  • Telephone travel card system under the control of its customers
    Publication number: 20020061093
    Abstract: A telephone system for travel card users where the users may program a switch processor so that it completes, re-routes, or refuses to complete calls as predetermined by the customer. Data is captured as it is transferred from the switching module to an internal buffer and is fed through a digital communications path and an analog-to-digital and digital-to-analog converter to a switching station computer. The switching station computer is in communication with a data storage server computer and the data storage server computer is in communication with remote telephones and with computers and facsimile machines in remote customers' offices. The switching station computer is thus programmable by the customer and incoming calls are handled as predetermined by the customer. A voice response device provides verbal communication between the system and its users.
