dialup access and phone number

[yamahdi]

Hi all.

In a dialup connection to cisco router(or access routers):

If it is possible (for users dialed to router) to diagnostic the phone number of dialers (their's phone num.)?

Thanks alot.

I think you want to get the callerID of the dialin clients connected to Access Server right?

YES..you can get that using "sh caller ip" command on access servers. But for that you need to have a digital line like BRI, T1or E1/PRI, T1/CAS etc on the access server accepting dialin connections..and need to have telephone company sends callerID when calls are sent to Access Servers.

So as long as telephone compant (Telco) sends callerID to access server over digital line, access server can capture it.

Hi Tepal.

I got my answer. In an ISP some times the user's ID and Password may be hacked. I looked for away for understand where he/she(hacker) dialed to network.

Thanks in advance.
