Call flow for Scenario 1 - call to remote branch office (destination side)

1Main 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.

2The 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.

Summary of provisioning procedures for Tandem Bandwidth Management

Use Procedure 5 on page 110 to provision the network.

1Enter 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 page 110.

2Plan 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 page 111.
