Telephony controller with functionality command converter
First Claim
1. A telephony controller for controlling a private automatic branch exchange (PABX) comprising:
- a communication layer for receiving functionality commands from a plurality of command originating computer terminals, said functionality commands conforming to a single functionality command protocol;
a functionality command converter for converting said functionality commands received by said communication layer to PABX commands; and
a PABX interface for transmitting said PABX commands to a PABX and for receiving PABX status information from said PABX, whereby said command originating computer terminals may control and monitor said PABX.

Abstract
A telephony controller for controlling a private automatic branch exchange (PABX) is disclosed that utilizes a single functionality command protocol to reduce the data traffic on a computer network or the like used to control a PABX. The telephony controller includes a functionality command converter, a communication layer for communicating with computer terminals on the computer network, and a PABX interface for communicating with the PABX. The single functionality command protocol uses a generic command format for a number of function commands that are converted by the functionality command converter into the PABX commands corresponding to the vendor specific PABX. The functionality converter generates the PABX commands to implement a function command and monitors the PABX to determine whether the command has been implemented. The functionality command converter generates data messages corresponding to the outcome of the functionality command execution which are transmitted to the command originating terminal. Additionally, the telephony controller is capable of controlling different vendor PABXs without requiring any change in the communication format between the controller and the computer terminals.
