This document specifies a speech codec suitable for robust voice
communication over IP.  The codec is developed by Global IP Sound
(GIPS).  It is designed for narrow band speech and results in a
payload bit rate of 13.33 kbit/s for 30 ms frames and 15.20 kbit/s
for 20 ms frames.  The codec enables graceful speech quality
degradation in the case of lost frames, which occurs in connection
with lost or delayed IP packets.

This document is a product of the Audio/Video Transport Working Group
of the IETF.

This memo defines an Experimental Protocol for the Internet community.
