We replaced our UC520 with a new UC540. We are experiencing echo when we are on external calls. It does not matter what line we are on or what phone we are using. The echo is only heard on our side. It is not heard on the phone on the other end. It happens on all external calls. The echo is a static sounding echo.
The problem did not occur on the UC520.
Any one have any ideas?
