by Timo Klecker 10 Dec '14

10 Dec '14

Hi all! Our Kamailio (3.1.4) crashed when modifying the username-Part of a Request URI using: $rU = $(rU{s.strip,6}); Initial Request URI: /sbin/kamailio[40658]: NOTICE: <script>: [ INVITE ] Got new Packet to sip:123456:pass@sip.custom.com The config-script now removed the first 6 chars from the username part and would replace them in one of the following lines, but Kamailio had problems here: /sbin/kamailio[40658]: ERROR: pv [pv_core.c:251]: failed to parse the R-URI /sbin/kamailio[… [View More]

Hi All In 4.2.0 Kamailio (S-CSCF), when I try to register an IMS endpoint, I get 403 from P-CSCSF.

Kamailio Crash
by Kristian Kielhofner 09 Dec '14

09 Dec '14

version: kamailio 4.1.6 (x86_64/linux) 58746c I looked through 4.1 commits but didn't catch anything that looked like a fix for this but it's a very real possibility this is a duplicate (again). Any thoughts (backtrace attached)? Thanks! -- Kristian Kielhofner

Kamailio TCP Proxy
by Andrew Mason 04 Dec '14

04 Dec '14

Hi All, I am testing SIP messages through the proxy from one client to another and the sender specifies TCP as the transport but Kamailio seems to overwrite this and chooses UDP (TCP is specified in the contact header). The receivers are manually registered using kamctl ul add so i am not sure if this is forcing UDP or something else - I have redirected the messages to wireshark and attached an example of Kamailio adding its VIA headers but specifying UDP (taken from destination). Basically … [View More]

Some Questions about Kamailio UDP Transport and Concurrency
by pengxuejin＠gangbeng.com 04 Dec '14

04 Dec '14

Dear Kamailio Developers： Hi. I have some questions about kamailio, and want to gain some suggestions from you. 1、The 4 UDP child processes are using system resources(CPU、memory), but they are using only one CPU core(I use 8 core CPU). Why? 2、The ablity of handling the Concurrency is alike, no matter how many UDP child processes I use. Why? And what's the effection of the other UDP child processes? 彭学金 186-2708-0286 技术部开发工程师武汉九午科技有限公司武汉市洪山区光谷大道国际企业中心锦丰楼A座405室 Tel:(027)87108832

Issue with 4.2.0 and nathelper and/or rtpproxy
by Igor Potjevlesch 04 Dec '14

04 Dec '14

Hello, Since I done the upgrade of Kamailio into 4.2.0, there are, at least, one new case where the RTPProxy is launched. When I got an INVITE from my PSTN Gateway, for unknown reason (and not for all calls), Record-Route is append with nat=yes. I looked into an old trace and this behaviour didn't exist. What could have changed that can explain this? Regards, Igor.

One way audio calls
by Will Ferrer 03 Dec '14

03 Dec '14

Hi All We are experiencing an odd problem with 1 way audio in about %6-%8 of our calls. It seems to me that what is happening is that our kamailio installation (using rtpengine) is some times ignoring the c= attribute that the carrier is sending us, and sending our audio instead to either address in the carriers o= attribute, or just to the same address we sent our sip invite too. We have looked at hundreds of calls and haven't found a reliable pattern why this happens some times and not … [View More]
