VoIP over satellite works very well. Take a look at TCP spoofing boxes this will speed up the 540ms lag. Ensure your design looks at all of the Qos issues and if you have any other traffic (HTTP, FTP....) CE-507 for every 1meg. If price is no object I would do the following:

Sat Hub

CCM 3.2.2

Unity with AMI

Gateway H.323

Gatekeeper

Switch Catalyst 3550 EMI

CE-507

Voice Network Management Software

Sat Link with TCP Spoofing

|

Gateway Router 2621 (SRST with FXO Ports (E911))

Unity with AMI

Catalyst 3524PWR

CE-507

APC Master Switch (Remote Power Off)

APC UPS

Phones 7905 , 7910 or ata186 (if you limit to these models no Service bwt issue)

Unity Networking is fun but if sat link goes down (any issue sun flairs heavy rain tornados ....etc) or all bwt taken up with calls the voice mail can be push at a latter date.
