Abstract
Prior to communication over the Internet and using a different line, a first terminal transmits to a second terminal a set of information including at least an IP address of the first terminal on the Internet. Based on the IP address thus transmitted separately, the party at the second terminal initiates communication over the Internet. This establishes direct end-to-end communication between the two terminals over the Internet. In a communication setup such as an Internet-based telephone call wherein address information about a desired party on the network is not previously known to a calling party, the inventive method allows the two parties to communicate directly with each other over the network on an end-to-end communication basis without recourse to a rendezvous server or like services.
