I want to do some testing of DTMF detection on PRI which is another beast.
My setup is 1.6.1, couple of SIP softclients and 2 Digium PRI cards. My PRI link is looping basically to myself.
I can make calls out the PRI interface without issue. They loop back into my simple autoattendant and is able to recognize and print the DTMF digits pressed in the console.
My external DTMF detector is not seeing the DTMF but that is another story. When I config DTMF=inband on my clients I can hear DTMF fine when calling just user to user without going through the PRI card. When I dial my extension that routes the call through the PRI interface and back again there is minimal if not broken DTMF between clients.
I have done alot of searching and am coming up empty here. Any guidance appreciated and I can post *.conf files as needed. Would simply like an easy way to generate a call and play DTMF across the PRI for other testing purposes.
