Sadly, some users are stuck. For instance if you have Dialogic D240SC/T1 Rev 1 cards then the latest drivers you can get are the 5.x and they are very picky about kernel versions, streams libs, etc. If you want to build a supported system, you must start with Red Hat 7.2/7.3 and must, among other detailed steps, apply specific kernel patches. Or you can go through a similar set of steps on Windows. I'll take Linux - even an old version. Fortunately I have it on authority of an Intel employee that they will be open-sourcing the Dialogic drivers sometime in the next year so over time this problem will probably disappear. Cheers, Steve
