Hi, Just to let you know that I did a basic test with asterisk on an OpenVZ VE and it works. We only tested SIP connectivity (it would probably be complex to have Zaptel support and I don't really need it). We were able to connect to a VoIP provider using SIP ( unlimitel ) and music on hold works. The only thing I had to change to make it work is to comment out this line in /usr/sbin/safe_asterisk: #TTY=9 # TTY (if you want one) for Asterisk to run on (I guess there is no TTY9 (console # 9) on openVZ since it is a virtual machine and TTY9 is usually a physical console (monitor)). I'll soon put my asterisk server in a VE, I'll let you know how it goes. I also use Unlimitel and ATAs to link my PSTN line and cordless phones.
