Patent ID: 6862626

Claim:
A method for enabling a first terminal of a packet-based network to communicate with a second terminal accessible by a remote access server, comprising the steps of: (a) registering the aliases and IP addresses of said first terminal and said remote access server in a gatekeeper connected to said packet-based network; (b) transmitting from said first terminal to said gatekeeper a message for requesting a connection with said second terminal; (c) causing said gatekeeper to request said remote access server to connect with said second terminal even when said second terminal is not registered in said gate keeper; (d) when the remote access server point-to-point connects, and assigns an IP address, to said second terminal by calling said second terminal over a circuit network, causing said second terminal to register the alias and the IP address of said second terminal in said gatekeeper; and, (e) establishing communication between said first terminal and said second terminal via said gatekeeper.
