That's a good idea.  I hadn't thought of using a crossover cable and a
dedicated card like that.  (Though, that said, I suspect that the
datapath through our regular network switches is probably close enough
to lossless for this purpose as well.)

Any recommendations as to which ATAs are suitable for this purpose?  I
don't remember seeing a way to disable echo cancellation on either the
Grandstream or the Sipura ones that I have here.
