Hi, since Saturday my Mum's phone has rung at midnight every night. It rings long enough to wake her up but not long enough for her to answer (she is 90 and can't move fast). When she does a 1471 the midnight call is not there, it gives the details of my call the previous afternoon. We have independantly checked 1471 with other calls and that appears to be working correctly on her line.
Has anyone any ideas of the cause or how to stop it?
