Abstract
A method for creating a telephone digital switching platform to provide conversion and routing of telephone calls arriving on a number of telephony interfaces to a number of outbound telephony interfaces, based on in parameter and out of parameter call setup information. Receiving and transmitting interfaces can include, but are not limited to, Integrated Services Digital Network ('ISDN'), Digital Transmission Carrier System ('T-1'), DID ('Direct Inward Dial'), Loop Start, ('E & M') and Direct Outward Dial ('DOD'). Conversion and routing is performed by the steps of capture of call setup information, conversion to 'dial number' via database lookup, selection of outbound pathway based on database information, and placement of outbound call and switched connection to inbound call.
