I have an I1220 linked to a BCM50 via public IP with port forwarding to the BCM LAN IP. The phone links up fine and all features work, but I get no audio. I had the IT person ensure that all ports needed for voice paths are open, buyt still nothing. Any suggestions on what I am missing?
 
You would need VPN site 2 site or NAT/VPN phone . It would be almost impossible to get the hard phone to work behind NAT as your RTP/RTPC would need LOTS of ports to be opened
