ABSTRACT:
Systems and methods for enforcing calling restrictions are provided. When a first and second communication station are located in different domains, calling restrictions for a first communication station can be based on a current geographic location of the second communication station. The calling restrictions can be enforced independent of an address/identifier of the first or second communication station. The calling restrictions can be based on the current geographic locations of the first and second communication stations and the allowed geographic area of the first communication station.
