I've been doing research to see about virtualizing our asterisk servers. And most of the information I have googled and searched on these forums are all roughly 2 years or more old. Most the information I have found says you can virtualize asterisk and SIP/IAX will work fine, but anything that requires hardware (Digium T1/PRI cards, Analog line card, etc) is a no go with ESXI. And on the same premise any feature that requires hardware timing has issues.
Since all of the information is two years old and considering how popular asterisk and its derivites are nowadays as an easy cheap and highly effective (and resellable) VoIP/PBX/IVR/ect solution I would like to think these issues had been resolved, but since I can't find a concerete answer one way or the other after a good bit of googleing and forum searching, I figured I'd ask here.
Can asterisk be virtualized and use Hardware add on cards such as digital T1/PRI card, analog line cards, etc with the use of the newest ESXi 4 version virtual host?
