In previous year, I used Jitsi meet on it’s official server to hold video meeting with 76 participants per s single room. It was very useful tool with such ability.
At that time I read that developer team trying to increase this capacity to more than 200 participants per single room … But now I see that they limited their capacity to just 50 participants per room ! More surprisingly, even the paid version 8x8 have same limit !
8x8 has the limit of 100. meet.jit.si has a limit of 75 for the moment.
