<body class='hmmessage'><div dir='ltr'>Hi All,<BR> <BR>Has anyone come across a high pitched noise coming from a Cisco 8941. Sample noise attached. These are contact centre agents and this noise happens intermittently, internal, external and apparently IP to IP. They do have other phones in the office 6921's but no issues from these phones.<BR> <BR>They are running firmware 8945.9-3-2SR1-2.<BR> <BR>Any ideas?<BR> <BR>Kind Regards<BR> <BR>Cos<BR> <BR> <BR> </div></body>
