This document describes a method to improve the bandwidth
utilization of RTP streams over network paths that carry multiple
Real-time Transport Protocol (RTP) streams in parallel between two
endpoints, as in voice trunking. The method combines standard
protocols that provide compression, multiplexing, and tunneling over
a network path for the purpose of reducing the bandwidth used when
multiple RTP streams are carried over that path. This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements.
