HI this is Umer

The correct answer is: He talked to me on the phone. We can also say: He talked to me by phone.

We can use 'over the phone' when we are thinking about the phone the means of communication when there are other possibilities:
They gave me an interview over the phone.
You can interview someone in a number o ways- phone, face-to-face, etc.
