RTP Payload Format and File Storage Format for the Adaptive Multi- Rate and Adaptive Multi-Rate Wideband Audio Codecs
RFC 4867, “RTP Payload Format and File Storage Format for the Adaptive Multi- Rate and Adaptive Multi-Rate Wideband Audio Codecs”, is a Proposed Standard document published in April 2007 by J. Sjoberg, M. Westerlund, A. Lakaniemi, Q. Xie. It obsoletes RFC 3267. The canonical text is published by the RFC Editor.
Abstract
This document specifies a Real-time Transport Protocol (RTP) payload format to be used for Adaptive Multi-Rate (AMR) and Adaptive Multi-Rate Wideband (AMR-WB) encoded speech signals. The payload format is designed to be able to interoperate with existing AMR and AMR-WB transport formats on non-IP networks. In addition, a file format is specified for transport of AMR and AMR-WB speech data in storage mode applications such as email. Two separate media type registrations are included, one for AMR and one for AMR-WB, specifying use of both the RTP payload format and the storage format. This document obsoletes RFC 3267.

What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
