Unicast delivery of media to multiple recipients is achieved. An originating client issues call setup request. A list of addresses of multiple recipient clients is obtained from the call setup request. A connection is then made with the plurality of recipient clients and the media is delivered from the originating client to the plurality of recipient clients. A universal user port agent receives the list of addresses from the originating client and makes the connection with the plurality of recipient clients. When an originating client receives a reply message that a recipient client is unavailable, it may be built with the capability to search for alternate addresses and send a new call setup request.
