FreePBX has this functionality... they call it "Confirm Calls"

I;m not sure if you can set it on actual extensions, but I know you can set it on ring groups.

I don't imagine the dialplan for doing it is very complicated if you wanted to do it by hand.

Subject: [asterisk-users] Anyone Know How to Have Asterisk Work Like GranCentral and Require a Touch-Tone to Connect?

GrandCentral has a feature where when you call the GrandCentral number it can ring multiple phones. However, it's not the first phone to answer that gets connected, but the first phone to answer AND play a touch-tone after hearing a recording. The advantage of this is that if one of the called phones has voicemail, it won't get connected to the calling party because the VM won't send a touch tone in response to the recording, unlike a live person.

I have always resisted implementing a multiple ring scenario with Asterisk that included a cellphone because of the voicemail answering problem, but this seems to be a solution.

Anyone know how to implement it with Asterisk?

I just took a quick look at the dialplan that freepbx uses for doing call confirmation... the dialplan part of it is actually quite simple... its just a matter of setting the USE_CONFIRMATION varialbe =TRUE.

However, the actual magic looks like it happenes through its dialparties.agi... which is a little more complicated than i'd like to try and dissect on a sunday afternoon!

but that might be a good place to look at how its done to learn by example.

I know in the freepbx implementation what it does is whenever a handset thats part of the ringgroup answers, they get a recorded message "You have an incoming call, press 1 to accept" maybe it says something else too... can;t recall at the moment. The first member of the Ring group to hit 1 gets the call... if more than 1 person picks up the handset right away, the first to hit 1 gets it, and the rest hear a "sorry, too late, somebody else got it"-type message (no idea what it actually says).

For zap channels, you do have the "c" option on the dialgroup which
requires that you press # before the call is connected.

Works great for my mobile
