For Codec and Board Devices it should be possible to amplifi the microphone Input to the local Audience. Additional Hardware is not necessary for a pleasant Administrator, Enduser and Audience experience.
In big, crowded rooms the speaker is usually amplified. At the moment this needs additional hardware, which could not be nessesary if the micorphone-inputs are (optional) amplified.
Furthermore the control of the all aspects of the communication interfaces (camera, audio) can be controlled by the user.
