True, there is no workaround, unless you're using a UPnP firewall (ISA isn't and won't be).

I believe there isn't.

The script worked for IM versions earlier than 4.7, but not since. MS changed the VOIP technology for the IM client and it no longer works over NAT unless the remote client is non-NAT and initiates the session.

Now we are a little worried becuase this is a lot of ports. Do we actually need to open this many ports to allow clients to use the voice and video features of MSn messenger (not Netmeeting). All the clients using the voice and video service have a firewall client installed on their machine.
