To implement toll fraud prevention on Cisco UCM, an administrator can use the following parameters:
Enable Forced Authorization Code 112211.
Set an authorization level of 3 for the route pattern 8005551212.
Require no access code to dial 10-digit numbers.
The route pattern must be implemented as follows:
Pattern = 1122113.8005551212
This will require users to enter the authorization code 112211 followed by the number 8005551212 to dial this number. The authorization level of 3 will prevent users from transferring calls to this number.
