For a few days now our phone has been ringing just once and then stops and then a few hours later it rings again, mainly it starts around 6pm continuing every few hours throughout the night until late morning 11am and then is quiet most of the day.
On the display it says 'call' whatever that means - with a normal phone call the display is either the number calling or 'withheld' so I don't know what 'call' indicates. Maybe because it only rings once it is too short for the phone to register the originating phone number?
There doesn't seem to be a *69 service (or 1471 in england) here in germany.
It is starting to disturb me altho strangely they don't wait for us to pick up - isn't that usually the thrill part for crank callers? I wonder if it could be computer generated or something.
Any ideas of what can be done?
