Audio and video is impaired

If the transmission could be established, but there are impairments, then there is usually a bandwidth problem or your device cannot provide the required performance.

**Impairments in your audio and video connection are noticeable through stuttering, sound distortion and feedback. The following reasons may be the case for each affected subscriber.

We recommend the following checks to find the cause:

• For Wi-Fi: Do you have good reception? Reduced signal quality has a significant impact on the bandwidth. The Wi-Fi signal symbol provides information about the reception to the router. The signal quality deteriorates as the distance to the router increases or if there are too many partitions between the end device and the router. An Internet connection via a LAN cable is generally recommended.

• Is your bandwidth high enough? Good Wi-Fi reception (reception to the router) does not mean that you have a high bandwidth. The bandwidth performance can be determined using our system check, for example. Alternatively, an online service can also provide you with information. You can search the Internet for “internet speed test”, for example.

• Does your bandwidth fluctuate? At what time did the problems occur? Are there any construction sites in your area? Are there any known problems with your Internet provider?

• Does your end device provide the required performance? You can find the required system requirements in the menu on the left under "General".

The audio and video connection is interrupted.

If the audio and video connection is interrupted, please wait briefly. The system will usually reconnect itself. If this does not happen, switch the video off manually using the button on the video tab and switch it back on again after a few seconds. If the sound and video are still not still do not work, briefly exit the session and re-enter it. If the sound and video still do not work, call the session partner by phone. The telephone numbers are listed on the Video tab in the “Alternative connection” section. Therefore, always enter telephone numbers when creating new contacts or maintain your own account information yourself.

The quality of audio and video is not satisfactory.

Due to poor connections and/or low bandwidth, it may make sense to do without the video image. Simply do not switch on your cameras to use audio-only connections.

The other participants can't hear me well.

Use a headset with microphone and loudspeakers. Standard microphones on laptops generally deliver poor quality and pick up ambient noise.

Feedback occurs

Feedback is noticeable when participants hear themselves or other participants several times.

This effect can occur if participants are not using a headset and the speakers on your device are too loud. The sounds/voices from the loudspeaker can be recognized by the microphone and played back in the session.
