Abstract:
1. A system comprising: an information processing apparatus that controls and manage a call between devices; a first IP telephone that comprises at least one of a contactless information storage device and a contactless reader/writer device; a first information processing device that is configured to be operated by an end user and operable independently of an IP telephone, and comprises at least one of a contactless reader/writer device and a contactless information storage device; a second IP telephone; and a second information processing device that is configured to be operated by an end user and operable independently of an IP telephone, wherein the information processing apparatus the first IP telephone, the first information processing device, the second IP telephone, and the second information processing device are connectable to an IP network, wherein the information processing apparatus stores, as registration information, a first telephone identification and a first IP address of the first IP telephone, a first device identification and a second IP address of the first information processing device associated with the first IP telephone by a first association identification that is read by the contactless reader/writer device of the first information processing device or the first IP telephone from the contactless information storage device of the first IP telephone or the first information processing device, a second telephone identification and a third IP address of the second IP telephone, and a second device identification and a fourth IP address of the second information processing device associated with the second IP telephone, and in response to a request for establishment of a session received from the first IP telephone or the first information processing device, the information processing apparatus sends a request for establishment of a session between the first IP telephone and the second IP telephone, to the first IP address and the third IP address stored as the registration information, to establish a session between the first IP telephone and the second IP telephone, and notifies, in accordance with the registration information, one of the second IP address and the fourth IP address of corresponding one of the first and second information processing devices to the other information processing device at the IP address thereof, to dynamically establish a peer-to-peer session between the first information processing device and the second information processing device while the session between the first IP telephone and the second IP telephone is established or continues.
