Asterisk OpenBSD
Asterisk on OpenBSD
4.1-stable
Asterisk 1.2.18 is in the (stable) ports tree.
3.8-stable
Asterisk 1.0.9 has been in our (stable) ports tree for a relatively long time.
3.8-current
Version 1.2.2 was about to go in when the timebomb bug fix release 1.2.3 was announced; 1.2.3 should be going in pretty soon.There is no support for ZapTel hardware at this point, but people are using it with SIP phones and with IAX to DID providers, for example.
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.Driver support exists in FreeBSD and will eventually make it here, if enough people need it.

I'd love to see zaptel for openbsd.

333Zaptel support needed
Currently I run 40 asterisk linux box at work, and my home box on Netbsd.
I don't know if it was really difficult to port from NetBsd driver (which are port of freebsd driver) ?
The kernel structure seems to be approximatively the same, but there are surely some differences..
So if you are motivated, I can help you. I have some hardware (currently x100p clone and several quad T1 cards) to play with :p)
