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.
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"
