Telephony service provider

This article is about the Microsoft API for telephony. For Internet PSTN gateway and VoIP companies, see Internet telephony service provider.

Not to be confused with Telecommunications service provider.

A telephony service provider, as defined in Microsoft's TAPI specification, is a software interface to a physical telephony device (such as a modem) that can be accessed programmatically to perform actions such as dialing a phone number or logging a call. TSPs can be thought of as a TAPI specific driver for a telephony device.
