I have a GPX 2020 as well as a GPX 2000 with one Sipgate A/C on it and 3
other providers.
Although I don't use Sipgate a lot it is still there and working.
They should traverse OK without opening those ports up in my experience.

I assume that these phones are connected before the SBS 2003 Server. Or how
is the SBS box connected.
2 NIC system with WAN/LAN ?

Just musing
