The TAPI (Telephony Application Programming Interface) 3.0 component is a COM-based API that merges normal telephony with IP telephony. This component enables a developer to implement COM-based communications applications that range from simple voice calls over Public Switched Telephone Network (PSTN) to multicast, multimedia IP conferencing with quality of service (QOS).
Use TAPI 2.2 to support C-based communications applications.
There are no configuration requirements for this component.
