Don't be crushed.

You just need to choose a platform that's supported in virtualization. Cisco's 
Unified Communications Manager, for example.

 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.
