Does anyone know if it is possible to do the following with asterisk...
there are 2 users, John and Betty
John calls -> asterisk accepts the call
asterisk dials Betty and asks for DTMF input(accept/decline)
DTMF from Betty
3(a) Betty presses 1(accept) -> asterisk connects Jon+Betty
3(b) Betty presses whatever except 1 or hangs up -> John hears sound "Betty does not want to talk to you" and is disconnected too.
Not sure how can explain it more clearly...
any help would be greatly appreciated.
