I can't think of a single place where, if an app is to be run, that Asterisk would be listening for DTMF. Menu selections are listened for, after the 's' extension is finished running. DTMF for features, during a bridge (like in Dial). In Dial, you can run a macro/gosub, but that's on the peer channel, and before the call is bridged. Nope, such an app would be useless. The only times this code would be useful, is for instance, in a channel driver, while a bridge is in effect. (see chan_sip.c; this kind of code is run when the SNOM360 "Record" button is hit, for instance.) murf -- Steve Murphy Software Developer Digium
