2016 - Slack adds video calls to keep up with Glip


Collaboration messenger Slack is adding one more key feature - video calling. Group video calls, for those on paid tiers, can handle up to 15 people currently, Slack says. The new feature will be available first on Slack for Mac and Windows on desktop and Google Chrome in the next few days. Those on mobile will be able to join video calls but will experience them as audio only. Video calls in Slack will have an interesting add-on - emojis. A lot of people who use video and audio conferencing for calls with work colleagues will turn on the mute button so that their random coughs and sighs or other ambient noise will not interrupt the soliloquies of their coworkers. Now if they want to make quick responses to things they won’t have to fumble around for the unmute button: instead they can offer a thumbs up, or whatever is right for the moment.
