Video streaming in security-conscious settings (whitelisting)

Due to either your own or your customer’s IT and security requirements, you may need to take special care to avoid triggering firewalls, by pre-testing your connections and whitelisting IP addresses.

The information below is offered for your convenience and may change as a result of changes to third-party platforms mentioned (e.g. Vonage and Twilio). 


AIRCast - Test the connection

To help prepare for trouble-free connection, Vonage offers this general pre-call test to evaluate network latency and bandwidth, and troubleshoot any potential problems: https://tokbox.com/developer/tools/precall/ 

This Vonage guide is designed to help you allow connection even when either you or your attendees are on strict networks and/or devices: https://tokbox.com/developer/guides/restricted-networks/ 


Whitelisting

For Vonage, there are recommended ports and domains to whitelist, and a number of other connectivity requirements. This article has more information:

The OnAIR portal has other domains that should remain unblocked (whitelisted) to help prevent connection problems. These are the minimum firewall access requirements:  

*.video.wowza.com 

[alias].eventsair.com

azurewebsites.net 

cdn3.wowza.com 

endpoint.twilio.com 

eventlive.eventsair.com 

eventsair.com

eventsairmobileaueprod.table.core.windows.net

global.vss.twilio.com

gstatic.com 

mobile-endpoint.twilio.com

msecdn.net

onairprod.azurewebsites.net 

onairprod.queue.core.windows.net 

opentok.com 

portalapp.eventlive.eventsair.com 

sdkgw.us1.twilio.com

tokbox.com

twilio.com

vonage.com 

windows.net 


PLUS 

Port 1935/1934 for RTMP (only if required)

Otherwise services do not use reserved ports and communicate over 80/443/8080/8443. 

If you’re using Twilio for meetings or live support, you should ensure the Twilio and Vonage domains listed above are whitelisted, and also use the Twilio network test:  

networktest.twilio.com
