2 Plan the gateway routing prefixes. At least one prefix is needed per
branch office, although any branch offices that have a prefix for ESA “911”
calls does not necessarily require another. (These prefixes will be SPN
- Special Number - entries if you are using ESA 911. In the example these
are LOC codes because network 911 is not being used.)
In our example the Branch office prefixes are 741 (branch office B) and
742 (branch office A).
3 Provision the NRS to send all calls to a LOC without a gateway routing
prefix to the main office of that LOC, or to the main office which provides
service for the branch office using the LOC. In our example the NRS is
provisioned with 841 (for main office B) and 842 (for main office A).
4 Provision the NRS to send all calls to a LOC with a gateway routing prefix
to the branch office directly. Using the gateway routing prefix and the
Type of Number as used (LOC or SPN), the entries can be differentiated
from the normal LOCs easily.
In our example the NRS is provisioned with 741-841 at branch office B
and 742-842 for branch office A.
