[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 SDP offer and answer. This document provides the offer/answer considerations for these parameters and updates [RFC4856].
