Format-converting device and private branch exchange system using the same, and format-converting method and memory medium storing a program to allow computer to execute the same method
A format-converting device couples a control device controlling an extension with a private branch exchange (PBX). A memory stores a converting table, which brings a first command data into correspondence with a given function and stores the first command data and the given function, a telephony application programming interface (TAPI) function and a telephony service provider interface (TSPI) function. A converting section calculates the given function based on the received first command data referring to the converting table. A first calculating section calculates the TAPI function. A second calculating section calculates the TSPI function. The first calculating section calculates based on a calculated result of the converting section. The second calculating section produces a second command data based on a calculated result of the first calculating section, where the second command data differs from the first command data. The second command data is sent to the PBX.
