10.5.Configure STUN

The STUN (Simple Traversal UDP through NAT) server is an implementation of the STUN protocol that enables STUN functionality in SIP-based systems. The STUN server also includes a client API to enable STUN functionality in SIP endpoints.

STUN is an application-layer protocol that can determine the public IP and nature of a NAT device that sits between the STUN client and STUN server.

Notice: If your gateway is behind NAT (Use Private IP), must configure the parameter. After configuring the parameters of STUN, please act Warm-Restart.

The STUN refresh time defines how long the device will send a binding request packet with discard flag on to STUN server. A binding packet with discard flag off will be sent each time when the number of binding request packet with discard flag on reach the Rebinding counts. The binding request packet is used to let the STUN server keep the most fresh client information.
