MSN requires SIP gateway to communicate video n voice which is not supported in ISA . However voice communication can be done if opponent party sends you to join voice request n u accept then voice session will be initialised.
However you can use netmeeting for better video n voice communication. There is a very good artile of thomas shinder regarding configuring Netmeeting in articles section.
You need to create the following protocol definitons (under Policy Elements):
1. Yahoo! Voice #1 TCP Port 5001 Outbound
2. Yahoo! Voice #2 TCP Port 5000 Outbound
3. Yahoo! Voice UDP UDP Port 5000 Receive Send
4. Yahoo! WebCam 1 TCP Port 5100 Outbound
5. Yahoo Messenger Chat TCP Port 5050 Outbound
6. Yahoo Voice UDP 2 UDP Port 5000 Send Receive
7. Yahoo Webcam 2 UDP Port 5050 Receive
8. Yahoo Webcam 3 UDP Port 5050 Send
9. Yahoo Voice UDP 3 UDP Port 5001 Send Receive
10.Yahoo Voice UDP 4 UDP Port 5001 Send
11. Yahoo Voice UDP 5 UDP Port 5001 Receive
12. Yahoo Voice UDP 6 UDP Port 5001 Receive Send
After you create these you need to add a protocol rule for them in Access Policy. It should work. Dont forget to install Firewall client in your workstation and connect Yahoo Messenger with NO PROXY.

Trying to add the above parameters in to ISA 2004 beta for Yahoo messenger but if i try to add them as an additional messaging protocol i get an error about the session initiation having to be in the same direction. Am i going about this the right way? Where and how should i be adding these to get Yahoo messenger working?
What should be primary and secondary?
PS Be nice if MSN messenger worked but if not then i will test Yahoo's to see how well it performs, shame Microsoft not supporting their own product!

Tried this again, i added a user defined protocol. Then added all the parameters above but when i come to save it comes up saying ISA server can not save the properties. When i click on the details button it says "The primary connections for a protocol must apply to traffic coming from the same direction"
