Go to the configuration menu to disable this feature. VOX phone is enabled by default.
Tap the (+) Button or the (-) Button until you hear the voice prompt, “VOX phone”. If this feature is enabled, you can answer incoming calls by simply saying a word loudly enough, unless you are
connected to intercom. For example, when you hear a series of beeps for an incoming call, you can answer the phone by saying “Hello” or any other word loudly. However, the phone VOX feature
does not work if you are connected to intercom. This is enabled from the factory but you can disable it. If this mode is disabled, you have to tap the Center Button to answer an incoming call.
