Re: [SR-Users] Kamailio Processes Stop Responding
by Peter DiSanto 05 Dec '16

05 Dec '16

OK thank you Alex. I will look into your suggestions next time the problem arises. Each call does generate one SQL LCR lookup, one CDR INSERT, and also a timer route that runs 3 queries every few minutes. Once Kamailio stops responding it will continue that way indefinitely until a process restart. Will report back. Thanks. Pete D

Restructuring source code tree for v5.0
by Daniel-Constantin Mierla 05 Dec '16

05 Dec '16

Hello, I already started playing with various scripts to do the restructuring of the source code tree for v5.0 as we discussed in the past months and I am considering to do it quite soon, in the next few days. The result will look like: /Makefile (only-forwarding make commands to various subdirs) /README|INSTAL|LICENSE|... /src/Makefile* (build makefiles) /src/main.c (main c file to generate the binary) /src/core/*.{c,h} (c code for core, including subfolders such as parser, mem, atomic, ...) /src/lib/* (subfolders with the internal libraries) /src/modules/* (subfolders with the modules) Other subfolders from root directory may be relocated, but to be decided along the way. At the time of doing the restructuring, I will try to merge all the pull requests that look ok. Therefore it would be good that anyone interested in open pull requests to do the review (and merge) meanwhile. Also, I think it would be good to disable travis and nightly master builds during few days when the restructuring happens in order to avoid flooding sr-dev with alerts. If anyone has suggestions to add, do not hesitate to write on mailing lists.

Rtpproxy settings without NAT in Kamailio
by shantanu saha 03 Dec '16

03 Dec '16

Hello, I am trying to configure rtpproxy with Kamailio. kamailio.cfg is already configured (default) for rtpproxy. I just add the following line at the top of the cfg file. *#!define WITH_NAT* After that rtpproxy is working in local network. Both client and sip server are running in local network. But when I run this in public network, rtpproxy didn't trigger. Rtppoxy and Kamailio are running in same public IP, Sip client also running in another *public IP. *So there is *no NAT* *.* Both local and public version was Centos 6 Kamailio version : 4.4 rtpproxy version: 2.1 Note: udp connection between rtpproxy and Kamailio was established (both in public and private network) Thanks shantanu saha

Dual Stack Environments
by Colin Morelli 02 Dec '16

02 Dec '16

Hey all, Sorry for two questions out at the same time! I'm using kamailio in front of FS, and I'm about to enable IPv6, but I have a question that I'm not entirely clear on. What's the proper way to forward traffic using the same interface that it came in on? Specifically, if a client connects to kamailio on IPv6, it should connect to FS on IPv6, so that FS knows to advertise its v6 address in the SDP. The same should be true for v4. Is this possible? Best, Colin

Local messages are malformed in Kamailio 4.4.X

Local messages are malformed in Kamailio 4.4.X. For example after receiving an error response (603) to an INVITE message, the ACK is generated with header Max-Forwards concatenated to header CSeq and double CRLF, which is wrong. Via: SIP/2.0/TLS 173.16.10.61:5061 ;branch=z9hG4bKc782.5b960c7c48a4363a0126963daa797eb0.0;i=7 From: "22861"<sip:22861@173.16.10.61;transport=tls>;tag=snl_OIPEOzJUNy Call-ID: 61b500a71b510a1Pj61qq1k9dPW To: <sip:551138174108@174.16.4.108:5061;transport=tls>;tag=435012226 CSeq: 2351 ACKMax-Forwards: 70 User-Agent:...

help with string modification

Hello All. I have some troubles with upstream sip switch. It ignores SIP packets which contains: User-Agent: FPBX-2.11.0(11.17.1) or Server: User-Agent: FPBX-2.11.0(11.17.1) If space is present before first "(" then sip switch works as expected So my question is: how corektly make analyze and modify this headers using kamailio? In which routes i must parse it? i need such modifications: User-Agent: FPBX-2.11.0(11.17.1) -> User-Agent: FPBX-2.11.0 (11.17.1) Server: User-Agent: FPBX-2.11.0(11.17.1) -> Server: User-Agent: FPBX-2.11.0 (11.17.1) Thank you. -- Best regards, Sergey Basov e-mail: sergey.v.basov(a)gmail.com

Please see my reply on a thread on this topic: http://lists.sip-router.org/pipermail/sr-users/2016-February/091612.html Q2: given that TSILO depends on the users' location you have to put it in the Registrar.
