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 out of the dynamic Payload type range have been
defined. These defaults are appropriate when working with MG 3200 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.
