 calls 102 i am getting: *2021-06-08 10:35:19.015670 [NOTICE] switch_channel.c:1118 New Channel sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> [f3b8f5a0-652a-4640-b2d3-9b7cc21d7f91]2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:585 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Running State Change CS_NEW (Cur 1 Tot 5)2021-06-08 10:35:19.015670 [INFO] sofia.c:10362 sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> receiving invite from 192.168.1.15:5060 <http://192.168.1.15:5060> version: 1.10.6 -release-18-1ff9d0a60e 64bit call-id: ZDFiZWFkZmVmYjgxZDEwOTgyYTYxZjkxNzkwMzlmYmQ.2021-06-08 10:35:19.015670 [DEBUG] sofia.c:10456 verifying acl "domains" for ip/port 192.168.1.15:0 <http://192.168.1.15:0>.2021-06-08 10:35:19.015670 [WARNING] sofia.c:10569 IP 192.168.1.15 Rejected by acl "domains"2021-06-08 10:35:19.015670 [NOTICE] sofia.c:2445 Hangup sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> [CS_NEW] [CALL_REJECTED]2021-06-08 10:35:19.015670 [DEBUG] sofia.c:1549 Channel is already hungup.2021-06-08 10:35:19.015670 [DEBUG] sofia.c:1549 Channel is already hungup.2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:604 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State NEW2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:585 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Running State Change CS_HANGUP (Cur 1 Tot 5)2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:848 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Callstate Change DOWN -> HANGUP2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:850 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State HANGUP2021-06-08 10:35:19.015670 [DEBUG] mod_sofia.c:453 Channel sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> hanging up, cause: CALL_REJECTED2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:60 sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> Standard HANGUP, cause: CALL_REJECTED2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:850 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State HANGUP going to sleep2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:620 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State Change CS_HANGUP -> CS_REPORTING2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:585 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Running State Change CS_REPORTING (Cur 1 Tot 5)2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:936 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State REPORTING2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:174 sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> Standard REPORTING, cause: CALL_REJECTED2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:936 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State REPORTING going to sleep2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:611 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State Change CS_REPORTING -> CS_DESTROY2021-06-08 10:35:19.015670 [DEBUG] switch_core_session.c:1736 Session 5 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Locked, Waiting on external entities2021-06-08 10:35:19.015670 [NOTICE] switch_core_session.c:1754 Session 5 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Ended2021-06-08 10:35:19.015670 [NOTICE] switch_core_session.c:1758 Close Channel sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> [CS_DESTROY]2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:739 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) Running State Change CS_DESTROY (Cur 0 Tot 5)2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:749 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State DESTROY2021-06-08 10:35:19.015670 [DEBUG] mod_sofia.c:364 sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> SOFIA DESTROY2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:181 sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15> Standard DESTROY2021-06-08 10:35:19.015670 [DEBUG] switch_core_state_machine.c:749 (sofia/internal/101(a)192.168.1.15 <101(a)192.168.1.15>) State DESTROY going to sleepfreeswitch@kamfs>* i am attaching the kamailio.cfg file and the whole /etc/freeswitch folder, if someone could help me to solve this issue, please.

Any way to force socket used to reach databases ?
by David VILLAUME 08 Jun '21

08 Jun '21

Hello, I’m trying to initiate a redis connection in ndb_redis for topos_redis on a keepalived slave host, but host tries to use the VIP instead of the second socket I defined. Is there a way to influence the ‘database source socket’ so the server can connect with a secondary address even if it does not own the keepalived VIP (tried mhomed options without improvment) ? Regards, David
