prlanzarin aeb2dabb62 fix(audio): forcefully disable stereo when using Vosk transcription 
The current Vosk CC provider does not support stereo mic streams
(pending investigation as to why).

This commits makes sure stereo is forcefully disabled via SDP munging
only when transcription is active and using Vosk. Having it disabled
in the server side (FreeSWITCH) is not enough because the stereo parameter
is client mandated and replicated by FS on its answer. So we need to
make sure it's always disabled for the time being.
SFU audio does munging server side (and stereo is always off), so no changes
needed there.

The rest of the providers (except WebSpeech) need to be validated against
stereo audio as well.
This is also intended to be temporary - ideally this needs to be fixed in
mod_audio_fork/Vosk/wherever this is breaking.

BigBlueButton

BigBlueButton is an open source web conferencing system.

BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard controls), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboard, and breakout rooms.

Presenters can record and playback content for later sharing with others.

We designed BigBlueButton for online learning, (though it can be used for many other applications as well). The educational use cases for BigBlueButton are

  • Online tutoring (one-to-one)
  • Flipped classrooms (recording content ahead of your session)
  • Group collaboration (many-to-many)
  • Online classes (one-to-many)

You can install on a Ubuntu 20.04 64-bit server. We provide bbb-install.sh to let you have a server up and running within 30 minutes (or your money back 😉).

For full technical documentation BigBlueButton -- including architecture, features, API, and GreenLight (the default front-end) -- see https://docs.bigbluebutton.org/.
