A real time communication device operates on with a packet switched network. The packet switched network interconnects the real time communication device with a control unit and at least one other real time communication device. The real time communication device includes a plurality of indicators with each indicator being uniquely associated with one of the other real time communication devices or with an outside line between the control unit and a central office of a local telephone service provider. A selection means is associated with each indicator. The real time communication device may establish a logical channel over the packet switched local area network with an endpoint. The endpoint is selected from the group of endpoints consisting of the control unit and the other real time communication devices and is the endpoint that is uniquely associated with an indicator selected from the plurality of indicators. The logical channel is established in response to operator activation of the selection means associated with the indicator.
