What is the reason you need a separate hardware echo-canceling system? We have an Asterisk system with 3 fully echo-cancelled T1s doing 60,000+ calls per day with no problem with echo.
What kind of echo are you getting on your Asterisk server right now and what are your Zapata echo settings? One thing to keep in mind is that Digium will be releasing a quad T1 card with hardware echo-canceller on-board in the next couple months, and Sangoma is going to release their own hardware echo-canceller on-board Quad T1 card before the end of the year as well.

Is that the 253B shelf? Wire-wrap is not really the problem. The real problem is availability (though size is also a consideration). I just looked through the Tellabs equipment on ebay and don't see any of the 8-slot shelves available right now. Either way, it doesn't solve my problem. If I am installing asterisk in a small to medium sized office, I would like to find a product that is easy to purchase and easy to connect. I don't want to rely on something that I *might* be able to get if I watch ebay close enough, never knowing just how much space it needs, how much I will have to pay for it, or if it will actually work when it arrives. I didn't really mean to be short in the last email, but it seems (IMHO) that there is a huge need for a current product like this. Evidently they *do* exist, at least according to the Ditech and Valient websites, but I can't seem to find anyone that actually sells them. My hope was that some of the other integrators or suppliers on this list might have found a current product that fills this need. Is everyone just using the ancient Tellabs stuff?
