Starting in January 2024, the domestic fixed telephone network is scheduled to switch from the traditional communication network to an IP network. The background for this change includes a decrease in the number of landline subscriptions due to the diversification of communication methods, as well as the fact that telephone exchange equipment is expected to reach its maintenance limit around 2025. Until now, we have been using PSTN connections specialized for voice, but with IP connections, it will be possible to provide internet, voice, and video services all through the same line. Therefore, after the switch to the IP network, it is expected that various services will begin to be offered, and further proliferation of optical lines and high-speed mobile communication is anticipated. SIP SIP GW (SIP SIP Gateway) is a gateway device that enables connection to the IP network.
