asterisk users - Aug 2009 - Detecting Called party Ring indication (and act on it)

is there a way to have asterisk short circuit the dial timeout  
parameter based on called party sending ring progress ?

History:  I have multiple routes that a call can take.  Some routes  
are not so good and take a long time.

Currently I use the Dial time out parameter, but it times out whether  
or not the called party is ringing or not (basically has to answer)
I think the term is PDD (Post Dial Delay)? I wish to move on to the  
next route if the progress is longer than X sec, but if I get  
indication of ringing then stay on that route.

Thanks
