Abstract
A computer integrated telephone system that uses the computer's display, internal audio system, or an external interface to indicate that a voice message is waiting. The invention operates with a telephony protocol that supports in-band signaling having Message Waiting ON and Message Waiting OFF messages. The invention is embodied in a PC and includes a telephone interface that interacts with the telephone network to receive Message Waiting ON and Message Waiting OFF messages. In response to the Message Waiting ON message, the telephone interface communicates with software logic on the computer to cause the computer to indicate in an overt manner that a voice message is waiting. In response to the Message Waiting OFF message, the telephone interface communicates with software logic on the computer to cause the computer to turn off the message waiting indicator.
