I purchased a pair of BT6500 about 4 months ago and it has been brilliant for screening out nuisance calls, witheld calls and international calls etc but for the last 2 days whenever anyone rings the screen says "no number" instead of showing who's calling. I definitly have caller ID on my phone and it has always worked fine. This has got so annoying and I have answered a couple of numbers which I know should be blocked but they are now getting through. Nothing has changed on the settings, no one has been messing around with the phones, I am now finding this increasinly frustrating. Can anyone shed any light on this please. I would be really greatful. Thanks
My caller display stopped working after I changed my Answer Machine settings to use "Time Saver" on both "Ans. & record" and "Answer only" modes. I only realised that the problem must have coincided with the changes after a few days. Resetting both modes to a 4 ring delay got caller display working again. Software problem? I only recently purchased my phones and the software versions are Handset: XH08322_H5125, Base: XB0810_B5124.
