Why do you think that calling cards might be an abuse?

Please note that 0800 numbers aren't really free, not even from a landline.
The recipient is charged for such calls. It is similar in principle to a
reverse charges call.

If you use a calling card then the service provider is reimbursed at
whatever rate they have negotiated for interchange fees, which strikes me as
a good market solution to abuse by the service provider. Indeed, it ought to
be a license condition that service providers may neither block any 0800
number nor make any charges to the caller.
