Region Provisioning detail
1 All branch offices are provisioned at the NRS to route all calls
through the main office.
1 Main office sends all CDP calls to destinations that are not its
own Branch Office to the NRS with unchanged dialled digits.
1 Main office sends all CDP calls to destinations that are its own
Branch Office to the NRS with a specific gateway prefix in front
of the dialled digits.
1 All branch offices delete the prefix and terminate the calls. May
be to a local set or to a trunk.
2,3 Similar configuration, as above, applies to regions 2 and 3.

Figure 45 "Call flow for Scenario 3 - local call" (page 117) shows the call
flow of a call between two local branch offices.
Figure 45
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
