Flash Key
You can set a programmable key or expansion module key to generate a flash event when it is 
pressed on the 6753i. You do this by setting the key to "flash". The IP phone generates flash events 
only when a call is connected and there is an active RTP stream (for example, when the call is not 
on hold).
