2.4.1.15 Call Handle Manipulation

The API provides a number of functions for manipulating call handles, determining the relationship between lines, calls, address, etc. Most of this functionality is implemented strictly within the TAPI DLL without reference to the Service Provider, except for TSPI_lineGetCallAddressID. This procedure retrieves the address ID of an existing call within its line. Service Providers that model a line as a group of address IDs may choose an unpredictable address for a new inbound or outbound call. This function gives the TAPI DLL sufficient information to implement the lineGetCalls operation when it is invoked with the LINECALLSELECT_ADDRESS option.

TSPI_lineGetCallAddressID

Retrieves the address ID of an existing call within its line.
