Call flow for Scenario 1 - call to remote branch office (destination side)
1 Main office B determines that LOC 444 is to a local branch office with
prefix 225. The system transmits 225-444-3456 to the NRS. The NRS
checks its provisioning, and determines that this call goes to branch
office B1.
2 The main office sends the call to 225-444-3456 to the branch office. The
branch office deletes the prefix, discovers the call is to its HLOC, deletes
the HLOC, and rings set 3456.
Use Procedure 5 on
1 Enter the main office Gateway endpoint identifier in the Tandem
Endpoint field for each branch office gateway configured on the NRS.
This provides tandeming for outbound calls from a branch office through
its main office. See step 1 on
2 Plan the gateway routing prefixes, if not already done. 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.) See step 2 on
