Setting STUN Server Parameters

Setting STUN Server Parameters


The STUN server has been deployed.

For details about how to deploy the STUN server, see the eSight Product Documentation.


In an actual network environment, the Application Control Server (ACS) server is generally deployed on the Internet. IP phones are deployed behind NAT and cannot directly access the Internet for connecting to the ACS server. In this case, you need to use the Session Traversal Utilities for NAT (STUN) protocol for NAT traversal so that IP phones can directly communicate with the ACS server in P2P mode, without forwarding by other public servers.

When being separated from the ACS server by NAT, IP phones can use the STUN server as a communication transfer server so that the ACS server can perform cross-NAT management on IP phones. When IP phones connect to the ACS server, the ACS server pushes STUN server parameters to IP phones.


  1. Log in to the eSight web management system as the administrator.
  2. Choose Resource > Collaboration Resource > Terminal Device Management.
  3. In the navigation tree on the left, choose System Configuration.
  4. In the STUN Server Parameter Configuration area, set Enable STUN to Enable, and set STUN minimum period (second) and STUN maximum period (second), as shown in Figure 4-2.


    You can deploy a configuration file delivery task to deliver STUN Keep-alive Period to IP phones.

    Table 4-1 STUN server parameter description



    Enable STUN

    Indicates whether to enable the STUN function. When the STUN function is enabled, the STUN server is used as a communication transfer server in the NAT environment.

    STUN minimum period (second)

    Minimum period for IP phones to periodically send BindingRequest to the STUN server.

    You are advised to use the default value 10.

    STUN maximum period (second)

    Maximum period for IP phones to periodically send BindingRequest to the STUN server.

    You are advised to use the default value 3600.

    STUN server IP address

    Current IP address of eSight. This parameter does not need to be modified.

    STUN server port number

    The default value is 3478. This parameter does not need to be modified.


After an IP phone connects to eSight, log in to the phone web page as the administrator, choose Advanced > TR069, and check the STUN server parameters delivered by eSight, as shown in Figure 4-3.
