Voice dialling
When no call is in progress, press and hold the answer/end key until you hear a
tone that indicates that you can say the desired name ("voice tag"). Say the voice
tag. The phone plays the voice tag and dials the related phone number.
You can also activate voice dialling with the phone. For details on voice dialling,
see the phone’s user’s guide. Note that this function is only available if the phone
supports voice dialling.
