	Title		: RTP Payload Format for EVRC and SMV Vocoders

This document describes the RTP payload format for Enhanced Variable
Rate Codec (EVRC) Speech and Selectable Mode Vocoder (SMV) Speech.
Two sub-formats are specified for different application scenarios. A
bundled/interleaved format is included to reduce the effect of packet
loss on speech quality and amortize the overhead of the RTP header
over more than one speech frame. A non-bundled format is also
supported for conversational applications.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
