I have noticed a loud scratchy noise on 2 or 3 of our customers UC5XX systems.
Has anyone else experienced this? Is there a solution?

Some addtional delails are needed like
Exact phone type and firmware
Type of lines used
Country where installed
Voice port configuration
Does it happens anytime or on some calls only ?

All spa504g - fw 7.5.2b.
Isdn - BRI.
It's a distorted scratchy noise ( I have a .wav but can't attatch )
Installed in the UK.
It happens on ALL phones, but not every call.

Please send voice port config as asked before, as well "show network-clocks"
You should also update phone fw to 7.5.3 and check again.
