Technical Summary This memo specifies an RTP profile that combines the features of SRTP (SAVP) and the Extended Profile for RTCP-based Feedback (AVPF). Thus allowing SRTP's security functions, encryption and integrity protection to be used in session which requires more timely RTCP feedback than what AVP provides. Rules for how multiple profiles may be offered in SDP under offer/answer are also defined. Working Group Summary There is consensus in the WG to publish this document. Protocol Quality The combination of the two profiles are basically orthogonal. Thus no new algorithms or other advanced features was needed to be define for this profile. The main new functionality is the signalling solution which has been reviewed both in AVT and MMUSIC.
