Network Ports
Connections made to our WebRTC cloud across all global regions use the following TCP and UDP ports. If UDP port is blocked then calls will connect over TLS rather than the more efficient protocol UDP, which can lead to quality issues with video, audio and content sharing. It is important that firewall ports are opened to servers. We have implemented technology to work if you are behind strict corporate firewalls and NAT environments. If you can't get the audio/video working inside virtual classroom, then most likely our IP is blocked by your firewall. For specific IP ranges of our global Virtual Classroom servers, contact support
