Is it possible to use the IP Phone behind a IP-Sharing device (NAT) ?
Yes, our IP Phone can work behind the IP-sharing device directly without doing any additional configuration on the IP-sharing device, you just plug in the IP Phone, and it will play. The NAT-passing-through technology works for both the ET-747H(H.323) and ET-747S(SIP) models if the proper VoIP service provider is selected.
