the matching is triggered by execution of Route processing callbacks 
that happen only by calling loose_route().

The dialog module registers a function to be called when the Route 
header is processed. In this function the dialog module does the 
matching algorithm. To get independent of that, for matching mode 2, a 
function should be exported by dialog for explicit call in the script, 
something like:

if(dialog_match())
{
....
}

Cheers,
Daniel
