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