Setting a "Flash Key"
You can set a programmable key to generate a flash event when it is
pressed on the 53i. You do this by setting the programmable 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).
