If you have installed the Address module, you will able to see Address field type while adding a new field.

So once you installed this module you will able to see a new field type called Address with Phone number. So if you need the phone number in your address container you can use this field type else use Address field type.

It doesn't add phone number into Address field type for that you can use normal phone number field.
