Input Method
Keypad Input Method Customization
Keypad input method customization allows users to customize the existing input method on IP
phones. You can first customize the Yealink-supplied keypad input method file “ime.txt”,
“Russian_ime.txt” or “Hebrew_ime.txt”, and then download it to the IP phone. The changes in
the “Russian_ime.txt” file becomes affective when the language is set to Russian. The changes in
the “Hebrew_ime.txt” file becomes affective when the language is set to Hebrew. The changes
in the “ime.txt” file is affective for all the languages. IP phones support 6 input methods: 2aB,
abc, Abc, 123, ABC and Hebrew. By default, Hebrew input method is hidden, the IP phone will
automatically display the Hebrew input method when the language is set to Hebrew. If you
want to set the language to Hebrew, you have to add the new custom language - Hebrew to
your IP phone in advance. For more information, refer to Customizing a Language for Phone
User Interface on page 268.
If you just want to customize the input method for a certain language, the filename must be
formatted as “language name_ime.txt” (e.g., German_ime.txt).
You can ask the distributor or Yealink FAE for keypad input method file. You can also obtain the
keypad input method file online:

information on obtaining the keypad input method file, refer to Obtaining Boot
Files/Configuration Files/Resource Files on page 142.
