Hello,
I apologize in advance that I am not going to be able to answer your questions in great detail, however I think it would be best to redirect you to the OCS_VOIP_GUIDE.doc. This document outlines how to configure OCS, as well as outlines our supported topologies for the 2007 version of the product.
With that being said, here are the answers that I can provide at this time:
1) No, please reference the OCD_VOIP_GUIDE doc for supported configurations
2) Not a supported configuration
4) OCS requires either a Plan A or Plan B Gateway. At this time Asterisk is not a supported gateways.
5) At this time there are no third party FAX applications that have been certified for OCS.
Best Regards,
Shawn
