Latest Patents

Two of Ebisawa’s latest listed patents concern telephone-system architecture and control.

“Telephone System and Server Apparatus and Control Method Used in Telephone System” describes a system with telephone terminals and server apparatuses. One server authenticates a terminal’s license by comparing its terminal ID with information stored in a license memory. It then retrieves the corresponding license authentication code and sends it to the terminal with check information.

“Telephone System, Telephone Exchange Apparatus, and Connection Control Method Used in Telephone Exchange Apparatus” addresses media distribution and call connections. The exchange apparatus maintains a table linking terminal IDs, server IDs, and codec information. Using that information, it can identify terminals with calls using the same codec and dynamically connect them to a media server through a distribution server.
