Please I need your help, I have been working to solve a script for AA for 3 days by now, and when I solved it, it ended with me facing another problem:
Call from Outside -> FXO -> AA
If someone called and hanged off the line, AA still running and for sure the port is hanged.
Call from Outside -> FXO -> AA-> Extension
If the caller dialed the extension and got transferred, then the Called side phone keeps ringing and never got disconnected, the port hangs.
Call from Outside -> FXO -> AA-> Extension->Voicemail
If the caller dialed the extension and got transferred, then the Called side phone keeps ringing until no answer timer reached, the call transferred and again, the port hangs.
FXO port is always hanged.

I really need your help guys. I have tried everything, batter reversal, supervisory disconnect, timeout call-disconnect, timeout wait-release,
I am out of ideas. Any Help?
There's a really quick test you can do. Place a call through the FXO to an extension. Hang up on the PSTN, stay off hook on the IP phone. Listen and see if you hear tones. If you hear tones, the provider is using a disconnect tone to disconnect the call.
This is a post I wrote up to help configure what you need if this is the case:
