Capturing DTMF

Is there an efficient way to capture DTMF ? I have enabled SIP debugging with verbosity 10 but to no avail.

It looks as if it is completely lost. The IVRs and other voicemail menus seem to be ignorants to my key strokes.

I’ve been playing with various options for dtmfmode = (auto,rfc2833,inband,info) but no use. I was wondering if there was a tool that would help me detect dtmfs ?

I’m assuming you mean from a sip trunk.

step one. Talk to your sip provider and find out how they are providing dtmf to you.
