[noob] Multiple VM mailboxes - multiple languages?

Greetings, everyone,

Here’s a question i can’t seem to figure out by myself, still being an asterisk-rookie:

I operate a FreePBX 14.

There are three language packs available in my setup, as well as three trunks, covering three different countries (UK, US, DE). I would like to pass missed incoming calls on UK trunk into a VM with UK voice prompts, as well as missed calls on German trunk to be routed into a VM with German voice prompts, etc.

I figured out how to route calls from different trunks to different voicemail boxes, but I can’t make those mailboxes have separate language settings… (VM1 = UK, VM2 = US, VM3 = DE).

Your help in this regard would be highly appreciated.

Thanks in advance,
