Mailing List Archive: dial-backup "extra" authentication

A lot of our customers have leased lines with us, but they also have an isdn line serving
as a backup method. The ll + bri config is on the same router on customer's side.

We are trying to find a method (through aaa) in order to distinguish isdn calls coming
from this router, from isdn calls coming from a pc. Both calls are made using the same
username/password and are terminated to the same nas.

Is there a way we can accomplish such a thing?

We're thinking of CLID, but there are 2 problems with this:

1. Our PTT doesn't always provide CLID
2. The pc isdn call may originate from the same isdn number as the router isdn call, so
the CLID will be the same

Realistically, I think your best bet will be to change
the username/password configured on the ISDN client routers
to be different from what's used on the PCs.

If you can't have different usernames, and can't count
on CLID, then all that remains is DNIS. Of course there
will be nothing stopping the ISDN PCs from calling to
the "router" DNIS, other than obscurity.
