Hardware

The hardware you use for calling plays is very important for the quality of the calling experience. A good quality microphone will improve the audio quality, and the resolution of the video camera will affect the quality of the video stream. Similarly, the screen resolution affects the quality of the screen-sharing experience.

See the following guidelines on how the hardware affects a call. Please note that the quality of the microphone does not change the bitrate but will affect the audio quality.
