In about 2005, while I was IT for a startup, I worked with a counterpart at an investor (Deloitte maybe?) whose job was largely coordinating video calls in advance of meetings. We’d exchange IP addresses and SIP addresses and whatnot so that our Polycom could talk to their Cisco or whatever it all was. She and I would join 30 minutes beforehand to make sure it all worked, stand by during the meeting in case there was trouble, then come back after the execs were finished and shut it all down. The calls were at least as good as Zoom or Teams today, at the expense of two IT people and dedicated equipment. The execs never knew it not to work great. A much simpler time. We have come a long way.
