When setting up outbound rules, don't think about what you want to block, think about what you want to allow. All else will be blocked. You can base the rules on the number of digits and/or digits dialled.
How are local or national calls dialled as opposed to international calls (the ones you want to block)?
If there was one particular prefix that you wanted to block, like the 01900, you could create a rule that went off to a trunk group with no members (dummy group). It is also possible to send the caller to a recording, but getting nowhere a few times should give them the idea that they will not get through and not to bother trying again.
