Abstract

Systems and methods provide foreign call back number compatibility. The systems and methods receive a local telephone number assigned to a subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber. Furthermore, the systems and methods query a database with the local telephone number to obtain the non-local telephone number and to provide the non-local telephone number. In addition, systems and methods provide a foreign call back number compatibility database. The systems and methods receive a local telephone number assigned to a subscriber and a non-local telephone number comprising the normal calling number of the subscriber and saving the local number and the non-local number to a database.
