Can firewall punching work without proxying all traffic over the server?

> Well, if there's only 2, maybe 3 of you...

Do you mean for more than 3 - the call/video is routed through the server and would consume server bandwidth? If so how is jitsi paying for all this if it is free?

I can hook your business and anyone remote up with free sip LCD screen desk phones, usually polycomm and unlimited long distance, SD-WAN managed data if needed business phone lines with app for all phones, desktop soft phone and video bridge from Gotomeeting for s fraction of what I was paying before. I just helped a 500 employees company get 500 new phones and cut their phone bill by over half. They were being charged $25 per line, $5 per phone lease and even being charged for ac power adapter... Made the switch and saving them thousands a month with an awesome world wide network that also includes pro gotomeeting accounts for each employee. They're less than half what they were paying and taxes also cheaper and no surprise fees... Message me or call me if you want a referral. I'm looking at jitsi as a way to help my daughter's connect with their teachers. I know zoom in what everyone is pushing now because it's just so easy but it also costs if you go over the minutes... Not much though. I wanted to offer free... Willing to hear any advice for integrating edX platform with jitsi
