<p class="MsoNormal" style="margin-bottom:12.0pt">Maybe bind_digit_action would capture these for you. You could try binding something simple, like a log function:<br>
<br>
<action application="bind_digit_action" data="rogue_dtmf,~\w+,exec:log,INFO Rogue digit(s): ${last_matching_digits}"/><br>
<action application="digit_action_set_realm" data="rogue_dtmf"/><br>
<br>
You'll need to experiment to make sure that regex works. If not you could possibly do each digit explicity, like this:<br>
<action application="bind_digit_action" data="rogue_dtmf,A,exec:log,INFO Rogue digit: DTMF 'A' received"/><br>
<action application="bind_digit_action" data="rogue_dtmf,B,exec:log,INFO Rogue digit: DTMF 'B' received"/><br>
<action application="bind_digit_action" data="rogue_dtmf,C,exec:log,INFO Rogue digit: DTMF 'C' received"/><br>
<action application="bind_digit_action" data="rogue_dtmf,D,exec:log,INFO Rogue digit: DTMF 'D' received"/><br>
<br>
I don't honestly know if this will work, but I'd like to see what happens in your case. FYI, you can read up on bind_digit_action (AKA 'bda') here:<br>
