Location Validation and Call Level Security

Location validation employs various callback methods to confirm a user's location. One of these methods, CLI (Caller Line ID) validates an incoming call number against an internal database of approved numbers. CLI allows for the validation of ISDN calls by providing the called site with the ISDN telephone number from which a call is being made. This allows the called site to verify that the call is coming from an authorized location.
