"Start audio call" and "Start video call" buttons appear when looking at the user info in a direct chat. They don't appear when looking at the user info from a channel.
There should be no audio and video call buttons, unless the service is configured.
Buttons appear in this view nonetheless.
Can be duplicated in any browser.
There's no error or crash, but it's causing confusion for the users and creates unnecessary helpdesk work.
Please advise, if required.

On firefox I also get these errors in the console

@rsimai Can you check your browser console for errors as well? Thanks!
I can't confirm this, sorry. There are no messages in my console (Firefox and Chrome) after I allow camera usage. My UC camera becomes active, I see myself, the other person gets a notification and can also activate their camera. It wouldn't work that callers can see each other which is as expected, as the services are not configured.
The problem seems to be the fact that BBB is included as an iFrame. If you right-click the iFrame and open it in a new tab it will properly ask you for permissions for your camera etc. and after you granted those it'll work in the iFrame as well. Of course this is not a way to solve this problem in production deployments
I'd rather guess that these Buttons are for RocketChat's own WebRTC-Implementation and have nothing to do with either Jitsi or BBB. See if there's something enabled under https://your-chat-server-here/admin/WebRTC
Our Chat server has all of the switches turned off and there aren't any of these Icons, with or without BBB enabled. BBB has it's own button in the dots menu.
See the rather lengthy #9632 for how I got this Idea...

This is only one-on-one calls, what about channel or private groups?

This is still an issue in newer versions of Rocket.chat (currently using RC 3.5). Could you please reopen?
