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. It is not applicable to SIP VP-T49G IP
phones.
