Phonebook Examples
North America
The following example demonstrates how Outbound and Inbound Phonebook entries work in a situation of
multiple area codes. Consider a company with offices in Minneapolis and Baltimore.
Notice first the area code situation in those two cities: Minneapolis's local calling area consists of multiple
adjacent area codes; Baltimore's local calling area consists of a base area code plus an overlay area code.
An outline of the equipment setup in both offices is shown below.
