<P><FONT SIZE=2 FACE="Arial">Hi,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I have 2 users complaining of feedback / Echo on 2 Cisco 7940 phones.</FONT>
<BR><FONT SIZE=2 FACE="Arial">The phones are connected to a Cisco Catalyst 3524XL-PWR switch, along with 20 other 7940's.</FONT>
<BR><FONT SIZE=2 FACE="Arial">No other users on this switch are experiencing any issues.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I have replaced one of the phones, but the issue is still there.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">The switch is running IOS ver c3500xl-c3h2s-mz.120-5.WC03, I noticed the latest version is c3500xl-c3h2s-mz.120-5.WC14 which I can only upgrade to out of hours.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Is there anything else I can check to resolve this issue?</FONT>
<BR><FONT SIZE=2 FACE="Arial">Switch Config is pasted below:</FONT>

<P><FONT SIZE=2 FACE="Arial">Thanks</FONT>
