I have successfully deployed OCS 2007 R2 standard with a consolidated EDGE server in our DMZ. Everything works except for the things that need an ISA server to work (distribution list, whiteboard, handouts, etc..).
I am doing a PR for ISA 2006 from Microsoft. We currently have a Cisco ASA 5540 firewall. Is there anyways to just use that instead of buying a server? Is there anything else I could do beside ISA 2006?
