Yes, as part of the process of charging for calls made. But only for
calls answered, its not that simple with calls that didnt get answered.

is that the data is available the way you want it.

Yes. But they wont give that info to you. They may
well give the cops that info if say you get murdered etc.

Certainly doable and has been done when the cops request it etc.

Corse the detail varys with the country on access to the data.
