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 and Slovenian.

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.

How to set up Download Language:

This is similar to updating firmware in your local network environment.

1.Get the language file gxp.txt ready. Make sure the file is using UTF-8 encoding.

2.Copy gxp.txt to the firmware server directory using your local TFTP or HTTP server.

3.Access the advanced settings of the Web GUI, set “Display Language” to “Download Language” and enter the server path in Firmware Server Path. Select TFTP or HTTP for firmware upgrade.

4.Update and reboot the phone.

GXP21xx has up to six line appearances, each with an independent SIP account. Each SIP account requires its own configuration page. Their configurations are identical.
