There is no reason why you can't try. Don't expect them to give it you though.

Thanks for swift replies to you both.

Is there anything in law that requires them to disclose geographical numbers? Freedom of Information, all that sort of stuff?

Only public bodies come within the Freedom of Information Act so if it is, for example, your local council, an FOI is a good idea - worked for me with Essex County Council.  Some companies will give geo nos, some won't, but it is always worth a try (you might just get a disgruntled employee serving their notice who wants to help!)   If I have to deal with an organisation which only uses 084/087, I try to communicate via email which also has the advantage of a written record of exchanges (& could include a request for the geo no!)  As has been said, a threat of not giving them your business might work.   Good luck!

Demand away.

You'll have some 0844's which terminate at a SIP address. Even better if that SIP address is behind a NAT, giving you no luck with the latter.

Not all revenue sharing numbers have a simple geographic alternative. Whilst many may be routed to one or many accessible geographic numbers, even that is not necessarily the case.

The essential point at issue is that this is an organisation which charges you to speak to someone. Imagine a counter with a screen, where you have to put money in a meter to stop the screen coming down during the conversation, or at the end you are presented with a bill according to the duration of the conversation. (In some cases you even to pay whilst in a queue whilst waiting for someone to become available to speak with you).

There may be ways that some can use to bypass this process, i.e. alternative contact numbers or underlying geographic numbers. Some telcos give some of their subscribers a "free pass" in some cases by collecting the money from their customers in other ways.

All of this is just the mechanics, the essential issue is that a charge is being made for contact by telephone. I would suggest that this is the point that should be challenged.

He/she is saying that more modern systems can operate without underlying geographical numbers.

Indeed it is, pending the BT takeover this site relies on its ads.

Using the provided links I find that I can call 0845 630 88 88, to get a "Self Image Profile" and contact the NAT West Bank in Winchester on 0845 605 1605.

The friends in question are probably the authors of the Wikipedia articles on Session Initiation Protocol and Network Address Translation.

The articles about the SIP Scootershop and the National Aids Trust were also interesting.
