My iPhone always shows unknown, any help?

Anytime anyone calls it always comes up with unknown, even with people i know that dont have there number blocked.the only time a number has ever come up within the past year is when i missed a call and got a text.im with optus so do i just have to call to change this or am i stuck with it? I've tried resetting my phone multiple time but still didn't work. Please help
