'''Overview'''
The call waiting module allows an additional call to come in on the same channel。<br/>
The Call Waiting module provides an option to turn call waiting on or off. There is no "Call Waiting" module under the GUI menus. Instead, settings are controlled in the Feature Codes module, Extensions module, and Advanced Settings module. Users can activate/deactivate call waiting through feature codes.
