Might this work...
Put a low-end box in between, and IP route to an internal NIC.
Cable modem (public IP) -> (nic1) voip box
voip box (nic2 10.0.0.1) -> (nic3) ISA
ISA (nic4 192.168.0.1) -> internal
Oversimplified, of course

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.

If you figure this out you would be ahead of just about
everybody. 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.

Hi
I have a VOIP phone on my internal network. It
has a fixed IP
It seems that from one phone to another and
Service provider to another different ports are needed
Can anyone tell me how to open ALL port to the
IP of this phone or of some way to find the ports I need. Ports 5060 and
20222 TCP In and Out are needed but from a sniffer it seems to from to
use UDP ports etc
The VOIP phone is a GrandStream BudgeTone-100
Appreciate any help
William
