Why does the X100P have echo and the Wildcard TDM400P have no echo?
I thought the only advantage of using the TDM400P was that it used less
interrupts than the X100P?
Are there any other advantages?
Cheers,
Dean

Thanks for the tip. However, I have been trying evening after avening to
get the echo out by tweaking the settings. When I received the TDM11 I
pulled out the X101P clone followed the example config at the Digium
site
and I was up and running without any. I don't mind trying to play around
but wasting a lot of time on really cheap hardware was too much waste of
time when I look back :)
It's probably possible to get the echo out but it's not worth it for me
to
figure it out :)
