Switch back and forth between two callers 
After using the call waiting option to answer a second incoming call, pressing the Flash key allows 
you to switch back and forth between caller B and C by putting either one on hold. 
Hang-up your current call before answering an incoming 
call 
Step 1.  You are currently on an active call between A and B. 
Step 2.  You hear an indicator tone signaling an incoming call C. 
Step 3.  Simply hanging-up will terminate the call between A and B. 
Step 4.  Wait for the phone to ring. 
Step 5.  Answering the incoming call will start an active call between A and C. 
Disconnect the second call and switch back to the first call 
While caller B is on hold, simply hang-up the phone set to disconnect caller C. Then wait for the 
phone to ring, and pick-up to return to the active call with caller B.
