PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9,
followed by 1, and then the 10-digit number. Both sites use MGCP gateways. AAR must use
globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are
localized at the egress gateway as shown in the exhibit. Which statement is true?
