Mobile phone authentication

[sean]

 Hi,

If I understand you properly you are trying to authenticate users by
their mobile phone number.If that's right you need Kannel. You can
download the latest version from http://www.kannel.org There is a bit of
a learning curve but once you have authenticated the user you can pass
them off to your Radius billing system. I presume that the
authentication will arrive via SMS, WAP or HTTP if it's 3G.

I hope this helps. If you need more advice you can email me at
sean at topup.ie

Sean
