negotiates with the remote communication terminal and 
selects the optimum encoding method automatically 
according to the encoding method usable by the remote 
terminal. 
This menu item is used to determine the range of encoding 
methods that can be selected by this system.

with the G.711 extended encoding method, select 
“G.711”. If this is selected, this unit selects the optimum
