Using ARS to restrict outgoing calls
ARS allows you to block outgoing calls to specific dialed strings. For example,
you can restrict users from making international calls to countries where you do
not do business, or in the U.S. you can restrict access to 900 and 976 pay-per-call
numbers.
!SECURITY ALERT:
To prevent toll fraud, deny calls to countries where you do not do business.
The following countries are currently concerns for fraudulent calling.
