Can someone shed some light on how you might be accomplishing this, I have a hard time believing that customers are being told they cannot dial TF numbers in their own country.
In the US, it's always been my understanding that what we call INWATS calls are dipped *at the originating CO*, and the actual toll call across the SS7/TDM backbone goes out using either the real 10D DN of the target line, or some fake 10D that routes to the appropriate trunk group somehow at the destination end. So it's not that unusual to me that a network that is interfacing at Class 4, instead of Class 5, might be unable to originate calls to TF DNs. I admit to not being sure this is a worldwide view of the issue, as our Wikipedian friends would say, though. Cheers, -- jra -- Jay R.

I was under the impression that the dip returns the IXC that handles the number, and the call goes out with the original number for the IXC to handle. The translation to POTS or whatever happens at the IXC's SCP. The SCP could reject the call if there's no route that matches the condition on the incoming call. ("The number you are calling is not available from your area") There's a lot of 8xx processing that routes based on time of day or where the caller is or whichever call center is less busy. That would seem hard to do if the 8xx number were already translated. The originating CO often does the dip to get the 10D target for LNP, but that's different. Could someone who understands this better clarify?
