I can provision the phone - all values are set except language and localizing. I followed this guide: http://www.3cx.com/blog/ip-phone-configuration/cisco-display-language/ Firmware is the newest 7.5.6a and I've also tested with 7.5.5. Language has been set to Danish at the extension page. Language file is from SPA30x_SPA50x_SPA51x_SPA525G_7.5.6_Dicts.zip: spa50x_30x_dk_v756.xml and copied to: C:\ProgramData\3CX\Data\Http\Interface\provisioning\XXXXXXXXXX\firmware\cisco The log indicates no error. What am I missing?
