As Peder mentioned, Unity is only a VM platform.  I actually
started using Asterisk to replace a Cisco Conferencing
package that never worked right.  We have had it running
internally for three+ years now, and have been very happy
with the results.

I am currently using chan_ooh323, but SIP is possible if
you have CCM 4.2 or higher.  You'll also want to run
a later release of Asterisk 1.4 which has a work-around
for an odd CCM hold implementation.
