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.
