<p>A method for enabling a first terminal on a packet-based network to communicate with a second terminal accessing a remote access server, comprises the steps of registering the aliases and IP (Internet Protocol) addresses of the first terminal and remote access server into the gatekeeper, letting the first terminal send to the gatekeeper a message for requesting a connection with the second terminal, causing the gatekeeper to request the remote access server to connect with the second terminal even not registered in the gatekeeper, causing the remote access server to request the second terminal to register its alias and IP address in the gatekeeper, and establishing communication between the first and second terminals through the gatekeeper. <IMAGE></p> |
