I think that if I could go back and do this project over, I would have
chosen DECT as well. We have intermittent problems with the wifi AP's
also.

I have not really messed with the QoS on my network, I guess that will
be my next step. I am running 1 - 3Com Unified Gigabit Wired and

Switches. I know these switches support VoIP. I guess I'll

I have not tried it without any echo cancel. I'll have to try that.
Thank you. I'm not sure about rx and tx gain. I adjusted the values and
it seemed to make a difference.

Someone has to have had some experience with these hardware echo
cancellers, any ideas? Should I adjust my rx and tx gains? Any advice
would be very helpful. Thank you.

Interesting. I will give that a try.
Also, any idea between the difference in switchtype between national
and 4ess? All the documentation I read labeled 4ess as ATT, but I
didn't try the national to see if it changed anything, like echo or
signal quality.

What would be the best solution to
remove echo?

It is showing MG2 as the echo canceller, even though I don't have an
echo canceller specified. Is that the harwdare module? Do I even need
to specify an echo canceller in the configs if I have a hardware echo
module?
