Technical Summary This document specifies real-time transport protocol (RTP) payload formats to be used for the EVRC wideband codec (EVRC-WB) and updates the media type registrations for EVRC-B codec (RFC 4788). Several media type registrations are included for EVRC-WB RTP payload formats. In addition, a file format is specified for transport of EVRC-WB speech data in storage mode applications such as e-mail. Working Group Summary The document has been reviewed by the AVT working group to ensure consistency with RFC 4788 media type registration, and meets the necessary requirements to for payload type specification. Document Quality The draft has existing implementation and is required for 3GPP2. The request for review of the media type in the ietf-type list was posted on May 24, 2007. Personnel Roni Even is the document shepherd.
