System and method for establishing an Internet Protocol connection with a terminating network node

A method comprising:

• receiving a notification of incoming data at a terminating node from an originating node or an intermediate node located between the originating node and the terminating node;
• and
• registering the terminating node with the intermediate node in response to receiving the notification at the terminating node to thereby enable Internet Protocol (IP) communication between the originating node and the terminating node via the intermediate node.

An apparatus comprising:

• a controller configured to receive a notification of incoming data from an originating node or an intermediate node located between the originating node and apparatus, wherein the controller is also configured to register the apparatus with the intermediate node in response to receiving the notification to thereby enable Internet Protocol (IP) communication between the originating node and the apparatus via the intermediate node.

A system comprising:

• a network address translator (NAT) located between an originating node and a terminating node, wherein the NAT is configured to receive a communication request from a network node, and in response to the connection request, notify the terminating node of incoming data to thereby enable the terminating node to register with an intermediate node located between the originating node and the NAT to thereby enable Internet Protocol (IP) communication between the originating node and the terminating node via the intermediate node.

An apparatus comprising;

• a receiving means for receiving a notification of incoming data from an originating node or an intermediate node located between the originating node and the apparatus;
• and
• a registering means for registering the apparatus with the intermediate node in response to the receiving means receiving the notification to thereby enable Internet Protocol (IP) communication between the originating node and the apparatus via the intermediate node.
