So my BT6500 was a bit of a problem when I first set it up and ordered caller display, BT sorted it as all mobiles were going to answerphone. So all has been fine for month or so but this week all 01 and 02 numbers are coming up as international, I've had my line checked and it is fine so im stuck really, what I have done is add the people who call me that go to international as contacts and that works.
It really appears to me that BT haven't really tested this phone properly as the number of complaints on here about these phones is ever growing !!!
