Debugging DTMF and/or One way Audio

Jump to solution

2 part question.

Is there anyway to run a debug to try and capture DTMF for an Active voice call after the call has been set up? Be it analog OR pri?

Also is there anyway to debug to see the individual RTP streams on a phone call for example to investigate one way audio?

I tried debugging UDP but RTP doesnt show up in the debug.

No problem.

If you want to debug out-of-band/RFC 2833 DTMF tones, use this command:

"debug voice dsp voip 0/X channel verbose rfc2833"       //where X is the DSP the call is on when you are in a 2 DSP unit

You will be able to see any out-of-band DTMF in the debug.

Geoff

I find the easiest way to debug these issues is to use WireShark.

You will need a hub or a switch with port mirroring.

Hello and thanks for posting to our forum.

1.  Are you doing inband or out-of-band DTMF?

2.  If you issue the command 'show media summary' you can see active calls going through the DSP in the TA 900.  From there, you can issue the command 'show media session 0/X.Y' where X is the DSP and Y is the channel shown in the media summary.

Let me know if you have any more questions.

Regards,

Geoff

Thank you Geoff. The one way audio commands you gave look like they will be very useful.

As far as DTMF lets assume out of band but if you have a way for inband I would be interested in knowing that as well.

Thanks again.
