Appendix C RTP/RTCP Payload Types and Port
RTP Payload Types are defined in RFC 1889 and RFC 1890. We have added new payload types
to enable advanced use of other coder types. These types are reportedly not used by other
applications.

C. RTP/RTCP Payload Types and Port Allocation
Basic Packet Rate [msec]
Randomly, approximately every 5 seconds (when
packets are sent by channel)
Randomly, approximately every 5 seconds (when
channel is only receiving)
Basic Packet Rate [msec]
Same as channel's voice coder.
