Loud Noise On Inbound And Outbound Calls

          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.

To attach files, click "use advanced editor".
