I have a strange problem with my ephones with enabled VT Advantage. Ephone always setup RTP stream using UDP port 1684. I setup VT Advanate, and after that I found that ephone use random UDP port for RTP. How can I set one ore some port range for it? I don't want to permit all UDP packets to/from ephones for security reasons.
There are 796(0,1,5) cisco ip phones. I don't know what type of traffic in this RTP. One things that I want - to understand, why with enabled VT outgoing RTP traffic started from random port in range 16284-32000, and without VT it started always from 16384.
