WebRTC enables video and audio communication using a web browser (the main ones supported being Google Chrome, Firefox, Microsoft Edge, and Opera). BUT…
Whilst WebRTC is very convenient and simplifies video usage and minimizes support, it still needs firewall tweaks and access to necessary servers:
- For clients to exchange metadata to coordinate communication: this is called signaling.
- To cope with network address translators (NATs) and firewalls.
To use our WebRTC service you will need to ensure that all those that use it have access to the address ‘stun.l.google.com’ via port 19302 (UDP/TCP) and additionally HTTPS access to ‘join.dial.vc’ and port 443 (TCP).
