Subject: [Asterisk-biz] PRI Hardware Echo Canceller


I am looking for hardware echo cancellers for PRI's. 

I have tried to request information twice now from Ditech Communications regarding their SX-24 product but have not received any response.
( http://www.ditechcom.com/platforms/productdetail.aspx?pid=13) 

I have also emailed Valiantcom about their desktop and 1U T1 Echo Canceller without any repsonse.

What are others using for hardware echo cancellation at locations that only need 1 PRI?  Does anyone have a suggestion on a specific brand/model or supplier for 1 and 2 port T1/PRI echo cancellers?
