How to FAC timeout to 10sec on CallManager 7
1. A user dials a number that goes to a FAC-enabled route pattern.
2.Cisco CallManager tells the phone to play a special tone.
3.The user enters the authorization code. The system then either waits for the FAC Timer (T302/ or interdigit timer) to expire (default 15 seconds) or for the user to press the "#" key.
Note: Since the FAC timer affects T302 timer, bear in mind that if you adjust this timer to permit more time for FAC input, it extends the time for normal calls as well.
4. If the code is correct, the call is extended to the exiting gateway and Cisco CallManager generates a Call Detail Record (CDR) flagged with the FAC number.
