We regularly experience calls being dropped e.g. one interruption in a call tonight, several interruptions to a call on Sunday evening. Can happen with different numbers and incoming or outgoing. My wife uses the phone more than I do and is getting very annoyed!
Welcome to the Community, I'm very sorry to learn about the problems you're experiencing with your telephone line recently.
I've been able to locate your account and run some tests on the line from our end for you. We're not seeing any issues from our end at the moment though, have you been able to test your handset? By trying an alternate handset or your handset on an alternate line?
