Appendix - RTP/RTCP Payload Types

Latest RTP Payload Types are defined in RFC 3551. For coders that should have
dynamic Payload types, proprietary default values have been defined. These defaults
are appropriate when working with AudioCodes products only. However, it is
recommended to set a dynamic Payload type for them, which is usually done by
higher applications during call setup. Be sure not to overload dynamic Payload types.
