Maybe NOT TESTED! No Database at hand just a guess
with
relevant_calls as
(select id,calling_no,called_no,calldate,calltime,duration,calltype
   from call
  where calling_no in (:number_1,:number_2)
     or called_no in (:number_1,:number_2)
select 'INTERNAL' kind_of,calling_no,called_no,calldate,calltime,duration,calltype
  from relevant_calls x,
       relevant_calls y
where (x.calling_no = y.called_no or y.calling_no = x.called_no)
   and x.calling_no != y.calling_no
   and x.called_no != y.called_no
union all
select 'COMMON' kind_of,calling_no,called_no,calldate,calltime,duration,calltype
  from relevant_calls
where called_no in (select called_no -- was called by both :number_1 and :number_2
                       from relevant_calls
                      where calling_no in (:number_1,:number_2)
                        and called_no not in (:number_1,:number_2)
                      group by called_no
                      having count(distinct calling_no) = 2
                     union all
                     select called_no -- was called by :number_1 and called :number_2
                       from relevant_calls x
                      where called_no not in (:number_1,:number_2)
                        and calling_no = :number_1
                        and exists(select null
                                     from relevant_calls
