No.  Dial either goes to the next priority when the Dial command times 
out or current priority+101 if the call did not connect for any other 
reason.  If you want more complex handleing of this than you need a much 
more complicated dial plan.  For example the [macro-std-exten] in the 
extensions.conf.sample.

This has been talked about over and over and over in the mailing list 
archives.
