How It Works

1. Unidentified roamer places call from wireless phone.
2. Local carrier’s switch receives call and recognizes it as an unregistered roamer.
3. The local switch sends call to VeriSign on-site processor where call stays while ARN processor accesses ARN database via high-speed data links.
4. ARN database performs velocity checks and fraud mitigation processes.
5. ARN database performs credit card validation or collect call approval.
6. Once validation is complete, approval for the call is sent back via data links to VeriSign processor.
7. Call is sent to switch where it is connected through the PSTN.
