Abstract

An information processing apparatus for call control and management stores IP addresses of first and second IP telephones and first and second information processing devices associated with the respective IP telephones. When the information processing apparatus receives from the first IP telephone a message requesting to establish a session with the second IP telephone, the information processing apparatus sends, to the second IP telephone using the IP address of the second IP telephone, a message requesting to establish a session with the first IP telephone, to thereby establish a session between the first and second IP telephones. When a session is established between the first and second IP telephones, the information processing apparatus sends the IP address of the second information processing device to the first information processing device using the IP address of the first information processing device and sends the IP address of the first information processing device to the second information processing device using the IP address of the second information processing device.
