Abstract

Abstract An arrangement is disclosed as an applique to a PBX to allow a PBX attendant to originate a series of message delivery calls. The attendant dials in PBX station numbers to which the message is to be delivered. These numbers are temporarily stored in a memory and sequentially outpulsed to the PBX in the order in which they were dialed by the attendant. The PBX then establishes a connection from the arrangement to a station identified by an outpulsed number. When the party at that station answers, a recorded message is connected to the established connection. After the message is delivered, the next station number in the memory is outpulsed to the PBX. Circuitry is provided to notify the PBX attendant when there is a failure to complete call if there is no answer or if the called station is busy.
