A new dialog will be displayed for the users to configure “Basic” settings and “Advanced” settings. “Basic” 
settings have the same configurations as displayed when manually creating a new device, i.e., account, line 
key and MPK settings; “Advanced” settings allow users to configure more details in a five-level structure.
