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.

You can enable and disable the service on WEB page. 

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.
