Well we had pretty good prices on Digium but still the A500 models with EC chip are a bit more expensive for the same port density. I'm however still open to discussion about this of-list :) We still need to integrate these in our stack however. > > But beware that far-end echo cancellation is not Your > responsibility.

We often replace legacy telco PBXs, and of course they "never" had echo before the change . Or so they say. But in the context of a new PBX installation, of course they immediately complain to us.
