Call flow for Scenario 1 - local call
1. The branch office user dials 6-395-3456. The system transmits
395-3456 to the NRS. The NRS checks its provisioning, and determines
that all calls are to be sent to the main office; it directs the call to the
main office.
2. The branch office sends the call to 395-3456 to the main office.
3. The main office determines that this is LOC 39534 to another branch
office, with gatewayrouting prefix 552. Thesystem inser tsthe prefix and
transmits 552-395-3456 to the NRS. The NRS checks its provisioning,
and determines that all calls to prefix 552 are to be sent to branch office
A2; it directs the call to the branch office.
4. The main office sendsthe call to 552-395-3456 to the branch office. The
branch office deletes the prefix and the HLOC and rings set 3456.
No branch office HLOC is shared with the main office or another branch
office In this example, the HLOC is unique betweenall the branch offices and the
main office. See Figure 47 "Call flow for Scenario 1- local call" (page 137).
