Disable voicemail or call forwarding

[Android Central Question]

Samsung S8 updated on 17 april - now got auto call forwarding to voicemail when busy etc. Tried to disable but says operator wont allow it? Can I disable voicemail feature altogether

To the best of my knowledge, there isn't anyway to completely disable voicemail on any mobile phone system.

Also almost all landlines have voicemail too.
