WebRTC client side TURN configuration
Use these sections to enable client side TURN for WebRTC browsers outside your enterprise
firewall. Clients are loaded from your browser and no installation is required on your computer.
To enable client side TURN, you need to open TCP port 443 on the external firewall. Server side
TURN uses a range of UDP ports and consumes less Avaya SBCE resources than client side
TURN. However, if a WebRTC browser is behind a firewall that blocks UDP traffic, you might
experience issues with WebRTC calls if using server side TURN.
Avaya recommends using client side TURN instead of sever side TURN whenever possible.

Prerequisites
Before configuring WebRTC client side TURN settings, do the following:
• Add Avaya SBCE to the Avaya Aura
®
Web Gateway. For more information, see
Avaya Session Border Controller for Enterprise to the Avaya Aura Web Gateway
on
page 122.
• Configure one B1 interface IP address on the Avaya SBCE.
Additional internal A1 interfaces are not required. Use the same A1 interface IP that you used
for load monitoring. For more information, see
Configuring Avaya SBCE load monitoring
