there is no need for this - there is a pseudo-variable returning the 
number of active calls:
       http://openser.org/docs/modules/1.1.x/dialog.html#AEN165

that's true; but the module implements a dialog timeout. Even if on 
short periods the hanged calls will be counted as active, on longer term 
they will be terminated.
