A communication system comprises a transmitter, a console in operative communication with the transmitter, an audible communication device and a tone simulator. The transmitter is in operative communication with the console and operative to send a first signal to the console. The console is operatively connected to a communication network and is operative to send a second signal over the communication network to at least two response systems. The console comprises a receiver operative to receive the first signal from the transmitter, a controller operative to compare the first signal from the transmitter with a set of pre-determined values, access a communication network and dial one of the at least two pre-programmed voice line addresses, and a communication interface operative to connect the receiver to a communication network. The audible communication device is coupled to the controller and the communication interface. Each pre-programmed voice line address corresponds to one of the two different response systems. The tone simulator generates a first tone upon connection of a voice line communication to one of the two different response systems and a second tone upon termination of audible communication on the voice line between a user of the communication system and an individual at one of the two different response systems. The first tone signals to the console that the voice line communication has begun, and the second tone signals to the console that the voice line communication has ended.
