I have a Cisco 1811 that is hooked up to a DSL line. I would like to hookup the V.92 modem to a POTS line and allow it to be a backup of the DSL goes down. I want it to dial up my ISP with my dialup account creds. I have never configured a router like this before, is it as easy as setting up the async1 interface to use a dialer interface that has all the dialer stuff setup on it already. Is there any good docuemntation on how to set this kind of stuff up? Any help on this one would be great.
