Does anyone know how to find out the phone number a connection to my site is being made from? I need to confirm that a person logging in is physically where they are meant to be. Alternatively has anyone implemented a dial back system in php?

Nope, I'm pretty sure its impossible to find the phone number someone's calling from. Some users don't even connect via phone lines, they have cable modems, T1/3 lines etc. which don't have phone numbers. I don't think the internet supports something like this, let alone PHP. I know that ISP's can check to see the phone number of people dialing into their servers, if that's any use....

Can you use the IP address instead? for most dialups it's dynamic, each user is assigned somethign different each time the dial in. but usually the first 2 or 3 blocks of numbers are the same for a given ISP.
maybe this could be of use??

Thanks - I've come to the conclusion that asking the ISP is going to be the only way. Can't use IP as its the physical location of the person when they dial in that we need. I suppose I should be looking at GPS but its a bit expensive!
