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.
It does not specify an Internet standard of any kind. Discussion and
suggestions for improvement are requested. Distribution of this memo
