Hi Patrick,

Are you using analogue phones connected to your asterisk box (directly
or through a channel bank)? Because it looks from the code as if that
is the only situation where those codes are captured by the chan_zap
driver and processed specially.

If you want to disable them, just insert an 'x' into the string, or some
other non-DTMF character. Then the strcmp will never match:

} else if (!strcmp(exten, "x*0")) {

Cheers
Tony
