I've only used Sangoma with hardware echo cancelation, but I did find I had to manually tune my cards. In my case using a test tone number was of no help, rather I just listened in on calls in progress and used ztmonitor to see where the levels were and adjusted things until I had a good level and the sound quality was acceptable. Until I did the manual tuning I had serious issues of static and background noise on several lines, but not all. I don't blame this on the Sangoma card, but rather on the line quality as I run Sangomas in other locations and have never had to do any tuning there, they have just worked. -chris <www.mythtech.net> -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
