Real-Time Transport Protocol (RTP) Ports
You can specify the IP phone’s RTP port range. Since the IP phone supports conferencing and multiple RTP streams, it
can use several ports concurrently. The UDP port used for RTP streams is traditionally an even-numbered port. For
example, the default RTP min port on the phones is 11780. The first voice session sends RTP using port 11780. Addi-
tional calls would then use ports 11782, 11784, 11786, and so on. The phone is compatible with RFC 1889 - RTP: A Trans-
port Protocol for Real-Time Applications - and the updated RFC 3550 .
It is only applicable to CP960 phones.
