A method and system for dispatching calls using a packet network is disclosed. The use of distributed call management modules, enables various communication systems, such as RF and PSTN systems, to communicate with each other over the IP network. Audio devices from the various communication systems are each assigned an IP multicast group. Distributed call management modules convert signals from the audio devices into IP packets and transmit the IP packets to designated IP multicast groups over the IP network.
