To ensure a better experience, icastGo uses many advanced features of your browser.
There are certain technical requirements that must be met, such as using a relatively modern web browser.
These prerequisites are summarized on this page
We strongly advise you to perform both technical tests:

Network requirements
icastGo is a platform hosted on the cloud and therefore theoretically accessible through any Internet connection. However, some corporate firewalls may need to specifically authorize certain ports.
Firewall configuration
| 443 (TCP) | HTTPS outgoing port |
| 40000-49999 (UDP)* | WebRTC UDP outgoing ports for transmitting video and audio from a browser |
| 40000-49999 (TCP)* | When outgoing UDP is not available WebRTC TCP outgoing ports for transmitting video and audio from a browser |
*If the 443 (TCP) post is the only available outgoing port, then the WebRTC connection will be established on this port as a fallback.
Meeting server IP addresses
Meeting servers are accessible on the meet.icastgo.com domain.
As of May 10, 2020 the IP addresses of the servers* are as follows
52.60.80.75
52.60.105.48
15.222.227.50
15.222.156.13
15.222.165.146
15.223.111.248
15.222.192.212
15.222.198.204
35.181.91.85
3.7.148.67
15.188.121.49
*this list is subject to change so we recommend using a sub-domain rather than IPs in your firewall configuration.
Proxy configuration
We recommend whitelisting the *.icastgo.com sub-domain.
In particular, the application uses two advanced technologies:
- long running HTTP requests (Sever Sent Events)
- WebSockets
And advanced proxy filtering or caching could interfere with these technologies.
Browser requirements
Important note: icastGo is compatible with all browsers for participants.
However, for speakers who use their browsers to transmit audio and video or simply to collaborate live during a webcast, we recommend the latest versions of the following browsers:
- Google Chrome version 61 and later
- Mozilla Firefox version 60 ESR and later
- Microsoft Edge version 74 and later
- Opera version 53 and later
- Apple Safari version 11.1 and later on macOS. Apple Safari on iOS 11.2 and later.
