In the CCA 2.2.5 PCM Capture feature, I can enter '50/0/10' into the "Voice Port" and generate pcm.dat.
However the CLI 'test voice port' command does not accept '50/0/10'. What is the correct CLI syntax to use ?
<0-50> Voice interface slot #
<0-0> Voice interface SubUnit #
<5-56> Voice interface port # within vic
UC520#test voice port 50/0/10 ?
% Unrecognized command
I am using ver.15.0(1)XA3a.
Any voice port that starts w/ 50/x/x are virtual voice ports representing the IP phones (ephones). Although they are "voice-ports" from CME's perspective they are not your traditional voice ports that invoke a DSP since that call leg is IP. Since there are no DSP's invoked from CME's perspective you can't capture PCM traces for voice ports that start w/ 50/x/x. The PCM tool is a DSP specific tool. If you want to capture an audio sample of a call for the call leg of the IP phone you can use Wireshark, Cain & Able, Commview, etc.
Another note is that once you create a valid PCM.dat file you need to open a TAC case and have them decode the file for you.
