Debugging DTMF Sip -> PRI -> SIP

Jump to solution

Edited Title to better reflect question.

Hello, I'm relatively new to the Adtran products.  I'm using a TA904 as a SIP to PRI Gateway.  My Setup is Handset ->SIP -> Asterisk -> PRI -> Adtran - > SIP -> Carrier.  I'm having DTMF Issues when calling from the asterisk box out to the carrier.  Calls Inbound, from the carrier to the Asterisk box can navigate my IVR Properly.  This is a test setup, that is why the Sip Carrier does not connect directly to the Asterisk box.  I'm testing this to be able to provide Voip Termination via PRI to legacy PBX Products.

I'm running the DTMF Debug options on both the Asterisk box and the Adtran, but I'm having some issues deciphering what the Adtran Output is telling me.  I used the command 'debug voice dsp voip 0/1 channel verbose rfc2833'

Below is the example when Entering my zip code into an IVR out on the PSTN (60505)  It looks like the Adtran is seeing the DTMF Event over the PRI correctly, but I'm not sure exactly what it's telling me.  It's acting like the remote end is getting multiple Keypresses for each digit.

Thank you,

Nate

Re: Debugging DTMF Sip -> PRI -> SIP

Jump to solution

This looks OK. What is happening on the carrier side? Do they not react to DTMF at all, or does it appear as multiple digits?

Is the carrier side set up for DTMF inband or RFC2833?  Are you using G.711 codec to the carrier?

When you dial an IVR and send a single digit, does it interrupt the greeting? This will tell.

You set it on the codec group for the ISDN voice trunk.

If you always use G.711 and get double digits it's possible that there is some early detection of the inband tone as well as the RFC2833 relay. You might set to inband if G-711 only but this will fail with G.729.
