Telephony Application Programming Interface (TAPI) receives requests from applications and forwards them to telephony devices such as modems, telephones, Integrated Services Digital Network (ISDN) equipment, or Private Branch Exchanges (PBXs).

TAPI manages such functions as

  • Signal
  • Hold and transfer
  • Conference and call park
  • Other PBX functions

TAPI location

If you travel frequently and use a laptop, create a TAPI location for each geographical site that you commonly visit. A TAPI location is a set of information used by dial-up networking that specifies a country, area code, dial-out information, and calling card information. TAPI-aware applications such as dial-up networking use TAPI locations to correctly dial from a given location.
