I'd go with those two (i.e. have talkyoo ready as a fallback), with
one tweak:

- instead of hard-coding audio-only on the server, send out a meeting
  URL _different_ from the regular one, that includes the
  #config.startAudioOnly=true fragment Cloph mentioned
- plus recommend people to use desktop computers, if they want to talk
  (I suspect listen-only would still work with the Android app?)

I wouldn't do that without a proper testrun.

Same impression as Emiliano..

Hi Florian, hi all,

That alarms me a lot. My i7 4x CPU was at 8+ load while conferencing
with the test. I suspect Chrome is the main culprit there. Will try with
Chromium.

Good idea. We should try in a non-scholastic time frame (like 17.00 UTC
or something like it).

I second this one much. In the end we don't need video streams and maybe
a full-fledged audio conferencing system may cope with much more
participants and scale better.

That's BigBlueButton (https://bigbluebutton.org/), which is a more
classroom-oriented approach.
His instance is hosted on https://bbb.opencloud.lu, if of any interest.
Please ask him if you want to try it straight away (paolo.vecchi@tdf).

I've just heard more issues than with Jitsi, so...

Hello,

thanks a lot to the team for running the test and to the precious 
feedback received from Emiliano and others! I just talked to Cloph and 
will try to summarize the situation:


- the VM hardware has been bumped up

- it strongly looks like neither hosting nor server nor bandwith are the 
problem, also the traffic is normal


- it very much looks like the client is the problem

- I proposed to verify the results with a test in the official Jitsi 
Meet instance, to see if this has the same problems, although I'm not 
sure that in the current times that is reliable


For next Friday's meeting, we have several options:

- We could server-side enforce the audio only mode. Whether that helps 
or not is unclear, as people are turning off video during the meeting 
anways.


- As fallback we could use

  - talkyoo, a pure phone-based solution that served us well in the 
past. For dial-ins from countries that talkyoo doesn't provide a number 
for, there seems a workaround with Google Hangouts. This "bridging" is 
not convenient, but does the job.


  - another conferencing system Paolo is using (I don't remember the 
name currently)


  - Nextcloud Talk, as we do have a Nextcloud instance; but then, we 
don't have experience with the videoconferencing module
