Abstract

An adjunct call manager unit connects to a station set port of a telephone communication system and receives button identification and status signals to determine line, agent, and feature activation status of the system. In response to one or more of the received status signals, commands are sent to the system using button depression commands and switchhook commands to effectuate call processing control over the system. In one embodiment, the adjunct unit functions as an automated call distributor for managing incoming calls to the system.
