Relaying failure codes back to initial server
by Alexandru Covalschi 15 Dec '15

15 Dec '15

Hello everyone! I need to relay 486/408/... other failure codes back to initial INVITE server. Here http://lists.sip-router.org/pipermail/sr-users/2010-November/066382.html is recommended just to exit failure_route, but that didn't work for me. I need that to let Freeswitch know which cause has ended the call. Now Kamailio just sends ACK to endpoint on receiving 486 BUSY. Would you kindly tell me how to achieve that? Thanks in advance -- Alexandru Covalschi ABRISS-Solutions VoIP engineer and system administrator phone: +37367398493 web: http://abs-telecom.com/

Dispatcher according to called subscriber
by Michael Nielsen 15 Dec '15

15 Dec '15

Hello everyone, I know kamailio can be configured into almsot everything for SIP - and that the dispatcher function is already build for dispatching between multiple sbc's etc... Is it possible to use the dispatcher for routing between multiple sbc's accroding to called subscriber? So I can make it somewhat multi-tentant. So subscriber A always is routed to 1 or more specific sbc's and subscriber B to 1 or more other spcific sbc's?

403 Not Relaying when default port changed
by Javohir Maxmarajabov 14 Dec '15

14 Dec '15

Hello fellow developers... We have been testing Kamailio for a week and it is working great... But some of the our friends reported that they can't connect to our server using their mobile Internet... and it seems default SIP port is blocked by Service Provider... So we decided to change ports... I opened kamailio.cfg and added these lines: listen=tcp:_PUBLIC_IP_:32850 listen=udp:_PUBLIC_IP_:32850 listen=tls:_PUBLIC_IP_:32851 listen=tcp:127.0.0.1:32850 listen=udp:127.0.0.1:32850 listen=tls:127.0.0.1:32851 listen=tcp:10.19.0.5:32850 listen=udp:10.19.0.5:32850 listen=tls:10.19.0.5:32851 port=32850 port=32851 Now clients throwing an error "403 Not relaying"... I tried to enable debugging to see cfgtrace... no errors detected But when I comment out lines above, (with default cfg) everything works fine Where and What am I doing wrong?

IMS-P-CSCF: stripped down version of kamailio.cfg
by Franz Edler 12 Dec '15

12 Dec '15

Dear IMS-experts, I am trying to reduce the complexity of the IMS implementation by disabling the functions which are not required for a pure stripped down IMS core platform. Therefore I deactivate NAT handling, RTP proxy, SBC, dispatcher etc... in a first step. Later on I will add the functions step-by step. According to the requirements. Now I discovered an inconsistency in the configuration file (kamilio.cfg) of P-CSCF. In main routing logic there is the point where P-CSCF distinguishes an originating-initial request from a terminating-initial request. This is done by the code: if (!ds_is_from_list()) { # Originating from Subscriber: route(Orig_Initial); } else { # Terminating to Subscriber: route(Term_Initial); } Unfortunately the function ds_is_from_list() is part of the dispatcher module which I want to avoid in a first step. Therefore another criterion must be used to distinguish between originating- and terminating-initial request. I therefore propose to use the pseudo-user-name "term" in the Route-URI as a distinguisher. What do you think? I am actually thinking about the correct statement (regular expression) to do that. Maybe anyone can help. BR Franz

transformations {s.rm,match}
by Jonathan Hunter 11 Dec '15

11 Dec '15

Hi Guys, I have been using {s.rm,match} to remove occurrences of numbers, however I am aware it removes all occurrences. Is it possible to make it only remove the first occurrence and not all? For example If I am looking to modify 639157407639 I want to remove only the first 63, not both. So I end up with 9157407639 and not 91574079. Is it possible with a transformation of is regex the way ? thanks Jon

Dispatcher Module & ds_load_list enhancement
by jay binks 11 Dec '15

11 Dec '15

Just an observation and enhancement suggestion. VERY occasionally Ive been getting *ERROR: <core> [parser/parse_param.c:591]: parse_params2(): parse_params(): No memory left* Now I know this is the root of the problem BUT ... it would be nice if it didnt leave my kamailio with no dispatchers at all. Im just suggesting that rather than calling destroy_list before re-populating the list. Could this be changed to create a new list, swap over the pointers to the new distributor list ( IF it has > 0 entries ) and then destroy_list . its just a thought ? -- Sincerely Jay
