feature request: show country in talk reporting, cant see where users call us from

Hello!

I recently enabled international outbound calls and I wanted to see which countries call us the most to calculate average of calls and the costs, however in the talk dashboard there is no way to see what country users call us from, so then I tried to create my own report in explore for this information,  but there is no way to do it there either

however, all phone numbers have country codes, so I imagine you guys could add that option to explore
