</div></div> Check "dmesg" on your system for messages like:<br>
<br>
VPM400: Support Enabled/Disabled<br>
VPM450: Support Enabled/Disabled<br>
<br>
That should tell you if the hardware echo cancellation is working or<br>
not. The TE410P does not have hardware echo cancellation the model was<br>
TE411P. If you can open the server you should be able to see if the<br>
card has a daughter board installed which is the echo module.<br>
