Technical Summary

This document specifies the payload format for packetization of the
GSM Half-Rate speech codec data into the Real-time Transport Protocol
(RTP).  The payload format supports transmission of multiple frames
per payload and packet loss robustness methods using redundancy.

Working Group Summary

No major issues were raised during the document's progress through the
Working Group.
