There is a few things to be said about the digium 2400. Its not that it's a bad card, I agree that Sangoma is superior but they do not make a high density card such as the 2400 (24 ports single pci).
Most people experience issues with the 2400 because of one or more of the following a) forget to connect the additional power rail b) this is the big one "properly adjust rx and tx gains" you need to aquire a co test line number for this. If these are not properly set you will have echo issues indefinatly c) irq sharing, most Digium cards don't like to share :) d) echo can type mg2 works better than kb1 on most of these cards e) rev a echo can boards, if you have the hardware echo can version the first rev of the echo can board where terrible (you get better audio by removing it in some cases). f) HyperThreading turned on , don't ask me why.. this is something that came from Digium , they said there cards hate when hyper threading is turned on it buggers a lot of things up for them.

Had echo on the line, and Digium couldn't figure out what might have been wrong. Had issues with volume as well.
