Display Language

Allows user to choose preferred display language in web UI and key pad UI Currently, the phone supports these languages: English, Simplified Chinese, Traditional Chinese, Korean, Japanese, Italian, Spanish, French, German, Portuguese, Russian, Croatian, Hungarian, Polish, Slovenian, Arabic, Hebrew and Dutch.

Note: The “Automatic” setting in language refers to Grandstream’s IP2Location client which when connected to Internet would attempt to lookup a database (driven by Grandstream) with the IP address for its geographical location.

Language file postfix allows the language file to have different postfixes so the phone can request a particular file. It will append an underscore "_" plus the string in the language file postfix.

The default language file name is "gxp.txt". If the field “Language File postfix “has "NL" string in it, then the phone will request "gxp_NL.txt" instead of "gxp.txt".

User can only load one secondary language.

Supported downloadable language: Czech, Dutch, Estonian, French, German, Italian, Polish, Portuguese, Slovak, Slovenian and Spanish.
