Forced Authorization Code in CUCM

Forced Authorization Code (or FAC) is a flag that can be configured at the route pattern level. When it is set on the route pattern, the route pattern is said to be associated with an authorization level.
An authorization level is a numeric string that can be up to 16-digits long, and whose value may range from 0 to 255.
Forced Authorization Code is a postscript; it is run after CUCM selects the BestMatch route pattern.
With FAC, after CUCM chooses the BestMatch, if the route pattern has the FAC flag enabled, CUCM plays a seond dial tone. The user enters an authorization code. If this authorization code is greater or equal to the authorization level associated with the route pattern, then the call can be routed. Otherwhise (less than tha authorization level), the call can not be routed.
Let’s suppose that the user-inserted authorization code is greater or equal to the authorization level associated with the BestMatch route pattern: in this case, the user must dial the pound key (#)or interdigit timer must expire for CUCM to route the call.
