The best way to do a report on outgoing internatiional calls would be to use one of the Flexible report options and set the Number / Prefix to the digit patter that identifies an international call. For example from North America most international calls begin with 011 so set the number Prefix option to 011*. For calls originating from outside North America most international calls begin with 00 so se the number prefix option to 00*. Please note, if your phone system includes access codes in front of the digits dialed you will need to insert these at the front of the Number Prefix specified above. If you are unsure of what to enter, look at the Live -> View -> Calls option and locate an international call. Whatever digits appear infront of the 011 or the 00 in the Number field are the access codes.
