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

[Matt Watson]

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.

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?
