Abstract
In a communications system where a plurality of endpoints share a virtual address, all of the endpoints are involved in a communication with one of them, but only one has its talk path enabled at any one time. Each endpoint has an actuator that, when actuated, enables that endpoint's talk path and disables the other endpoints' talk paths. Preferably, one of the endpoints is either an announcement facility or a teletypewriter, while another one of the endpoints is a telephone.
