You're oversimplifying it.
Your MAC is anything but "just another IP-connected device".
I seriously doubt you'll be able to reprogram the Nokia from its current protocol.
VOIP through ISA requires either:
1 - an application filter that understands the protocol
2 - the ability to run the ISA Firewall Client
..and sometimes both...

I don't understand the distinction, so please explain why my Dialpad (also a VOIP application) works on Windows if I just open the needed ports... Think of my Macintosh client as just another IP-connected device. I need to connect the external VOIP server to my IP-connected Macintosh using server publishing rules, which I've attempted. I'm missing something. Can you give me a high-level overview of what those steps are? I need a protocol definition to open the ports, that I know. What else? A desination set? A server publishing rule? We're close to the solution, but I could use that last extra piece of data to make it work, and I'd appreciate your assistance.
