parallel fork of calls with same Call-ID about rtpengine HOT 3 CLOSED

Closing as this is already being handled on the kamailio mailing list

from rtpengine.

Hello !

I would like to know if this issue is solved sipwise/mediaproxy-ng#23
in rtpengine code. It seems to be related to this issue, so.

My test is very simple, I have 2 endpoints connecting to the same username (201). One using TLS/SRTP, the other one using UDP/RTP.

If I call 201, the 2 endpoints ring but I can see that rtpengine overwrites the offer of the other one. And finally got this error: "SRTP output wanted, but no crypto suite was negotiated"

I use the kamailio-advanced.cfg provided with default installation of kamailio(4.2.0). And I think lookup(location) doesn't work with rptengine even if modparam("registrar", "append_branches", 1).

kamailio seems to reuse same callid and branch value for the 2 calls, so rtpengine can't detect 2 sessions.

@ovoshlook, this is why you don't use lookup(location) and build manually the branches ?

Thank you !

I not use lookup becasue I use WebSocket based endpoints and kamailio can
not resolve contact field data fro this endpoints. I use received field to
set Destination URI for this endpoints. so I need custom query to database
for finding this endpoints.
