[asterisk-dev] Zaptel DTMF regeneration

[Moises Silva]

Take your time to read the code. The places I pointed out to you are
the correct ones, at least for detection of DTMF, the routine
ast_dsp_process takes care of that. If you want to see the very
working of the Goertzel algorithm used you could have found so by
checking that routine and seeing that calls dtmf_detect which does the
actual DTMF loop detection.

As of the audio mute, not sure what you mean?
