Hi! Our telco routes multiple numbers through PRI to our Asterisk. Not all of these numbers are in use. I have noticed recently that someone keeps calling unused phone number from outside world. I called them and asked why do they call dead number. The person on the far end explained that she keeps calling this number because she hears "busy" tone every time... Most telcos these days provide verbal in-band notification in case if number does not exist. Those nice female voices. People do expect this behaviour from their phones. People no longer accept beeps as "number does not exist" signal. First thing I've tried was Playback(invalid). The problem was that asterisk answered incoming call. This should not happen when caller does not reach his/her destination. Next, I tried Playback(invalid,noanswer). This time, Asterisk did not answer the call. But there was no sound! Apparently, Playback(invalid,noanswer) does not work with Zap/PRI. Is this bug?

[Asterisk-Users] Playback(something,noanswer) on Zap?

However, if your telco will not allow you to send 'early audio', then you can't do it. A better solution is to set the PRI hangup cause before dropping the incoming call; if you set the hangup cause to 'number not assigned' then your telco's switch will play its normal intercept message to the caller.
