STUN Inquiry
Using “STUN Inquiry” to detect your IP sharing device’s NAT type and communication between STUN
server and client (built-in SmartVoice gateway).
NOTE:
If detected NAT type is “Symmetric NAT”, then the gateway is not able
to traverse the NAT of your Internet sharing devices. This is not a flaw of the
gateway’s design, but nature of STUN protocol design.
