Does this mean that video chat will not work at all with HipChat in closed networks?

This question is in reference to Atlassian Documentation: One-to-One Video Chat

Will HipChat video chat work without internet connection?

[Steffen Opel _Utoolity_ · Accepted solution]

Yes, due to currently using an external provider for its video capabilities, HipChat Server still requires some internet connectivity for video as outlined in the HipChat Server FAQs, see Does HipChat Server need outbound internet access?:

HipChat Server uses outbound internet access for the following reasons:

• Fetching upgrade information from Atlassian
• Fetching integration listings from the Atlassian Marketplace
• Routing video traffic through our Cloud video server
• Sending mobile notifications for Android and IOS devices

[emphasis mine]

This is further confirmed in the referenced System Requirements, see Outbound TCP Ports:

• Chat client systems must meet AddLive's connectivity requirements for video and screen sharing

I would hope that this might change some day due to Atlassian's recent acquisition of Blue Jimp & Jitsi.org, however, I'm not aware of any roadmap details in this regard.
