Call quality on iPhone 6s. on OS 14.3

Call quality on my iPhone 6s has suddenly deteriorated

its unusable on most ( but not all ) calls

Im calling from the same place and on the same network as previously- it’s worked fine for about 2 years.

I have good signal strength and am sat in my office. So not moving around.

I have checked the microphone and that’s working fine.

I am on os 14.3 I was wondering if an OS upgrade caused it ?

Does anyone has the same issue and solution

iPhone 6s, iOS 14
