I have a BT 4500 dual handset and my phone contract is with BT including Caller Display. I used to be able to view the calls list on both handsets but now I can only view it on one of them. The other handset says "Not available". Anyone know why?
Thanks for the suggestion. It's working OK since I went to Reset in Settings. Not sure how, because I exited out of the menus without selecting Reset, but it said it was synchronising and that seemed to do the trick.
