Hello,

 

I noticed an interop issue when using a Bria softphone and inbound-bypass-media is true in the sip_profile.  When answering an inbound call, the Bria softphone's SDP Answer includes the list of codecs it supports (audio and video).  I noticed that, even in bypass media mode, Freeswitch filters out all of the codecs in the list after the first one.  I think this is not right.  According to RFC 3264 (Section 7 Offerer Processing of the Answer), it is valid to provide a list of codecs in an SDP Answer and the endpoint SHOULD use the first one (but it might not).

 

Why is Freeswitch altering the SDP in the 200 OK?  I think it should send the SDP unmodified.

 

Thanks,

Jerry
