I checked my samsung setting. I cannot find any voicemail setup. Now, I doubt this is note8's problem.
Have you got another phone to test? I would try the SIM in another phone and see if voicemail notification come up.
Also, if possible, I would try to test another SIM in your note 8 and see the notification was there.
I would try to find if it was a phone or carrier issue.
