Well, as I said the hardware echo cans are generally tested to comply with bellcore standards for echo cancellation, which is something that the software echo cans in Asterisk fail at (miserably, from what I've heard). It's not that it can't be done, but just rather that it hasn't been a priority for those who are smart enough to code these things. > I'm curious though: did you find that the software approach totally > eliminated echo in typical situations? I've always found one or two corner cases that fail with software echo cancellation, but by and large I am confident to say that less than 1% of our calls have any kind of echo. We are on a PRI and the telco definitely does NOT have echo cans on our span. -A. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
