Abstract

A call processor (32) for intercepting incoming calls to a key telephone system (10) and returning a message to a calling party. A digital message storage unit (48) stores messages associating called parties with respective pseudo-telephone numbers so the calling party can input information identifying a desired called party. A CPU (50) of the call processor (32) references a look-up table (52) with the pseudo-telephone number input by the calling party to select and transmit a message via an intercom line (36) to the key telephone system (10). The message carried by the intercom line (36) broadcasts a message relating to the identity of the called party as well as the line to utilize.
