[Freeswitch-users] State of originated call

Hi, using javascript, i do originate the call this way: Session s= new Session(originateStr);

From this point, is it possible to know what states the call is going through? In a previous message it was suggested that variable_originate_disposition would give me the response code. Now, how to i use this in practice in a script? How do i for instance retrieve a 180 response code when rining is hapening on the remote end?

Thanks, Max.
