1. A method for a regional switch to facilitate communication between a first wireless subsystem located in a first geographic area served by a first public switched telephone network (PSTN) access switch and one of a PSTN subscriber located in the first geographic area, a PSTN subscriber located in a second geographic area served by a second PSTN access switch, and a second wireless subsystem located in the second geographic area, the method comprising the steps of:

  • receiving call set-up information from one of the first wireless subsystem, the second wireless subsystem, the PSTN subscriber located in the first geographic area, and the PSTN subscriber located in the second geographic area;

    determining whether the call set-up information indicates a communication between the first wireless subsystem and the PSTN subscriber located in the second geographic area;

    in the event that the call set-up information indicates a communication between the first wireless subsystem and the PSTN subscriber located in the second geographic area, establishing a switching path for the communication, wherein the switching path includes at least a first point of presence (POP) operably coupled between the regional switch and the first wireless subsystem, and at least a second POP operably coupled between the regional switch and the second PSTN access switch;

    determining whether the call set-up information indicates a communication between the first wireless subsystem and the second wireless subsystem; and

    in the event that the call set-up information indicates a communication between the first wireless subsystem and the second wireless subsystem, establishing a switching path for the communication, wherein the switching path includes the at least a second POP and the at least a first POP, but does not include any PSTN access switch.
