    abstract =  {The Real-Time Transport Protocol (RTP) is a multi-point protocol, supporting multiple simultaneous sending sources in an RTP session. However, many existing RTP endpoints cannot usefully receive more than one simultaneous source. This document provides a Session Description Protocol (SDP) attribute that allows endpoints to indicate the maximum number of sources they can usefully receive.},
