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.  [STANDARDS TRACK]
