Easy... just unplug the ethernet from the ISA and plug it into the phone. Then all your ports are open. Yes, you would need another IP address from your provider.

VOIP does not play nice with ISA, or just about any other firewall for that matter. You usually have to revert to hanging your VOIP phones out on in a DMZ with a real internet IP address.
