Line Keys and Programmable Keys

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).
