Have you seen the troubleshooting guides on <a href="http://cisco.com">cisco.com</a>
regarding echo? <br>
<a
href="http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a0080149a1f.shtml">http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a0080149a1f.shtml</a><br>
<br>
The echo is probably less to do with your CUCM and IP Phones and more to do
with the gateway and the outside telephone systems your people are calling.<br>
