primary.
Ringing primary: When the primary line is set to Line 
and Line  is ringing, Line  is automatically connected.
Ringing non-primary: When the primary line is set to
Line  and Line  is idle while Line 2 is ringing, Line 2 is
automatically connected.
Idle primary: When the primary line is set to Line  and
both lines are idle, Line  is automatically connected.
Idle non-primary: When the primary line is set to
Line  and Line  is busy while Line 2 is idle, Line 2 is
automatically connected.
Busy primary: When the primary line is set to Line 
and Line  and Line 2 are busy, Line  is automatically
connected.
NOTE: The same logic applies if the primary line is set to Line 2.
