International ClassesH04M 001/64H04M 011/100 AbstractThis invention relates to a method and apparatus for establishing telecommunications calls. An intelligent peripheral is bridged to a call being dialed. If the intelligent peripheral recognizes a need to supply information for establishing a call, or for signaling a customer request, the intelligent peripheral supplies digits or characters on the customer's behalf for use by the switch. The peripheral optionally has speech recognition apparatus for interpreting customer requests and supplying the digits needed to implement that request.Other References
