UAC must send ACK with SDP (specifying that media (audio/video/image) port to 0). For details please refer to: http://tools.ietf.org/rfc/rfc4317.txt

UAS replies with a offer in 200OK. Now this 200OK has codec's which UAC doesn't support. Now ideally how should UAC respond? What should be the response if this INVITE is a reINVITE w/o SDP ?
