Abstract: A telephone switching device (10) according to the present disclosure includes a storage unit (11) that stores a registration table (11a) registering a plurality of personal telephone numbers for each telephone terminal, an acquisition unit (12) that acquires an authentication result of a user with respect to the telephone terminal, a registration unit (13) that registers the telephone terminal and a personal telephone number of the user in the registration table (11a) in association with each other, according to the acquired authentication result, and a control unit (14) that controls incoming/outgoing calls using the personal telephone number of the user in the telephone terminal, based on the registered registration table (11a).

Abstract: There is disclosed a private branch exchange in which an SIP terminal is capable of receiving great variety of services provided by the private branch exchange without upgrading version of software of the SIP terminal itself. A standard SIP protocol control module 16, an expanded SIP protocol a control module 17, and an expanded SIP protocol b control module 18 are disposed for SIP system protocol corresponding terminals, convert signals (requests) from the SIP system protocol corresponding terminals into signals of a protocol inside an IP-PBX 1 to transmit the signals to a PBX basic connection process providing module 12, and convert a signal (responses to the request, or a request to the SIP system protocol corresponding terminal) from the PBX basic connection process providing module 12 into a signal of an SIP system protocol to transmit the signal to the SIP system protocol corresponding terminal.

Abstract: A standard-SIP (session initiation protocol) protocol control module and an expanded sip protocol control module are provided so as to correspond to respective Sip protocol corresponding terminals, such as wireless LAN terminals compliant with the SIP. A signal (a request) from each Sip protocol corresponding terminal is converted into a signal according to a protocol of an IP-PBX and is sent to a PBX basic-connection-processing providing module. A signal (a response for the request or a request to the Sip protocol corresponding terminal) from the PBX basic-connection-processing providing module is converted into an Sip protocol signal and is sent to the Sip protocol corresponding terminal. A location-information management module collects a basic service set identifier (BSSID) from each wireless LAN network and stores the BSSID information into a database.
