You can add a new STUN server and set the STUN server priority from External Access > STUN Servers on the Avaya Aura® Web Gateway administration portal. 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.

You must use port 3478 when adding a new STUN server.

For more information about configuring STUN server settings on Avaya Aura® Web Gateway, see Managing STUN server settings in Administering the Avaya Aura® Web Gateway.
