My single Philips Voip phone I use under Windows, and which compliments my other a land line phones at other times, lately has taken to waking up the family on the odd night by playing a melody and with the display lit up the message "paging" is displayed ???
The only way to prevent this unusual behavior is for me to remove the batteries at night.
Can anyone offer an plausible explanation for this strange thing to happen?

The batteries are fully charged and above the correct voltage.
