UK Phone provider dialling codes

[oliverm]

Does anyone know where I can get a list of UK phone provider dialling codes? That is, I have a list of tariffs from our SIP provider (O2 = x.xp, Voda = x.yp etc). It doesnt tell me however which dialling codes they consider to be for O2, Voda etc.

However I need to tell 3cx what dialling code is used for O2 calls, which for Voda, T-mobile etc.

Does anyone know where I can get this list?

Ofcom has all of the prefix assignments available for download...http://www.ofcom.org.uk/static/numbering/index.htm

Don't forget that with number potability, you can no longer assume that a particular prefix is linked to a particular provider. If you take your T-Mobile number to O2 and someone calls you, they now pay the rate to call an O2 user.

Yeah, that occurred to me as i posted the question

I'll just average out the costs.

Thanks
