Network Infrastructure

Boostlingo Events uses simple WebRTC communication for streaming video and audio.

Following here are the requirements to have Boostlingo Events WebRTC communication working behind a network firewall.

The following requirements must be met:

• Open TCP port 443, and ideally UDP Port 3478 as well
• Whitelist the following domains:
  • *.boostlingo.com
  • *.cloudfront.net
  • *.zopim.com
  • *.tokbox.com
  • *.opentok.com
  • *.vonage.com

UDP is highly recommended over TCP for better quality audio and video. The protocol favors timeliness over reliability which is consistent with 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.
