Can you elaborate upon how you'd take advantage of DTMF A-D, how you'd produce the tones (are these standard now?), and what exactly you mean by "muting from the far-end"?

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 > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users

I have several phones that have A-D on them. Which I'm sure is where the original poster would want far-end muting capability (no need to blast DTMF into a conference call for all to hear when you are performing control functions on the call). Whether this is the best way to do things today, especially in hybrid environments is another discussion. My personal preference is to see those nasty things (all in-band signaling, for that matter) die off in favor of more modern control methods made much more accessible with SIP phones and large, programmable displays with soft buttons.
