Buzzing on calls

[JanetJC]

There is a buzzing on my landline on every call, heard by me and the person I'm speaking with, which quickly gets louder as the call progresses. It's been going on for weeks and is very annoying! Thank you.

Good morning,

I'm sorry to hear this. I've run a few tests on the line now and they have detected a loop fault which can sometimes be caused by internal wiring or equipment connected to the line. Does your main socket have a test socket please?

Thanks

Michelle
