asterisk users - Aug 2017 - asterisk13: no voicemail prompt in German

According to the instructions given at 

https://www.asterisksounds.org/de

I converted and installed German prompts successfully and for numbers, I can
successfully
listen to a German female voice counting or telling the date/time.

But unlikily, somehow the voicemail prompt is still English, although my general
language
settings are "de".

I use pjsip.conf, not sip.conf.
In asterisk.conf, there is the follwoing defined:

[options]
[...]
defaultlanguage=	de_DE

In extensions.conf,

I use:

[general]
format=		gsm
[...]

and for the inbound endpoint:

[inbound]
exten   =>      THENUMBER,1,SetGlobalVar(CHANNEL(tonezone)=de)
same    =>      n,SetGlobalVar(CHANNEL(language)=de_DE)
same    =>      n,Set(DIALGROUP(group_isp2,add) = PJSIP/502)
same    =>      n,Set(DIALGROUP(group_isp2,add) = PJSIP/512)
same    =>      n,Dial(${DIALGROUP(group_isp2)},30)
same    =>      n,VoiceMail(502 at my-vmmbox)
same    =>      n,Hangup()


and in voicemail.conf I have

[general]
[...]
tz=             german  ; Timezone from zonemessages below. Irrelevant if
envelope=no.
locale=         de_DE.UTF-8     ; set the locale for generation of the date/time
strings
(make ; sure the locales are installed in your operating system; e.g
german=                 Europe/Berlin|'vm-received' a d b Y
'digits/at' kN


So far.

In asterisk.conf, the directory for sounds data points to

/pool/asterisk/share/asterisk/sounds

which is comprised of 

./en/
./de_DE/

de_DE contails all the .sln16 and .gsm files, owned by asterisk:asterisk, from
the source
above. Since the prompting of numbers and the date works well, but not the
voicemail
prompt, there is something fishy I can not fathom.

For your help I'd like to thank in advance,

Oliver

Are you sure this should no be simply "de_DE"?

Not sure, but according to the documents, this referes to encoding and needs to
meet base
system's locales, so it doesn't have to do anything with the delegation
of the correct
prompting in the proper language, I guess.
