Abstract
A method and system for integrating a computer and a telephone. A stimulus messaging device, such as an analog telephone, is provisioned as a functional messaging device, such as an ISDN telephone, at a switch. The switch communicates with the telephone through a loop interface device. The loop interface device translates ISDN messages destined for the telephone received from the switch into analog signals for the telephone. The loop interface device also sends the ISDN messages received from the switch to a computer associated with the telephone. The loop interface device translates analog signals received from the telephone into ISDN messages for transmission to either the switch and/or the computer. The present invention enhances call control information for an analog telephone and allows tight integration between a telephone and a computer.
