Technical Summary RFC4856 describes the annexa parameter for G723 and the annexb parameter for G729, G729D and G729E. However, the specification does not describe the offerer and answerer behavior when the value of the annexa or annexb parameter does not match in the Session Description protocol (SDP) offer and answer. This document provides the offer/ answer considerations for these parameters and updates RFC4856. Working Group Summary There is WG consensus behind this draft. All issues raised during and before WGLC have been addressed. Document Quality This document clarifies behavior with the discussed SDP parameters to be in line with existing specifications and pragmatic implementations. The document has been discussed in MMUSIC, PAYLOAD, and AVTEXT working groups and has been revised according to the feedback. Personnel Who is the Document Shepherd?
