You might want to review the documentation on window specifications (which is here). The default is "range between" which defines the range by the values in the row. You want "rows between":

select grandtotal,
       sum(grandtotal) over (order by agentname rows between unbounded preceding and current row)
from call;

Alternatively, you could include an id column in the sort to guarantee uniqueness and not have to deal with the issue of equal key values.
