Video/audio messages with external client

Does the mattermost has the ability to make video/audio calls with people outside the company?
If so, what are the conditions?

Another thing: if the video calls are possible, could I share the screen to every participant?

Thanks for your answer!
Cheers

Hi @Krzysiek,

Yes, this is supported via plugins. More information about options is here: https://docs.mattermost.com/deployment/video-and-audio-calling.html
