I have had decreased quality on Skype calls for the past few weeks. My internet is fine otherwise. I have ensured both users have the same version. We are not using web cams. I have run speedtests and everything seems fine. Online gaming runs with no issues. But the calls fading in and out of sound and theres a white noise constantly of late too, not headset related as it happens in other calls and Discord appears to be fine. Does anyone have any ideas?

I am a Sky Fibre Unlimited user.
