If you're looking to block all users, change your ARS ANA from allowing the call to go. If your looking to limit some users, look at using your FRLs to do this. You can send the calls to a new route pattern with a higher FRL, this would control the access to international calls. The users that are aloud to make the call need to have the same FRL as the international route. Look!!! New Buttons
Same amount of time!
