Thank you for the reply.
I was expecting a PM for account details, as in the other posts, so full marks for finding those details out as you have. 👍
I cannot use another phone. This is a 3 phone cordless set. The only other phone I have is a corded phone for powercuts, and that has no screen on it. 🙁
I could switch off Call Guardian, but would then be exposed to all the callers it blocks.
BT do not do too much well, but Call Guardian is one of the successes, it is brilliant at what it does.😁
It appears to be working again now, so I will monitor and try and see if I can see some pattern to it.
