DTMF A-D is not normally available by normal people. They're perfect for ADSI phones to use to initiate some kind of command since they do not get in the way of Joe's VoiceMail Service -- right now we seem to use * and # a lot, but so does everyone else. How do you "escape" these keys so that the far end can detect and use them? That's why I suggested using DTMF A-D to control asterisk with ADSI. I am fairly certain you can say Dial(Zap/1/D) and get the D tone.... I think. :-) It's be trivial to do if not, but I'm not so much looking at * to generate the tones as just detect them and have the ADSI phones generate them. Muting from the far end -- after reading it that way I think I see your confusion. :-) What I'd meant was that *, upon "hearing" one of these DTMF tones, mutes the channel so that the far end doesn't hear it, or rather hears a very (under 1/10s) short burst of it. It'd be both a security feature and a just plain nice feature, since when I'm transferring someone or calling up some feature on my ADSI phone while talking to someone, I'd prefer not to blast them with DTMF. :-) Hopefully that clears up what I'd been talking about. :-) Regards, Andrew > > _______________________________________________ > Asterisk-Users mailing list > [EMAIL PROTECTED] > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
