Abstract

A system and method for providing group communication services. Each of a plurality of communication devices coverts information signals into data packets suitable for transmission over a data network, such as the Internet. The data packets are transmitted through the data network to a communications manager. The communications manager acts as a configurable switch, allowing communications from any communication device to be routed to the plurality of communication devices. The communications manager further allows users of other communication systems and devices to participate in group communications with each other.
