Method of routing universal international free telephone phone numbers |
摘要 |
A method of handing off a Universal International Telephone Number to the correct international carrier for handling regardless of which carrier is given the call by the local exchange carrier. If a call destined for termination in the United States is handed off to the wrong international carrier, that carrier routes the call to its international gateway as if it were destined for another country. The international gateway then routes the call to the proper international carrier with all of the routing features and billing schedules of the customer intact.
