A version of this page is also available for

The Telephony API implementation is a subset of the Microsoft Telephony Application Programming Interface (TAPI) version 2.0 and some parts of TAPI version 2.1. TAPI provides an application programming interface (API) that simplifies and abstracts the details of making telephony connections between two or more devices. TAPI abstracts call-control functionality to allow different, and seemingly incompatible, communication protocols to expose a common interface to applications through its support of telephony service providers (TSPs).
For Windows Mobile devices, attempting to make cellular connections directly through TAPI is not supported Cellular connections should be made through Connection Manager.
