The SBX uses H323 voip protocol..you have to open a ton of ports for the voice connection to work, that is why hanging it out in front of a firewall works best,
1719 (UDP) RAS signaling port, specified in DNS and also the default port for H.323 clients
11720 (TCP) Call signaling port, specified in [RoutedMode]->CallSignalPort
56000-56999 (TCP) Dynamic H.245 signaling ports, specified in [RoutedMode]->H245PortRange
55000-55999 (UDP) RTP/RTCP ports for proxied media, specified in [Proxy]->RTPPortRange
2776 (UDP) RTP multiplexing port, specified in [Proxy]->RTPMultiplexPort
2777 (UDP) RTCP multiplexing port, specified in [Proxy]->RTCPMultiplexPort
The old Vodavi IP voip gateway that used H323 used these ports:
TCP Ports 22, 23, 77, 111
UDP Ports

You almost have to stick the SBX in a router's DMZ if anything outside of your vpn is trying to reach it.
