Hello all, Currently I work at a site with over 500 analog phones. We are now shopping for a VoIp system to replace our current PBX. I am currently looking at the Nortel Succession Package. I see that the Gateway box runs Windows 2000. I looked at other VoIp solutions and they also base their technology on Windows 2000. First thing that worries me is Security. Could a virus take down our phone system if it was release on our network. Is there a way I can seperate my Data network & VoIp Network from each other?
