The LINECALLFEATURE_ constants list the operations that can be invoked on a call using this API.
Not extensible. All 32 bits are reserved.
These constants are used both in LINEADDRESSCAPS (returned by TSPI_lineGetAddressCaps) and in LINECALLSTATUS (returned by TSPI_lineGetCallStatus). LINEADDRESSCAPS reports the general availability of the call features on the specified address. An application can use this information when it initializes in order to determine what it can do later when calls actually do exist. LINECALLSTATUS reports for the specified call the call features that can actually be invoked while the call is in the current call state. The latter takes call privileges into account. An application makes this determination dynamically, after call state changes.
