Middle managers not adapting. When my old job when remote for Covid, my manager would hold telecons, despite having access to videoconference software with the capability to document and screen share (IT setup BigBlueButton ).

Big Blue Button (https://bigbluebutton.org) is one. We actually used it at work for meetings but it seems they have since pivoted to be for more virtual classroom. I agree though, even that would need decent IT talent to setup and maintain. - Source: Hacker News / over 1 year ago

Take a look at Yac: https://yac.com/. Seems like what they were built for. In fact one of their YouTube videos even covers asynchronous meetings via audio. Source: almost 3 years ago
