Open Source Drivers For Devices w/ Mulitiple Audio Inputs?

krystal_blade asks: "I've seen a couple of proprietary recording systems (for phone lines) made by Denro and Stancil that have the capability to record over 40 channels of audio simultaneously. They run around 25K $$ to own, and tech support is atrocious (around 250 dollars a half hour) These programs are almost all integrated into Microsoft-based operating system. Is there currently an open source solution to this? (As a side note, I'm also looking for a Linux compatibility solution to mulitiple channel audio boards)"
