Cisco 1811 V.92 Dialup to ISP

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.

Is that link for configurung dial out?  And will this require chat scripts?
RSLE

it's for both dial-in and dial-out

as for chat scripts, I doubt it unless your ISP has some odd setup.  If a normal pc dialer works without a special chat script you should be ok.

RSLF, Your post got me most of the way there, I had to add a couple of thigs to make it work.

I had to set this so that the router would authenticate to the ISP 1 way:
ppp authentication chap callin

and instead of ip unnumbered I had to use: ip address negotiated

Now I am able to use IP SLA and route maps to automatically failover to the dial up if the DSL or the Rtr interface go down.  
Tested and working...
