I see all the comments re: latency, but I'm sure the server is only used for call setup and teardown in our cisco system. Most of the actual voice traffic doesn't go through the server. I've actually disconnected the server network cable with calls in progress and no one noticed. Not on purpose, mind you. Now if the server has special hardware or some gateway or such, then all bets are off, but in our cisco system the servers are just generic hp hardware. Voice traffic is point to point, ie phone to phone or phone to gateway. Now there could be issues if using a software conference bridge or some such and access to a voice mail system could definitely be problematic for a virtual environment.

If the phone system requires any special hardware in the PC, it's unlikely to work. For example, expansion cards for interface to analog or TDM ports. For something that's just an Internet Protocol node, it should work. expect vendor support will be the biggest issue. Phone equipment makers often act[1] rather ignorant when it comes to their PC-based platforms. You don't want to end up in a "We don't support that configuration" scenario if your phones are down. From a technical standpoint, it should be fine. OSes are already time-sliced; you're just time-slicing the OS now, too. There may be some tech details to work through. Real-time voice is very susceptible to latency and jitter, so there may be some VM tuning involved there. You prolly don't want to oversubscribe the host resources for that VM. -- Ben [1] "Act", not necessarily "are" ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
