[cisco-voip] Collaboration Endpoint (CE) 9.0 and Captive Portals

[Anthony Holloway]

I just upgraded a DX80 to ce9.0.1.4c1e2ba and I'm noticing the following
warning:

Now, in this environment, yes, there is a proxy sitting between the hosts
on the network and the internet.  So, this is not a total surprise.

However, it was not doing this on CE8.x.

When I packet captured the DX80 for a bit, I saw DNS lookups for
clients3.google.com, and then requests for HTTP GET
clients3.google.com/generate_204

A quick internet search brings up this web page:
https://www.chromium.org/chromium-os/chromiumos-design-docs/network-portal-detection

So, is Cisco's CE software built on top of Chromium OS?  Either way, why
does the DX80 need access to the Internet at all?  The release notes, admin
guide, and bugsearch were no help.  So, now I'm relying on your own
personal knowledge and experience.  Thanks.
