Technical Summary

This document specifies the payload format for packetization of the
GSM Half-Rate speech codec data into the Real-time Transport Protocol

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.
