[Asterisk-Users] DTMF Modes

[Eric Wieling]

I am seeing a 101 telephone event, but only when I get a ringback, not
when I press the touch tones.

I think I have my ATA186 set to use OOB DTMF and I have dtmfmode=rfc2833
in my sip.conf.  Does ANYONE have ANY idea how I can continue to
diagnose the problem from here?
