Zusammenfassung:	A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 . Upon a first communication unit ( 213 ) initiating a call request for a 2-party call with a second communication unit ( 215 ), a call server 235 identifies respective multicast IP addresses (MC 1 , MC 2 ) associated with the source and target. If the first communication unit 213 , or its associated site ( 205 ) desires to send payload to the second communication unit 215 , it addresses the payload to the multicast IP address (MC 2 ) of the second communication unit, and the second communication unit 215 , or its associated site 206 joins the multicast address MC 2 to receive the payload. Conversely, if the second communication unit 215 , or its associated site ( 206 ) desires to send payload to the first communication unit 213 , it addresses the payload to the multicast IP address (MC 1 ) of the first communication unit, and the first communication unit 213 , or its associated site 205 joins the multicast address MC 1 to receive the payload.
