If you have caller ID on your landline telephone, it is going to display all of the contact person's information, especially if the call is being placed from another landline. However, when using a cell phone, the number of the line is the only information displayed. If you are curious as to the actual address of the landline calling you there is a way to find the address, simply off the given phone number.

Type in the complete number in the "Reverse Phone Number" bar and click "Find."
