Telephony 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.
