Programmable Keys Configuration
For T23P/T23G/T21(P) E2 phones, Cancel key can be configured only when “features.keep_mute.enable” is set to
0 (Disabled).
For other phones, Mute key can be configured only when “features.keep_mute.enable” is set to 0 (Disabled).
The following table lists the parameters you can use to configure programmable keys.
Parameter
programablekey.type_range.custom <y0000000000xx>.cfg
Description
It configures the list for available programmable key types when configuring programmable keys.
To assign function types, specify programmable 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 programmable keys.
To remove a function type, specify programmable key type IDs which start with the symbol “-”. For
example, “-14, 5, 2” means to remove “Intercom”, “DND”, “Forward” types from the Dsskey function
types list. These programmable key types are not available when you configure programmable keys.
Note: Multiple programmable key type IDs are separated by commas. “N/A” type is always kept.
