We're currently running ISA 2003. It does the job very well, but I'm aware we probably need to upgrade to one of the latest products. MS seem to have done their usual trick of confusing their product range. I understand that Unified Access Gateway 2010 is the current model is this correct? And if so, is there anything else on the horizon that we should be waiting for?
We really use the system as a firewall for our network, proxy web services for users, VPN and virtual networks. We are looking at a new IP based telephone system that runs over VOIP lines and I assume this would support this functionality?
Can some also provide any resource sites to better understand it's functionality?
Thanks,
