This document updates the Enhanced Variable Rate Codec (EVRC) RTP
payload formats defined in RFC 3558 with several enhancements and
extensions. In particular, it defines support for the header-free
and interleaved/bundled packet formats for the EVRC-B codec, a new
compact bundled format for the EVRC and EVRC-B codecs, as well as
discontinuous transmission (DTX) support for EVRC and EVRC-B-encoded
speech transported via RTP. Voice over IP (VoIP) applications
operating over low bandwidth dial-up and wireless networks require
such enhancements for efficient use of the bandwidth. [STANDARDS TRACK]
