Looks like you're making an RTP/SAVPF offer to a client that speaks
RTP/AVPF only, and you're neglecting to instruct rtpengine to do any
translation between the two. The solution is to include the "RTP/AVPF"
flag in the offer.

There's also a stray "delete" in there, which you may want to eliminate.
It's harmless as it is, but it probably shouldn't be there.

Cheers
