It depends upon what each outgoing country operator wishes to try. Since they do not get paid for failed calls to unobtainable numbers some have found it easier to bar (at their end, rather than wait for a failed return signal) bar anything that is not 01, 02 or even 07. Of course, now that they can offer differential charging to 07X it depends upon their interconnect arrangements. But there is no central arbiter. I hope that this will help. And, of course, it is down to regulation not technical restriction or limitation...
