Phones - Can the Sangoma Phone display in languages other than English?

Yes, several language/locales are available, including Spanish, Italian, French, German, Portuguese, and Dutch.

In version 1.3, In addition to language/locale setting, localization may also include changing the time format. By default, the Sangoma Phone displays in English/United States and uses a 12-hour time format. When you change to another language/locale, the Phone changes the time format to the appropriate time format and these tones: busy, dial tone, call-waiting beep, congestion (fast busy), and ringback are specified by country code. By default, the Phone uses the country portion of the locale to determine this.

This can be overridden in the config.xml by adding a tone_country setting.

There is currently no way to do this in the Phone's UI.
