Description:
Configures the access URL of the custom keypad input method file.
Example:
gui_input_method.url = http://192.168.10.25/ime.txt
During the auto provisioning process, the IP phone connects to the provisioning server
“192.168.1.25”, and downloads the custom keypad input method file “ime.txt”.
gui_input_method.url = http://192.168.10.25/Russian_ime.txt
During the auto provisioning process, the IP phone connects to the provisioning server
“192.168.1.25”, and downloads the custom keypad input method file “Russian_ime.txt” for
Russian language.
Note: If you want to upload a custom keypad input method file for the desired language,
you can name the file “language name_ime.txt”.
When adding new characters for the existing input method, ensure that the added characters
are supported by IP phones.
The IP phones can only recognize the keypad input method files uploaded using Unicode
encoding.
Do not rename the keypad input method filename.
