Conference calls
You can set up a three-party call by using two 
lines at the same time. You can also join an 
intercom call with a call on an outside line. The 
outside line call must be established first, because 
an intercom call cannot be placed on hold.
1.  Make or answer an outside call.
2.  Press and release 
[HOLD].
3.  Call someone on another line, or intercom    
  someone.
4.  When this call is answered, press      
  [CONFERENCE]. The three-party conference  
  begins immediately.
To talk privately with one party (two-line 
conference only):
1.  Press 
[HOLD] to place both lines on hold.
2.  Press a 
LINE button to talk privately with the  
  person on that line.
3.  Press 
[CONFERENCE] to resume the    
  conference call. 
To drop one line:
Press the LINE button for the party you want to 
keep. The other line is dropped.
To drop an extension:
Press the LINE button twice. The other system 
extension hangs up.
To end a two-line conference call, hang up. All 
parties disconnect.
To end a two-extension conference call, hang up 
on both system extensions. All parties disconnect.
