        <br>
        this is exactly what im trying to achieve, i want to be able to
        check if called party is busy on another call then generate a
        different ringback than the normal one i use if not busy. Can u
        kindly provide a dialplan example coz im getting confused on how
        to track if the ext is busy as well as increment and decrement
        the limit value?<br>
