TAPI The telephony applications programming interface (TAPI) system-board connector uses a 4-pin cable to interface your internal TAPI-compliant expansion card with the audio system in your computer. To locate the TAPI system-board connector, see "System Board Components." Your computer supports TAPI-compliant cards using the standard TAPI connector (labeled TELE). For example, you can connect your modem to the TAPI connector and then use your audio speakers and microphone as a speakerphone. The microphone carries your voice into the computer and then through the TAPI system board connector to your modem card. The caller's voice enters through the modem card to the TAPI system board connector and then out to the speakers. You can also use this configuration to record and play sound files over the phone.
