l ExtX@Y (X stands for the serial number of expansion module key, Y stands
for the serial number of expansion module; For
T48S/T48G/T46S/T46G/T29G: X ranges from 1 to 40, Y ranges from 1 to 6;
For T57W/T54W/T53W/T53/T48U/T46U/T43U: X ranges from 1 to 60, Y
ranges from 1 to 3; @Y can be omitted if there is only one expansion mod-
ule connected to the phone.)
l Menu (You can enter the menu by executing this command at any interface
except the non-executable situations. For example, entering menu is
blocked during an active call.)
l Home (You can return to the idle screen by executing this command on the
dialing screen for T57W/T48U/T48S/T48G phones)
Example: $KDialPadPound$ means pressing the pound key.
Note: If a key (for example, Redial key) is not found but the function is avail-
able, the phone will perform the corresponding action. If a key is not found
and the function is unavailable, the execution of the action string will be
ignored.
$I<menu item ID>$
The action is to position and enter the desired menu item.
Each menu item has a unique identifier on the IP phone, and you can con-
figure this parameter according to the system-defined menu item ID. If the
menu item ID is not defined on the phone or there is no matched menu item
on the current screen, the execution of the action string will be ignored. The
menu item ID is case-insensitive.
Example: $Istatus_list& means entering the Status menu.
Note: To view the menu item ID, you can set “edk.id_mode.enable” to 1
(Enabled) and then long press the Volume Up key when the phone is idle.
$P<label>&T<title>&C<characters
number allowed>&N&M$
The string of the user input promt.
“label” means the specified label for the user input prompt.
"title" means the specified title for the user input prompt.
“characters number allowed” defines the maximum number of input char-
acters.
If &N is included, the character type is Number (default input method: 123). If
&N is not included, the character type is Text (default input method: abc), you
can manually change the input method. (For T57W/T48U/T48S/T48G, if &N is
included, the input mode is numeric&symbolic. If &N is not included, the
onscreen keyboard is displayed, you can manually change the input mode.)
If &M is included, the inputs are masked by the asterisk characters “*” (dot for
T57W/T48U/T48S/T48G).
