Title: Real-Time Transport Protocol (RTP) Payload Formats for the Variable-Rate Multimode Wideband (VMR-WB) Audio Codec

This document specifies a real-time transport protocol (RTP) payload format
to be used for the Variable-Rate Multimode Wideband (VMR-WB) speech codec.
The payload format is designed to be able to interoperate with existing
VMR-WB transport formats on non-IP networks. A MIME type registration is
included for VMR-WB RTP payload formats. VMR-WB is a variable-rate
multimode wideband speech codec that has a number of operating modes, one
of which is interoperable with AMR-WB (i.e., RFC 3267) audio codec at
certain rates. Therefore, provisions have been made in this draft to
facilitate and simplify data packet exchange between VMR-WB and AMR-WB in
the interoperable mode with no transcoding function involved.
