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:

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
