Abstract
A radio communication controller (106, 401) is disclosed which is capable of accessing a database having a subscriber unit identification code (302, 601) and a preselected calling code, or area code, accumulating a keyed Public Switched Telephone Network (PSTN) telephone number from the subscriber unit wishing to make an interconnect call (110, 407), and comparing (215, 518) this area code with that of the controller site. The controller, as employed by the invention, is further capable of deciding whether or not the area code is required for completing the interconnect call, and if so, prefacing (217, 520) the accumulated PSTN telephone number with the area code preselected by the user of that subscriber unit.
