do this give any benefit of echo cancellation? Our PSTN gateway is a separate
Audiocodes box, so the zaptel card wouldn't actually be connected to anything.
I'm wondering though doing this would help, in general, with echo cancellation.

I wouldn't think so, since the echo cancellation settings are in zaptel-land. So 
the call path would have to go through a zap channel before the echo canceller 
can work.
