Call flow for Scenario 1- local call
1. The branch office user dials 6-395-3456. The system transmits
399-3456 to the branch office user dials 6-399-3456. 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 399-3456 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
552-399-3456 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 552-399-3456 to the branch office. The
branch office deletes the prefix and the HLOC, and rings set 3456.
Call between branch offices associated with different main office
The following scenarios describe calls between two branch offices that
belong to different main offices. Note that the different scenarios described
below vary in the manner in which the HLOC is architected; branch offices
have same HLOC as the main office, branch offices have a different HLOC
than the main office and so on.
