Hi!
I am working on an application that will run within an ISP network and is meant to redirect users to specific servers based on their phone prefix. I have some questions to ask for anyone who has knowledge of how information flows within the network.
As I understand it, when a user connects to the internet either via a DSL or dial-up modem, data travels through the telecommunication infrastructure that the ISP uses to one of many available RAS routers that are responsible for the communication with an available NAS at the ISP. The Network Access Server will then pass the username/password to a RADIUS server that in turn will check that the information is correct using some authentication scheme. If accepted, the server will then authorize access to the ISP system and select an IP address, L2TP parameters, etc. for the user.
My question is:
Does the ISP at any point during this process know the phone number from which the user dialed up for the connection? Does this sort of information that can identify a user’s location (ie phone prefix) reach the RADIUS server?
If anyone could help me out with this it would be greatly appreciated.
Thanks in advance.
Alex.
