Serial forking & q value
by Marino Mileti 10 Oct '14

10 Oct '14

Hi guys, I've tried with success to implement serial forking based on q value (i've followed documentation) with the istruction: append_branch("sip:b@example.com", "0.5"); Now my questions are: is it possible to import URI from db? is it possible to import q value from db too? I would like to change the q value based, for example, on "night & day"; so it would be nice if I can store it on DB and then load it dinamically when i need.For the first question I think that it's possible with … [View More]

Best way to handle 100 but no 180/183?
by Tobias 09 Oct '14

09 Oct '14

Dear Kamailio users, I have an issue with some upstream carriers quickly replying with 100 Trying but then basically times out. I'm looking for a good solution to distinguish between the 100 reply and any other replies, and alter the timeout values. My goal is to be able to re-route calls where the 180/183 is not received within a few seconds, and if the 180/183 is received I'd like to give the call a much longer timeout. I realize there is a "fr_inv_timer" that would do this, but I would not … [View More]

Setting Kamailio User-Agent dynamically
by Errol Samuels 09 Oct '14

09 Oct '14

Hello All, I am using Kamailio in front of Freeswitch and Kamailio is handling the registrations then forwarding to Freeswitch and everything is working for the most part. However, there is niggling pain in the neck issue where the user's User-Agent shows in Freeswitch as kamailio (4.0.6 (x86_64/linux)) instead of the user's Real User-Agent I am trying to get Kamailio to pass the real User-Agent of the user without success. I am able to set a static User-Agent by doing this in the global … [View More]

duplicate information in siptrace table
by Fred 09 Oct '14

09 Oct '14

Hello, I use Kamailio 4.1.3 with siptrace module. In the sip_trace table I see duplicate information, one line with empty and one line with filled traced_user column. The empty lines are useless for me, I would like only entries with traced_user information. Here the siptrace part of kamailio.cfg: #### Parameters for Siptrace module modparam("siptrace", "db_url", DBURL) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_sl_acks", 0) … [View More]

Re: [SR-Users] Segfault in 4.1.6
by David Wilson 09 Oct '14

09 Oct '14

Hi Daniel, Thanks for the response. Reviewing the logs again, the first occurrence was on 25Sep, after upgrading to 4.1.6+precise on 24Sep. Previous upgrades were to: 4.1.5+precise 18Aug 4.1.4+precise June Traffic patterns are fairly uniform over that period. I've installed the nightly (4.1.6+0~20141004025841.74+precise) and we'll see how that goes until the next release.
