184 Planning and management
•All other long-distance numbers have other routingas appropr iate
(1-NPA-NXX-XXXX).
At the Branch Office, the following items must be configured:
•Long-distance numbers in the same area code, such as 1-506-234-1234
or 1-506-675-1234.
•Long-distance numbers at the main office are configured to go over
the Virtual Trunk and use PSTN trunks at the main office, such as
1-613-967-1111 or 1-613-555-1212.
•All other long-distance numbers have other routingas appropr iate
(1-NPA-NXX-XXXX),but most are routed through the main office.
If a main office telephone goes off-hook and dials "9 555-1212," the Call
Server assumes the user intends to reach the number 555-1212 in the local
NPA.The fully-qualified number (E.164) is 1-613-555-1212.
If an MG 1000B IP Phone goes off hook and dials "9 555-1212," the MG
1000B Call Server assumes that the user intends to reach the number
555-1212 in the NPAthat is local to the Branch Office, and thus the fully
qualified number (E.164) is 1-506-555-1212.
Since the main office must reach the MG 1000B PSTN resources (through
the MG 1000B Core), the call is treated like a PSTN toll-avoidance call.
(This is a private-network-routed call with public network termination.)
For other examples, such as calls between different NPAswithin the same
city,refer to the "Dialing plan configuration" (page 291).

zone characteristics in LD 117 at the main office. For example, assuming
