For some reasons the confirm calls is not working, when the phone ring an outside extension and the receiver get the greeting "You have an incoming call press 1 to accept and 2 two decline". Whenever we press 1 the call automatically hang up. I did some research some are saying it is a bug in asterisk and other are saying you need to replace the announcement with your own recording. I did replace the system recording with my own that still did not help. I will greatly appreciate any help i can get. Thanks.
