Permit to certain telephone numbers to dial-up to a RAS

yboul1234 — Wed, 29 Jun 2005 09:36:34 GMT

I want to set up a remote access server with one wic-2am and one wic-1b-s/t cards.

I would like to know if it is possible to configure the router to accept calls only from particular telephone numbers.

Thanks in advance

Hello,

for the ISDN connections, you could use the 'dialer caller' (or 'isdn caller' for legacy dialer profiles); not sure if something similar exists for analog connections...

Thanks a lot for the reply.

I would be grateful if anyone knew something similar for the analog connections as well...

No analog modem interface, on any Cisco router, provides any way to monitor or control on the basis of analog CLID. This includes the WIC-xAM.

If you want to do CLID screening on calls from analog modems, you'd need to have those calls come into a digital modem module (which would require using a digital interface into the circuit network, such as BRI or PRI.)
