We need the voiceUserId (memberId) in IN_CONFERENCE callState events so
that the SFU can bypass dialplan-level mute states when transferring
between breakout rooms.
Add memberId to VoiceCallStateEvent when applicable. For CHANNEL_STATE
events that do not carry it (RINGING, HANGUP), memberId is an empty
string.
This is an initial, experimental implementation of the feature proposed in
https://github.com/bigbluebutton/bigbluebutton/issues/14021.
The intention is to phase out the explicit listen only mode with two
overarching goals:
- Reduce UX friction and increase familiarity: the existence of a separate
listen only mode is a source of confusion for the majority of users
Reduce average server-side CPU usage while also making it possible for
having full audio-only meetings.
The proof-of-concept works based on the assumption that a "many
concurrent active talkers" scenario is both rare and not useful. With
that in mind, this including two server-side triggers:
- On microphone inactivity (currently mute action that is sustained for
4 seconds, configurable): FreeSWITCH channels are held (which translates
to much lower CPU usage, virtually 0%). Receiving channels are switched,
server side, to a listening mode (SFU, mediasoup).
* This required an extension to mediasoup two allow re-assigning producers
to already established consumers. No re-negotiation is done.
- On microphone activity (currently unmute action, immediate):
FreeSWITCH channels are unheld, listening mode is deactivated and the
mute state is updated accordingly (in this order).
This is *off by default*. It needs to be enabled in two places:
- `/etc/bigbluebutton/bbb-webrtc-sfu/production.yml` ->
`transparentListenOnly: true`
- End users:
* Server wide: `/etc/bigbluebutton/bbb-html5.yml` ->
`public.media.transparentListenOnly: true`
* Per user: `userdata-bbb_transparent_listen_only=true`
Now it`s called AudioFloorChanged* to properly reflect its role
Add fields to carry the floor state (boolean) along with the uID and vID to be able to send events for a floor takeover and a floor surrender
This change introduces a config file
`/etc/bigbluebutton/bbb-fsesl-akka.conf` which reads the default config
from packages and allows operators to keep their own config file changes
across package upgrades.
bbb-conf is adjusted to deal with this change.
The lack of handling to check whether the user was a dial-in user when answering akka-apps periodic member probes was making it use an arbitrary default (callerName) as the userId, explicitly violating the convention that dial-in/outs should have v_memberId userIds
That would botch whichever added janitorial tasks that operated upon akka-apps GetUsersStatusToVoiceConfSysMsg probes
We need to increase the length of the voice conference. If we have lots of meetings running,
there is a high chance of collision.
Need corresponding changes to FreeSWITCH dialplan.
In bbb_echo_test.xml, change to `expression="^echo(\d{5,11})$"`.
In bbb_conference.xml, change to `expression="^(\d{5,11})$"`.
The /healthz returns information is we are able to send and receive message to/from freeswitch.
The /status returns information about freeswitch version and uptime.
