8.3.3.3 STUN Config
STUN support is configured in this page.
STUN – Simple Traversal of UDP through NAT – A STUN server allows a phone in a private network to know its public IP and port as well as the type of NAT being used. The phone can then use this information to register itself to a SIP server so that it can make and receive calls while in a private network.
