The account's phone numbers, and the countries more can be bought in with today's prices. Calls go out from a number in the callee's country when the account holds one. US, Canadian and European businesses can always be called (Europe from a European number if the account has one, else from its US number), and UAE and Japanese businesses too, from the account's US number (the business sees a US caller ID); elsewhere, a number in the country is what lets the account call there. Numbers cost exactly what the carrier charges: the upfront cost plus the first month when bought, then the monthly cost every 30 days, taken from the balance. own_numbers are the user's own phone numbers verified with call4me_verify_number: free, and used only when call4me_place_call names one in from.
