Good evening, Matty1988! I would be curious as well if my calls were coming through on my landline. Let's work on this together. When did this issue start happening? Were any changes made to your iPhone 8? Have you ever setup call forwarding on your device? What happens if you dial *73 from your iPhone 8? This is a normal method for canceling call forwarding. Here is a link for assistance: http://spr.ly/6605Gy8yB . Please see #4 on this list. Please let us know if this helps at all. We look forward to hearing from you.
