Few years ago all the mobile companies started charging for 0800 calls, when
in fact they get PAID by the 0800 number owner to deliver the call.
This was in response to various competitors offering cheap(er) calls via an
0800 number (e.g. OneTel).
If someone is willing to take 0800 call from a mobile and forward it to
Timbuktu is none of the business of the mobile provider !
Clearly this IS restrictive and highly anti-completive action from the
mobile providers !
Complaints were sent to Oftel, but nothing was ever done about it !
So, for the same reason, they will get away with blocking VoIP calls....,
(until maybe Ms Viviane Reading at the EU decides to force them)
