Automating billing for international usage

[AnyWho]

Is there now an automated solution for billing international usage? Or at least an API? If not, when can one be expected? Looking at each account one by one and manually adding up the usage and entering it into the billing software is just not practical if a reseller has more than a handful of accounts with international usage.

As things stand now, can the call data be exported to a billing package that will parse it and charge each each account?
