The LINEANSWERMODE_ bit-flag constants describe how an existing active call on a line device is affected by answering another offering call on the same line.
Not extensible. All 32 bits are reserved.
If a call comes in (is offered) at the time another call is already active, the new call is connected to by invoking TSPI_lineAnswer. The effect this has on the existing active call depends on the line's device capabilities. The first call may be unaffected, automatically dropped, or automatically placed on hold.
