Avaya recommends using client side TURN instead of sever side TURN whenever possible. If you use server side TURN and WebRTC browsers are behind a firewall that blocks UDP traffic, you might experience issues with WebRTC calls. Clients are loaded from your browser and no installation is required on client users' computers.

Use these sections to enable client side TURN for WebRTC browsers outside your enterprise firewall.

To enable client side TURN, you need to open TCP port 443 on the external firewall.
