[cisco-nas] ISDN Authentication using Caller ID

[Gaurav Sabharwal]

I am trying to setup something described at 
http://www.cisco.com/en/US/customer/tech/tk801/tk379/technologies_configuration_example09186a00800949ee.shtml

To extend beyond, I would like to authenticate the dialin clients 
against the Calling-Station-ID RADIUS attribute and assign them IP 
addresses from a dynamic pool. This is on a Cisco 2811 router.

Can somebody please tell me if this is possible and provide me with a 
sample configuration?

Thanks,
- Gaurav
