stop voicemail | Technical service details | Consumer forum

I bought a Nokia-set and put the sim-card in my (quad-band) Motorolla KZR 1 from Germany, which works fine. I didn't want to initialize the voice mail, to not have to retrieve messages from there; so now people tell me, that after 3 ring tones a message comes "voice mailbox not initialized" - and I didn't catch any ring tone, just the beep for "missed call". I tried to get through the settings menu, but nothing allows to put the voice mailbox to 6 ring tones or so. When I try to change "redirection" (to the mailbox) to "out" it comes a message "trial failed", so it's always directed to the mailbox.
Is there any way to handle it to get rid of the mailbox-involvement ?
