A system for establishing an Internet Protocol (IP) connection with a
terminating node includes an originating node capable of initiating
communication with the terminating node. The system also includes an
intermediate node located between the originating node and the
terminating node. The originating node is capable of initiating
communication by either (a) requesting communication with the terminating
node via the intermediate node, or (b) notifying the terminating node of
incoming data independent of the intermediate node. In this regard, when
the originating node initiates communication in accordance with (a),
either the originating node or the intermediate node is capable of
notifying the terminating node of incoming data. Upon being notified of
incoming data, then, the terminating node is capable of registering with
the intermediate node to thereby establish an IP connection between the
originating node and the terminating node via the intermediate node.
