Yes you could certenly do that. If one of your sip providers goes down 
and you have qualify=yes for them then the call should fail immediatly 
and you can detect the return code and automatically fail over to a 
different provider.

A better way would be to make use of AGI and write code to lookup calls 
costs for the specific destination so you can perform least cost routing 
between your providers. When the call is hungup you can record stats 
about that provider such as if the call failed.
