How to play songs over a iphone call for both parties in call?

Yes, my online research experience has failed me. As i can't seem to find the solution for this question.

Everytime someone calls me, it comes up as unknown?

I have an iphone 3gs, and EVERY TIME some one from my contacts calls me, their name doesn't come up, it just says "unknown".
I have had my friends try and call me (without their number blocked) and it just comes up "unknown".
How do i make it so it doesn't come up as unknown?

It's annoying because i always have to say "who is this?" and then they are like, "why don't you have my number?"
