Well here's what I did to finally get some sort of ground. I was going to move the card to a different slot, when I opened up the box I saw there was a power split between the connector & the card to feed a fan in the system. I removed this split so it was straight in from the power supply. I then moved the card to another slot, and between the two, echo cancellation actually started to work.
I played with the settings a bit, then got your e-mail and noticed I was in fact using the wrong fxotune. I used the new version, switched back to MG2 from MARK2 and removed aggressive suppressor. Now I am practically echo free. Thanks for the tips, any ideas why either the power split or the card slot would keep add echo, or at least make it so my echo settings weren't taking? As soon as I modified the hardware the echo was vastly improved, then the minor modifications mentioned above wrapped it up. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matthew Fredrickson Sent: Friday, January 12, 2007 9:14 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Echo...

From your output values, it looks like you just tried the 1.2 version of it. The 1.4 version sets the remaining values. It got a pretty considerable rework between 1.2 and 1.4 and runs a lot better. So here's your order of operations: 1.) Run 1.4 (or trunk) version of fxotune on your lines. 2.) Make sure your init scripts have fxotune -s in it (to set the values when you reboot). 3.) Use the MG2 echo canceler from 1.4. 4.) And if all else fails, try the aggressive suppressor option. I recommend that as the last and final option since it's a really non elegant way of fixing it.
