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:
|Test your network||Audio and Video Test|
In this article :
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.
|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
*this list is subject to change so we recommend using a sub-domain rather than IPs in your firewall configuration.
We recommend whitelisting the *.icastgo.com sub-domain.
In particular, the application uses two advanced technologies:
- long running HTTP requests (Sever Sent Events)
And advanced proxy filtering or caching could interfere with these technologies.
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.
