[kamailio/kamailio] Wishlist #234: URI transformation to pick up URI scheme (#592)
by Olle E. Johansson 16 Aug '17

16 Aug '17

I would like the URI transformations to be more generic so one can pick up the URI scheme, like HTTP: or TEL: Just an idea --- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/592

[kamailio/kamailio] Do not start Kamailio if no listener address is configured (#1098)
by Sarbyn 15 Aug '17

15 Aug '17

### Description During some test on my server I forgot to configure a valid listen network address. It's my fault but Kamailio crashed with a useless message: > kamailio[4739]: segfault at 0 ip 00007f022ede5e71 sp 00007fff94033f08 error 4 in libc-2.17.so[7f022ec82000+1b6000 I think it's better to abort the startup if no listen address is specified and with an explicit error message, instead of produce a segfault and a crash without any error -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos: fix PRACK message handling (#1097)
by sergey-vb 14 Aug '17

14 Aug '17

Currently PRACK was not handling properly because topos_d.b_contact field are filling only after receiving 200 OK. But PRACK is sending to 183 Progress responce. So I sink that we must filled topos_d.b_contact field after receiving 183 Progress.

[kamailio/kamailio] Kamailio 5.0.2 suddenly stops processing traffic, then generates a core when restarting. (#1172)
by Joel Serrano 10 Aug '17

10 Aug '17

### Description Kamailio suddenly stops working (this is a production server so debug logging is disabled), when we restart it a core is generated and a segfault is logged. ### Troubleshooting The only thing I have seen is some reference to IPv6 in the backtrace. But no idea where to start looking. I'm pretty sure we will need more information, but I don't know how to read or understand backtraces, please let me know what you see in it so I can dig deeper into this problem. #### Reproduction I don't know how to reproduce yet, first I have to understand the cause. #### Debugging Data Backtrace: ``` [New LWP 12052] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

[kamailio] PID file permissions (#231)
by Arsen 26 Jul '17

26 Jul '17

ENV: Debian 8 So on most Linux systems the /var/run folder is a tmpfs and after which clears after each reboot As I try to start up kamailio after a reboot through kamctl I get the following error. "ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed" Because kamailio does not have the permission to write to the /var/run folder as the kamailio user. Would it be possible to add in the "kamctl" code a section where the SPECIFIED PID LOCATION (/var/run/kamailio) is checked and if it does not exist create it as the root user and chown it to the SPECIFIED USER (kamailio)? The way I have patched it for now is to create a init script that creates a /var/run/kamailio folder and chmods it to kamailio:kamailio Thanks everyone! --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/231

Developing charging module for kamailio-ims
by Prasannakumar Merugu 05 Jul '17

05 Jul '17

Hi all, We are developing charging module for kamailio-ims. We need events event_route[dialog:start] event_route[dialog:end] for detecting call begin and call end. We have to use ims_dialog module for IMS implementation. But observed that ims_dialog module doesnt have the above said events [dialog:start and end]. How do we implement those events using ims_dialog. Is there any other way out. Kindly suggest. Thanks, Prasannakumar Merugu.
