Good point Alex.  I should say this is not for a ITSP.  I work in
Education in Oregon, and we are working to improve the communication
between schools in the state.  We currently have an ageing video
conferencing set-up using H.323.  We need something to act as an
external presence for roaming users and inbound calls from other
agencies for both voice and video.  SIP would be preferred, and the
H.323 video devices that support SIP will be converted.  In the end,
we would like to come up with a simple software solution that we could
give to other educational agencies so we can all communicate.
Purchasing an ACME is out of the question, not that I have priced
them, but I don't think I can get one for free...  (However, tax
deductible donations are welcome =)

Here is what need:
 - Voice and video support
 - Proxy
 - B2BUA
 - NAT Traversal
 - SIP
 - CDR

These things would be nice:
 - H.323 support
 - Transcoding
 - Simplified Management

What is not needed:
 - Auto Attendant
 - Conferencing
 - Stateful fail-over

There seem to be a lot of solutions out there, and hopefully the
experience of the list can help narrow down to what actually works.
Thanks for you help!
