This codec offer interface provides a method of signalling support for RTCP feedback, documented by Extended RTP Profile for Real-time Transport Control Protocol (RTCP)-Based Feedback (RTP/AVPF) (RFC 4585).

The codec identifiers used in the description of the Feedback Messages sent in the Accept's should match those used for the RemoteCodecs in the same Accept call.

For more details on what RTCP Feedback can do and how to use it, one should refer to RFC 4585.

A map of remote feedback codec properties that are supported. True if the remote contact supports Audio-Visual Profile Feedback (AVPF), otherwise False.
