Remarks

These constants are used both in LINEADDRESSCAPS (returned by lineGetAddressCaps) and in LINECALLSTATUS (returned by lineGetCallStatus). LINEADDRESSCAPS reports the availability of the call features on the specified address. An application would use this information when it initializes to determine what it may be able to do later when calls exist. For the specified call, LINECALLSTATUS reports which call features can be invoked while the call is in the current call state. The latter takes call privileges into account. An application would make this determination dynamically, after call state changes.

The LINECALLFEATURE_RELEASEUSERUSERINFO value is new to TAPI 1.4. There are no backward compatibility considerations. A service provider may elect to return this value in relevant members (in LINEADDRESSCAPS and LINECALLSTATUS) even when older API versions have been negotiated on the line device.
