Change display language on NT NS1000UK phones

[Pinmha]

On an NS1000UK system, there's no way to change the display language on NT phones, as selecting any of the five system languages always returns English.
Is there a way to install an additional language, such as Spanish?
Thank you very much.

For a while I received NS700/1000 UK version, to switch the phone displays to French I used this (included instructions and multi-language files)
(NS700 NE)

Thank you very much, it worked for me with the NS1000UK and I was able to install the additional languages Spanish, Catalan, German and French.
