The following table shows the LINECALLFEATURE constants.

LINECALLFEATURE_REMOVEFROMCONF = 0x00040000	Remove the call from the conference (lineRemoveFromConference).
LINECALLFEATURE_SENDUSERUSER = 0x00100000	Send user-user information (lineSendUserUserInfo).

Remarks

These constants cannot be extended. All 32 bits are reserved.

These constants are used both in the LINEADDRESSCAPS (returned by lineGetAddressCaps) and in the LINECALLSTATUS (returned by lineGetCallStatus) structures. 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.
