I bought the BT8500 back in 2016 and it's been doing a great job of screening our calls up until a few weeks ago , now it lets withheld numbers though to a direct ring rather than going through the announce process , i switched the guardian off and on , went into custom and set withheld to announce this didn't help neither did setting it to block withheld numbers . caller ID seems to be working as other numbers appear on the display. Can anyone offer any advice or help please
Have you tried removing the power to the base unit for about 30 seconds?
Who provides your phone service?
yes tried that , its virgin , but we have been with them for just under a year and never had a problem
If you are now a virgin broadband customer have you tried asking your question on the virgin forum?
It could be an issue with your phone service itself, if the CLI information is corrupted. You need to check with Virgin, as nobody on this BT customer forum would be able to help.
