Codec
The Avaya codec compresses outgoing video and audio content and data, transmits this
information to the far end of a call, and decompresses incoming information. You should not
need to interact with the codec once it has been properly installed in your environment.
Third Party Display
A third party display connected to the Avaya codec enables you to access the user interface
and view video images during a video call. A second display may be connected to the Avaya
codec if the system supports more than one display.
