Receive VOIP call inside Firewall

We have a pc client that runs on Microsoft Windows (W98, ME, 2000, XP) that uses [url removed, login to view] protocol which is running on Linux server to receive and make VOIP calls. Currently it can not receive calls if the pc client does not have a real IP address assign to it. I mean it is a case when it is behind Firewall / Router and it does not perform NAT.

We are looking for a solution that can allow our PC client which is behind firewall to receive external VOIP calls.
