Thanks, last thing I wanted to do was trawl through another long winded Ofcom document.
I notice that it says (emphasis mine):
"The Communications Provider shall ensure, where technically and
economically feasible, that End-Users in any part of the European Community are able to:
(a) access and use those Non-geographic Numbers which the Communications Provider Adopts;
(b) access all Telephone Numbers provided in the European Community, regardless of the technological devices used by the operator, including those in the National Telephone Numbering Plan, those from the European Telephone Numbering Space (ETNS) and Universal International Freephone Numbers (UIFN)."
They might argue that providing access to such numbers/services is not economically feasible? (Though I would then argue, they should have sensible tariffs).
It's also interesting to note that all providers should be allowing access to all numbers in the European Community. This is absolutely and definitely not the case in reality for every provider I can think of. They all bar some non geo ranges in other EC countries, they also bar some fixed and mobile networks where the termination rate differs from that of the main networks.
