RFC 4788: Enhancements to RTP Payload Formats for EVRC Family Codecs

Still current, but amended. Parts of this document are changed or extended by RFC 5188. Read both.

In plain English — editorial summary, not part of the RFC

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]
