Call flow for Scenario 3 - local call
1 The branch office user dials 43456. The system transmits 43456 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 43456 to the main office.
3 The main office determines that this is to another branch office, with
office prefix 552. The system inserts the prefix and transmits 552-43456
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 sends the call to 552-43456 to the branch office. The
branch office deletes the prefix and LSC "4", and rings set 3456.
