The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and
video over IP networks. The UDP port used for RTP streams is traditionally an
even-numbered port. For example, the default RTP min port on the IP phones is 11780.
The first voice patch sends RTP on port 11780. Additional calls would then use ports
11782, 11784, 11786, etc up to the max port.
Procedure
RTP port can be configured using the configuration files or locally.
