Customizing the Keypad Input Method File
When adding new characters for the existing input method, ensure that the added characters are supported by the
phones. The IP phone can only recognize the keypad input method files uploaded using Unicode encoding.
1.
Open the desired keypad input method file (for example, ime.txt).
2.
Under the input method field (for example, [abc]), add new characters or adjust the order of the characters within
the double quotation marks on the right of the equal sign.
3.
Save the keypad input method file.
4.
Rename the input method file (for example, custom_ime.txt), and place it to the provisioning server.
Note: If you just want to customize the input method for a certain language, the file name must be “language name_ime.txt”
(for example, German_ime.txt). The valid language names are: English, Chinese_S, Chinese_T, French_CA, French, Ger-
man, Italian, Polish, Portuguese, Portuguese_LA, Spanish, Spanish_LA, Turkish and Russian.
Onscreen Keyboard Input Method File Customization
The T57W/T48U/T48S/T48G phones support using the onscreen keyboard to enter data and provide English
onscreen keyboard by default. You can create a new language onscreen keyboard or customize the existing input
method files of the onscreen keyboard.
Yealink provides three types of input method files for onscreen keyboard customization. You can configure them as
required.
You can ask the distributor or Yealink FAE for onscreen keyboard input method files. You can also obtain the
onscreen keyboard input method files online: http://sup-
