Hi all

How would you secure VOIP using the ISA server 2004?

Please could you also explain to me how voip works with isa in terms of a call coming in from the outside, how does the isa server know to open voip ports when an incoming call comes in> I am using voip in my network and the phone is working through voip for both incoming and outbound calls. I have only configured the voip phone with full internet outbound access but I want to find out how the incoming call is let through by isa.
