With that, do you mean the number without international prefix? That's
odd.
What's the provider you are calling here in uk?
I regular get calls from Germany with the correct international callerid
showing.

I don't receive any callerid from some (cheaper) german telco providers
(but most work correctly)
I vaguely remember that there are some pretty dodgy contractual
agreements lingering around. You might want to google for 'europe
callerid', specificially [1].
Are you sure your calls goes straight from Germany to UK? I found that
many German telecom providers terminate through the US, particularly to
landlines.

Maybe you could route your call to via sip to a uk voip provider and
persuade them to set the callerid to whatever you have in Germany? or
simply get a UK number routed via sip ? ;)
