[OpenSIPS-Users] Handling SDP on 302 request with mhome

[Bogdan-Andrei Iancu]

Hi Antonis,

I guess you should move the enagaing of the rtpengine (for the INVITE 
time) in the branch route, so it can do different SDP settings according 
to the destination of that branch.

How you do it now will set the SDP in INVITE only in relation to the 
first branch (so WAN) and reuse it for the next branches too.

Best regards,
