Network Ports
Connections made to BrainCert WebRTC cloud across all global regions use the following TCP and UDP ports. If the UDP port is blocked then calls will connect over TLS instead of the more efficient UDP protocol. It can lead to quality issues with video, audio, and content sharing. It is important that firewall ports are opened to BrainCert 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 the virtual classroom, then most likely our IP is blocked by your firewall. For specific IP ranges of BrainCert's global Virtual Classroom servers, contact support.
