UCME rtp port

I`ve noticed that all the rtp sessions to UCME phones (SCCP ones) has udp src port 2000. I mean not only tcp control connection for SCCP goes from port 2000, but all the actual RTP streams also.

Our call recording applications is not happy with it, as it guess that same RTP endpoing should use unique rtp ports.

Is there way to change rtp port selection in SIP-like method? So that it will use 16384..32767 ports range?

Re: UCME rtp port

Does your recording vendor officially support CME?

I have used many diffrent type, all do work, none has an issue with the port numbers.

no, officialy it doeasn`t support cme officialy as it`s an opensource call recording app - oreka.

But there is no that kind of problem with UCM, and sccp there works perfectly.
