System and method for providing automatic determination of a call type in telephony services over a data network

Abstract

A system and method for providing automatic determination of a call type in a voice over Internet Protocol data network is provided. A 10-digit telephone number for making a telephone call is entered and a look up of the telephone number is performed in a database comprising at least known long distance numbers. If no match exists, the telephone number is transmitted over the data network to a local Call Management Server. If the local call is not successful, the number is automatically transmitted with a pre-pended “I” to a Long Distance Call Management Server. Advantageously, a VoIP system is provided for automatically determining that a number is a long distance call, upon which it will automatically pre-pend a leading “1” to the number and re-transmit the resultant 11 digit number to the appropriate Long Distance Call Management Server.
