dlg_set_timeout bye to websockets client
by Switch168 09 Feb '17

09 Feb '17

Hello, Just wondering if it's possible to intercept the bye message that dlg_set_timeout sends out to do some nat_helper function to fix it so the bye can be sent to random.invalid uris. I know there is the edge proxy outbound module but wondering if I can do it without. Regular bye between 2 clients i was able intercept and fix with nat helper but I dont know how to fix the byes that is sent out from dlg_set_timeout function. Thanks in advance! Andrew

Change Priority of Dispatcher
by Rodrigo Moreira 08 Feb '17

08 Feb '17

Hello, Help me with a question. Is it possible to change the prohirity of a Kamailio Dispatcher target at run time, without changing the destination entry in the database? If so, which module should I use? Have you some link for support? Thank you very much. -- Rodrigo M. (37) 9132-4539 (34) 9889-3069 rodrigo.moreira2007

Cannot hear voice with symmetric NAT and STUN
by Khoa Pham 08 Feb '17

08 Feb '17

Hi, I have Kamailio as SIP server and RTP server. Client is PJSIP. I read that STUN is for non-symmetric NAT, and RTP server is for symmetric NAT. Supposed A calls B. If A, B both use symmetric NAT and STUN, they cannot hear each other If A or B use non-symmetric NAT and NOT using STUN, they cannot hear each other. Why is that? I read http://tools.ietf.org/id/draft-takeda-symmetric-nat-traversal-00.txt for Prediction Failure, is that related to this problem ? -- Khoa Pham HCMC University of Science Faculty of Information Technology

Diversion Header - relay messed up
by Roman Dissauer 08 Feb '17

08 Feb '17

When I get an INVITE with Diversion Header the Request is forwarded without Diversion Header and the Request User is taken from Diversion User. Problem is that on the Destination Host I cannot get original Request User what is the intended destination! Is this intended behaviour? How can I change this behaviour? I already tried to delete the Diversion Header on request_route but this didn’t change the behaviour. Thanks in andvance for your help!

Kamailio + Asterisk with multidomain
by Tomas Zanet 07 Feb '17

07 Feb '17

Hello, thanks to this guide http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb I successfully installed Asterisk 11.6 and Kamailio 4.4.4 on the same machine. Everything works fine. Right now I would like to extend this scenario adding MULTIDOMAIN support, which is not enabled by default Do you see any problems / technical limitations to add multidomain support in this scenario? Before enhancing Kamailio cfg file and Asterisk configuration I would like to know: is this possible? As far as I know Kamailio works fine with multidomain support but I don’t know if Asterisk or both processes can support it. Thanks in advance Regards, T. Tomas Zanet Software Design Department tzanet(a)came.com CAME S.p.A.

DMQ Cluster - hosts loose network connectivity
by José Seabra 07 Feb '17

07 Feb '17

Hello there, My DMQ cluster has 4 nodes and by some reason 2 of them lost the network connectivity for long time(~ 4 hours), after the network of these 2 nodes come back they didn't get connected on DMQ cluster automatically, i had to restart kamailio to get them again on DMQ list. My doubts here are: - Is this an expected behavior of DMQ module? - Is there any way of put them again on DMQ bus without need restart kamailio? Thank you Best Regards José Seabra
