Telephony consists of a number of standard APIs used to handle telephony connections between devices. TAPI (Telephony API), Extended TAPI (ExTAPI), Telephony Service Provider (TSP) and Assisted TAPI are exposed by telephony specific components in CellCore.
TAPI is based on a subset of TAPI 2.0 features such as Call Waiting, Call Forwarding and Dialing. ExTAPI is architecturally identical to TAPI and it extends the API set to include wireless related features such as Call Barring, HSCSD options and Operator Selection. ExTAPI calls are implemented using the lineDevSpecificTAPI function. TAPI uses the TSP interface (TSPI) to control the underlying TSPs.
Assisted TAPI is a useful component for voice calls, and it implements the tapiRequestMakeCall. This component is useful since it is otherwise a complicated operation to establish a simple voice call.
