I had a couple of Exchange 2010 voicemail questions from a school district from northern California replacing Cisco Unity voicemail with Exchange 2010 UM.
Where can I check if my PBX has been tested with Exchange 2010 UM?
We have an updated Telephony Advisor list for Exchange 2010. You can check SIP gateways, TDM PBXes that have been tested as well as SIP PBXes that have been tested with Exchange 2010 Unified Messaging.

I have heard Exchange 2010 UM does not work with Cisco Call Manager 5 or higher, true?
No, we have tested Exchange 2010 UM using direct SIP to CCM 5,6, and 7.
How do I upgrade to Exchange 2010 UM from Exchange 2007 UM?
It is a fairly basic process, you install Exchange 2010 UM server into the same dial plan as Exchange 2007 UM, point the SIP gateways or direct SIP PBXes to the new 2010 UM server, migrate mailboxes to 2010, migrate any custom prompt autoattendants, decommission Exchange 2007 UM server.
Exchange 2010 UM supports coexistence as well and will route any Exchange 2007 voicemails to Exchange 2007 UM servers.

Can I connect multiple PBXes to Exchange 2010 UM and leverage the same dialplan and subscriber access (pilot) number?
Yes, this works and is supported. Here is a list of supported scenarios:
