Does anyone know if they get a bigger cut of the bigger fees charged
to mobiles for those numbers? *I've never understood the logic behind
that.
I think the 'termination fee' (that is, the fee paid to the final
telco, which in this instance it then shares with the called party) is
the same regardless of where the call originates from (so the rest is
kept by the mobile service provider) - so from a mobile users
perspective it's a mighty expensive way for TfL to collect a few
pennies for the call.

No. 0843 numbers are covered by the "NTS" regime. With these, the
originating operator gets to charge a fee which is fixed by Ofcom, and
then hands the rest over to the terminating operator. The size of the
originating fee depends on where the call is handed over (and,
therefore, how much of the originating operator's network is used).
There are extra charges if number portability or a transit network is
involved.

In essence the terminating operator buys "origination" as a service at a
controlled price.

BT buy and sell origination under schedule 211 of the SIA
http://www.btwholesale.com/pages/dow...port/contractu
al_information/docs/nsia/nsch211.rtf. For calls to BT, handover is to
be as close to the originating point as practical.

0843 222 isn't a BT range, but BT's termination fees for NTS services
can be seen at:

nformation/carrier_price_list_browsable/B1_06.xls
and
http://www.btwholesale.com/pages/dow...port/pricing_i
nformation/carrier_price_list_browsable/B1_06a.xls
In effect, BT are saying "we'll pay you an origination fee of what you
charge the customer minus this number".

Other terminating operators will have their own prices.

[Disclaimer: this hasn't been part of my job for two or three years now,
so I don't guarantee its accuracy.]
