[Kamailio-Users] Newb doco request
by carl Lougher 05 Mar '09

05 Mar '09

Hi, I'm after some useful doco to allow me to setup trunks from Trixbox to Kamailio and push all calls to a sip provider. Would possibly need rtpproxy or nathelper as well. Can anyone point me in the right direction as i've been combing the web for days and unable to find anything with good explanations and basic enough for a Kamailio beginner. Thanks, Taff.

[Kamailio-Users] Redundancy and fault-tolerance
by Uriel Rozenbaum 04 Mar '09

04 Mar '09

Hi gentlemen, I'm trying to find a suitable topology to deploy on our SIP network. We started testing UCARP, but it seems it's not going to do for us. Our topology involves 2 servers with physical IPs on them and 2 floating IPs (to balance load 50% on each). The balancing is manual, we are going to point half our servers (measured in load) to one floating IP and so on. When a server fails, the other will handle the load assuming the other floating IP. We found an issue managing IPs, if we … [View More]

[Kamailio-Users] How to send a to-tag in a CANCEL request generated by carrierroute?
by mayamatakeshi 04 Mar '09

04 Mar '09

Hello, I'm using the module carrierroute. I'm setting the carrierfailureroute table to try a second route if the first one times out. The first route is a GW that sends 183 Ringing with SDP and to-tag. But when the failure_route is called due to timeout and the second route is resolved I see kamailio sending a CANCEL without a to-tag and the GW replies with "481 Call Leg/Transaction Does No Exist". So, This fails to cancel the first request. How can I make kamailio send the to-tag in the CANCEL … [View More]

[Kamailio-Users] htable question
by Klaus Darilion 04 Mar '09

04 Mar '09

Hi! Sorry for not knowing how hash table works, thus my questions may be a bit stupid: How many items can be stored in hashtable? Is it limited to "size" parameter, e.g. 10 means max. 1024 entries? Or is it as much as memory is available (what for is the size parameter in this case)? How can I delete a key from htable? Example: I want to track concurrent calls (lets pretend there is no dialog module :-): # pseudo language if INVITE $sht(a=>$ci) = $ts; ... elseif BYE $avp(s:… [View More]

Re: [Serusers] Need easiest way to set/clear a flag and refer to it later in same call session
by Miklos Tirpak 04 Mar '09

Please read the getting started documentation from http://www.iptel.org/doc. This is a bit old, and I strongly suggest to use ser 2.x instead of 0.9.x, therefore some additional documents might be also useful: http://www.iptel.org/ser/doc/010whatsnew. Regards, Miklos p.s. Please post all the questions/answers to the serusers list, others might be interested as well.

[Kamailio-Users] Carrierrout issue
by Ali Jawad 03 Mar '09

03 Mar '09

Hi I do use carrieroute to balance calls to 3 servers and those 3 servers do use a2billing and they forward calls to my pstn gw. I do have a graph that has the active calls on them randomly and it does not depend on the load at hand the calls spike up on all 3 servers together. And most of those calls are in ringing state but with no callerID. Normally in the log for carrieroute I have something like this: Mar 3 13:39:10 [4288] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxxx was … [View More]
