Managing STUN server settings

Last Updated : Jun 10, 2026 |

About this task

Use this procedure to add and prioritize STUN servers for an Avaya Aura® Web Gateway location. You must also ensure that the STUN or TURN server details have been configured on the co-located Avaya Aura® Media Server systems.

If you use client side TURN, you must add the IP address of Avaya SBC as a STUN server. Avaya recommends using client side TURN whenever possible.

Procedure

To add a new STUN server, do the following:

  1. Navigate to External Access > STUN Servers.
  2. Click Add.
  3. In Address, type the FQDN or IP address of the Avaya SBC external B1 interface configured for STUN/TURN.
    Important:

    Ensure that this IP address or FQDN is accessible to the clients. These clients might use computers that are external to the enterprise and might also require a STUN server to make a call or join a meeting.

  4. In Port, type 3478.
  5. Click Save.

To set the STUN priority, do the following:

  1. From Web Gateway Location, select an Avaya Aura® Web Gateway location.
