Re: [SR-Users] ASN.1 HI2- IRI-Parameters
by Mojtaba 06 Jun '18

06 Jun '18

Any idea in this regards? I understood it's structure of HI2Operations as ASN.1 IRI-HI2, I attached it. I think i should convert SIP signalling flow to this structure for transmission. Is it right way that i am doing?

Kamailio Behind TCP Load Balancer
by Colin Morelli 04 Jun '18

04 Jun '18

Hey all, I'm looking to put Kamailio behind a TCP load balancer that is SIP-unaware. My application is deployed in AWS and I'm tying to place Kamailio behind an ELB. For the most part, everything is fine. For my specific implementation I'm disabling UDP as a signaling transport and using only TLS. This enables me to not have to worry about a SIP-aware LB at the edge because replies to an incoming request will be sent over the existing established TCP socket (avoiding any crazy routing … [View More]

Determining next hop for any SIP message
by George Diamantopoulos 07 May '18

07 May '18

Hello all, I've been trying to figure out a cleaner way to determine the next hop for a SIP message, mainly for use within the NATMANAGE route for multi-homed kamailio instances (with three or more network interfaces on the kamailio host). So far I have achieved this with a series of nested ifs, depending on whether the message is a request or a response and by calculating the next hop based on the various headers (R-URI, Route) and variables ($T_req($Ri), $dd, ) involved in SIP routing. A … [View More]

by Kjeld Flarup 07 May '18

07 May '18

Hello I have a question to those of You who uses push via Google or Apple to initiate calls. How long time does it usually take, before the phone gets the push and wakes up?

MSILO: Message limit on SIP stored offline MESSAGE delivery
by Abdul Basit 04 May '18

04 May '18

Hi Team, I have setup IM server with kamailio using MSILO module. Its working fine now. I have a scenario where lot of offline messages are being stored in mysql database for a user B.

Is there any way, where I can … [View More]

DMQ and/or Database for dialogs, registrations, etc..
by Joel Serrano 03 May '18

03 May '18

Hi all, Just wanted to know what your opinions were on using DMQ modules over database for things like dialog replication, registrations, etc... Is DMQ the "new way to go"? I know that there lots of ways of doing things with each having pros/cons... But I was wondering... What does the community think on this topic? Are you guys taking advantage of the DMQ modules or are you still relying on database as much as possible? Maybe a combination of both? Cheers, Joel.

Send UPDATE to inform changes in SDP
by Alfonso Pinto 30 Apr '18

30 Apr '18

Hi guys, I'm trying to setup a Call Forward No Reply with Kamailio and I've run into this problem (that was expected): When A INVITEs B, B replies with 183 and some SDP. B doesn't answer so Kamailio triggers the timeout and sends the INVITE TO C. C replies with 200 OK and some SDP, but A side drops the call as the media session doesn't match with the expected one. To solve it, I'm trying to send to A an UPDATE before relaying the 200 OK from C. I tried to use UAC module (uac_req_send + $… [View More]
