AFAIAA charging is almost always based on the original owner of the
header code. My number - 07909 - was originally Vodafone but is now on
Orange. Orange charge it as an Orange call but most others still charge
it as Vodafone.

The "enormous database" doesn't exist yet, hence the 'Atlantic Telecom
Problem':

http://www.ofcom.org.uk/consult/cond...umb_port_cons/

Although various operators seem to not want a sensible approach to number
portability:

No providers do this in the UK as yet, presumably citing some pathetic
excuse about "data protection".

Agreed.

Most mobile networks have one charge for on-net and another for
cross-net. They don't charge different rates for different networks.

That's more or less correct.

Unreliably informed. Ofcom requires nothing of the sort. The call would
be charged as a call to Vodafone from a fixed line network.

> This is what I believed *should* happen,


Nope. Fixed line operators (including VOIP) have no idea which network
the number is on, and can only chare by dialling code (the network that
issued the number) It has always been like that.

There are several. Each network maintains at least one. See
http://www.mobileshop.org/howitworks/databases.htm especially about NP
databases.

Eh? In the UK, CLID sends a number, not a name.

What name?

There is no other way, until this common database is established (if it
ever is)

Voicestick is not a UK mobile network. It is a VOIP operator, as far as
I know.

The CLID is also interconnected to the sip session ?
