Here are some generell recommendations for using any video conferencing service:
- Make sure you have a stable broadband internet connection.
- Your home wifi is probably too shaky for real-time traffic; rather use one of these
- ISDN + Video = No No
- Use a headset! Your fellow participants will hate you for echos or white noise.
- If you are in a bigger meeting (>3 part.), mute yourself when ever you are not speaking.
- We recommend using Chrome or Firefox for all our services
- We recommend to disable all privacy plugins and if necessary disable your firewall (alternatively allow the WebRTC udp-ports)
- If you want to test your headset/webcam, you recommend this Testing Service
- Don't be like this ;-)
Please see detailed descriptions of our infrastructure below.

We do not lock the webcam usage of the user, please be prudent in the use of it in larger rooms. We can lock the usage to moderators only, but at the moment preference the netiquette. As rule of thumb the more users the less webcams enabled.
Can I record my session?
Yes you can record your session. Recently we published a self service portal, where you can activate some additional features for your session, such as recording. Please read more below, where recording is described in the self service portal. For the postprocessing of your recording please open a ticket (email@example.com). We will do it for you manually and send you a downloadlink when ready. We are working on it to implement this in the selfservice portal.
How can I use the self-service-portal?
The self service portal will be opened for you when you are starting the room. You can choose between the following features:
Everyone is muted on start: self-explanatory
Everyone is moderator: self-explanatory
Registered user can start meeting: noneffective
Disable camera for non-moderators: Webcams are disabled and cannot be activated by users until the moderator enables individual or all webcams.
Disable microphone for non-moderators: microphones are all disabled until the moderator enables individual or all microphones.
Disable shared notes - editing only for moderators self-explanatory

Disable private chat - editing only for moderators self-explanatory
Allow recordings: You can enable your room for recordings and start the recording in your session. So you have to click twice: first to enable the recording in the self-service-portal before you launch your room and second you have to start recording within your session. The postprocessing of the recordings is automated since 29.04.2020 when you finished your conference. So please always finish your session to get your recording some time later. So DO NOT give the room to the next session. In this case we could not seperate the recordings. How to get your playbacklink is described below. Please notice, that the downloadlink for your recording will be implemented as soon as possible.
Allow guest: Guests are generally allowed
Access Code: This feature is for the additional protection of your session. Only users with a valid access code can enter your session. For everyone: each user has to supply this access code. User with a h_da login has to supply this access code additionally (h_da internal and external entry restriction) Only for guests: only guests have to supply the access code (h_da external entry restriction)
Activate waiting room: Please select "Approval by Moderator". The other options are useless, but cannot be disabled. Selecting "Approval by Moderator" the moderator opens a major room with a waiting room in front, like a doctors room. Each person, which would like to enter the major room, is entering the waiting room. The moderator is able to decide, which waiting person may enter the major room.
How can I get the playbacklink of my recording?
If you had started your recording within your session, the recording will be postprocessed automatically after you have finished your conference. The preparation of your playback will last some time (as rule of thumb: time duration of your record multiplied by 2). A downloadlink for your recording will be implemented as soon as possible. As logged in user, you find all your recordings in rooms.h-da.de in your personal view under the point recordings.
How can I upload a presentation?

How can I get help in rooms.h-da.de?
If you have time critical and technical problems within BBB, you can use the live-chat in the right bottom of rooms.h-da.de.
A red buttom left from the "+" means: live chat is offline.
A orange buttom means: at least one support person is online in the live chat.
A green buttom means: at least one support person has joined the conversation.
For all other problems please open a ticket (firstname.lastname@example.org).
