Enabling/Disabling Voice Activated Phone Answering (Default: Enable)
If this feature is enabled, you can answer incoming calls by voice. When you hear a ringtone for an incoming call, you can answer the phone by saying a word such as “Hello” loudly or by blowing air into the microphone. VOX phone is temporarily disabled if you are connected to intercom. If this feature is disabled, you have to tap the Center Button to answer an incoming call.
You can change this setting in the configuration menu.
