I commented out the echotraining line in chan_dahdi.conf and it fixed the problem. this issue took some looking but apparently when you do a pstn-setup trixbox uncomments the line (which I believe was commented out by default, or atleast it was in earlier versions that I installed). I think I will experiment with a lower setting to see if that helps out the echocancellor, if not I atleast I know it works alright without it.
