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
