10 days ago+1 for Jitsi. Works well, user-friendly, lots of features without looking complicated, not too resource-hungry, lots of ways to extend it. All the other person needs it to click a link, enter a name and allow microphone/camera usage one time. There’s also an app for Android and iOS, though you can just as well use a mobile browser.
Trade-in deals mostly suck around here. I hand my ‘old’ phones down to friends and family, who hand theirs down to their kids. Their kids usually get a ‘new’ phone when their old one has stopped working or is really, really showing its age. I assume this system is representative of a quite sizeable part of society, so I’m not sure how much to read into those trade-in statistics.
