To assign function types, specify ext key type IDs which start with or without a symbol ”+”. For
example, “+2,15,16,7,4” or “2,15,16,7,4” means only “N/A”, “Forward”, “Line”, “BLF”, “Recall”, “Hold”
types are available when you configure ext keys.
To remove a function type, specify ext key type IDs which start with the symbol “-”. For example, “-14,
5, 2” means to remove “Intercom”, “DND”, “Forward” types from the ext key types list. These ext key
types are not available when you configure ext keys.
Note: Multiple ext key type IDs are separated by commas. N/A type is always kept.
