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.
