  "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.
