There are several possibilities on how to define 'active'. You could send 
OPTIONS like you suggested or you could try to setup actual calls over some 
test numbers with sipp or sipsak. Then you could insert the state in a DB, or 
use some FIFO commands (e.g. with cr) do change the routing. You could 
implement this with some small python or bash scripts.

But if you go for the OPTIONS path, then the easiest way would be to just use 
the dispatcher module, which already does this checking for you.
