Mine gives me "comfort noise" when the line is silent, which may be
what you're referring to.  See if it goes away when you say something
into the "dead air", and see if it returns a moment after you stop
speaking to yourself.  I can hear a slight sound, but it's not what
I'd call loud.

I prefer to have the comfort noise than not, but if it was loud and
persisted over the top of a conversation then that'd be bad.  It doesn't
do that for me.

There may be an admin setting for the comfort noise level, or noise
on/off, although I don't recall seeing it.
