This document describes how to carry 64 kbit/s channel data transparently in RTP packets, using a pseudo-codec called "Clearmode". It also serves as registration for a related MIME type called "audio/clearmode".

"Clearmode" is a basic feature of VoIP Media Gateways.

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

This is now a Proposed Standard Protocol.
