 Add an interface check for the dialup interface but negate the result. 
 If the interface is down everything is OK. But if the interface is up 
 then you should set the status to CRITICAL or WARNING.

 You will need to add some effort of your own into this but this would 
 be roughly how I would add monitoring. Just considere the backup link as 
 a service of each router and set it to CRITICAL if the dialup interface 
 is up.
