Telephony service provider
A telephony service provider, as defined in Microsoft's TAPI specification, is a software interface to a physical telephony device 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.
For example Windows 10 supplies:
- hidphone.tsp
- kmddsp.tsp
- remotesp.tsp
- unimdm.tsp
