How It Works
1. When a switch receives a terminating call, the switch
determines if these criteria are satisfied: the terminating subscriber
has activated Caller ID, the call is not marked as restricted, and the
calling party is available.
2. If all three are satisfied, the switch launches
a query to a VeriSign STP which performs global title translation (GTT)
and determines the appropriate calling name database (SCP).
3. The query routes to the appropriate SCP, which accesses
name information in its corresponding calling name database.
4. The SCP provides a response that includes the calling
party’s name, city and state information, and privacy indicator.
