The mothership is killing Webex at the beginning of July. I can't profess any big love for it, leastways until they forced Teams upon us (we used to have Slack). It's notable that compared to Slack, all the groups and everything that used to exist have now died off or are reaching the defined state of moribund that if they moved you'd shout 'argh zombie.'
Call quality is crap too and in the cost-saving wisdom of the mothership they're dropping dial-in numbers, so it's computer only.
Of course, I get stuff elsewhere in Zoom, Skype, Blue Jeans, Google, blah blah. They all seem somewhere south of intuitive.
