Asterisk versions shipped on recent OpenBSD versions:

5.0-stable
Asterisk 1.8.5.0 is in the (-stable) tree OpenBSD ports tree.
Why OpenBSD?
OpenBSD is well known as the most secure operating system around (yes, more so than Linux or MS-Windows). Many of us run OpenBSD as a server O/S (and even sometimes as a desktop O/S), so it makes sense to keep running it even when adding services that would appear to need special hardware.
At this time, no driver exists to user either Digium or Sangoma hardware with Asterisk. Without the hardware docs is very difficult to see a native driver part of the tree for it.
