Abstract

See full text

A telecommunications system utilizes a central database to determine characteristics for international calls, to facilitate call routing for international calls, or both. The central database includes termination information for telephone numbers in multiple nations outside the North American Numbering Plan. In one aspect, an interexchange switch receives a termination number for an international call from a local exchange carrier and uses information from the central database to help complete the call. In another aspect, the central database receives a telephone number from a remote user such as interexchange carrier (IXC) and, in response, transmits termination information to the remote user to identify whether the telephone number uses wireless termination. The remote user may then charge a customer for wireless termination, if appropriate, possibly even before the remote user receives an invoice that reflects wireless termination charges from a foreign wireless carrier.
