how to change to ringcentral video from the zoom powered meeting

What makes you think that RC Video (completely untested) is any better?

What "new Ring Central video"... RingCentral has its own platform now? They are still reliant on Zoom 's core infrastructure as far as I know.

LOL. great question. Just trying to see if there is any good answer (short of ditching) which might be needed, if there isn't a good answer.

That would be my question. The only advantage is that Ring Central isn't as well know so hackers will be less likely to hack it.

What hack(s) are you concerned about?  I've seen a legit concern about the way the installer elevates privileges on Mac, but other than that I don't believe there have been any serious security problems.  A little bit of privacy concern, but not security / hackability.  Do you know something I don't?

The documentation seems to work for me outside of changing the default in gip.

The main features that I see that are missing so far vs zoom

• control the screen
• only cloud recordings
• I don't see a way to set the password for your personal meeting id (it's there for scheduled meetings)
• I don't see a way to lock the meeting

Improvements over zoom

• browser client is very full featured computer audio, video, screen share (like teams)

edit:
I did a little poking and while by default you will likely connect with a very strong encryption (ECDH RSA AES256) for the WebRTC connection it does look like the server supports some weak cipher suites that would not pass HIPPA compliance that they talk about in the whitepaper (TLS_ECDHE_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_3DES_EDE_CBC_SHA, TLS_RSA_WITH_RC4_128_MD5, TLS_RSA_WITH_RC4_128_SHA).  I would feel a lot better if all the cipher suites had pfs.
