Ports for video calls and livestreams

Virtrex uses WebRTC for video calls and livestreaming. Please note: There is an HLS fallback for livestreams. 

WebRTC is an open source technology for bidirectional low-latency communication between devices.  

Firewall and Ports

We do understand that many organizations prefer to route their network traffic through a firewall to improve privacy and security. However, for video calls a peer to peer connection is required.

Therefore it is necessary that the following ports are open:

• HTTPS Port: 443 (UDP and TCP)

Proxy and VPN

Because our video call service is peer to peer, not having a consistent IP address can cause problems connecting to calls.

If you are in any kind of a VPN or using a proxy, it is most likely that you will experience connection issues for video calls. 

We suggest to turn off your VPN or Proxy when having video calls and turn it back on after the calls are finished.

Speed and Latency 

To ensure video calls are in a good quality it is required to have at least the following upload and download rates:

• Outbound (upload): 2.0 Mbps 

• Inbound (download): 2.5 Mbps

For latency, you will want to make sure you are experiencing less than 100 ms on your network for the best experience. Up to 400 ms is acceptable, but not ideal for high-quality conversations.
