Abnormal case - calls originating using UDP, but terminating
using CDP

Figure 58
Call flow for Scenario 2 - local call dial UDP

1. The branch office user dials 6-395-3456. The system transmits

395-3456 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 395-3456 to the main office.

3. The main office determines that this is to another branch office, using

CDP. The system deletes the HLOC and transmits 3456 to the NRS.
The NRS checks its provisioning, and determines that all calls to 3456
from this CDP region are to be sent to branch office A2; it directs the call
to the branch office.

4. The main office sends the call to 3456 to the branch office. The branch

office rings set 3456.
