Our moderated product require access to specific ports. At a minimum the following requirements must be met:

  • Open TCP port 443
  • Whitelist the following domains:

*.tokbox.com

*.opentok.com

Along with the minimum requirements, opening UDP Port 3478 will give you a better experience. UDP is highly recommended over TCP for better quality audio and video. The protocol favors timeliness over reliability which is consistent with the human perceptive preferences; where we can fill in gaps but are sensitive to time-based delays.

This port only accepts inbound traffic after an outbound request is sent. The connection is bidirectional but is always initiated from the corporate network/client so it is not possible for an external entity to send malicious traffic in the opposite direction. For the best possible experience, we recommend opening UDP ports 1025 - 65535.

Make sure your router, firewall or networking device doesn't block incoming and outgoing traffic on the above ports and domains.

Whitelist the following HTTPS verification servers for our HTTPS certificate. Not doing so may cause console warnings, but should not affect the session.

  • oscp.godaddy.com
  • crl.godaddy.com

Make sure if your company uses a firewall, content router, or other networking device that filters traffic, that it doesn't block any WebRTC traffic. Some networking devices can interpret WebRTC traffic as P2P traffic and actively block that traffic, even if you have the above ports open. We've seen this issues particularly with Meraki routers blocking WebRTC traffic as described.
