Call Scenarios

This section describes the following call scenarios, all based on

Figure 122

"Group Dialing Plan (GDP)" (page 393)

:

"From main office to Branch Office using CDP" (page 393)

"From main office to Branch Office using UDP-LOC" (page 394)

"From Branch Office to main office using CDP" (page 394)

"From Branch Office to main office using UDP-LOC" (page 394)

"Branch User telephone (DN 3002) is in Local Mode" (page 395)

From main office to Branch Office using CDP

In this scenario, the following occurs:

DN 3001 or 3002 dials a number "3101".

The main office Call Server recognizes the digits "31" as a CDP DSC.
The Call Server accesses the RLI appropriate for that DSC and uses the
Virtual Trunk specified for that route.

The NRS is queried for a destination node IP address with which to
route the call over the Virtual Trunk. Because "31" is registered to the
Branch Office, the Branch Office node IP address is returned.
