Not sure about this... on my iphone, the call forwarding option is Not on... if i dont answer the call goes to voicemail (and its when i go listen to my voicemail i get dinged long distance minutes)
I think I have this same issue, where when I access my voicemail it dials an ON number (I am in NB). How do I make it not dial an ON number when I access my Voicemail?
