Temporary table within a package

Question

I'm not sure this is the best way to achieve it, but I'm trying to use a temporary table within my package, but I failed!
In my package, my procedure do receive 5 different phone numbers (vTel1 to vTel5) and I need to order them, using data from a table. Also, if 2 of them are the same, I need only the one with the highest rank.
Let say my TelOrder table look likes:
Reason
Tel1
Tel2
Tel3
Tel4
Tel5
Reason1
2
3
1
5
4
Reason2
1
2
null
3
4
And I receive those variable
vTel1='5141111111'
vTel2=null
vTel3='5143333333'
vTel4='5141111111'
vTel5='5145555555'
vReason='Reason1'
Using the Reason1, I need to be able to get the result looking like:
RowNum
Phone
Order
1
5143333333
1
2
5141111111
2
3
5145555555
4
And I need this code to be apart from the procedure, cause many procedures will use the same code, and I don't want to abuse the ctrl+c, ctrl+v at each update.
I've come close by using something like:
EXECUTE IMMEDIATE '
     INSERT INTO Table
     SELECT Rownum as RN, Ordre, contact_info, Contact_info_type
     FROM
       (SELECT a.contact_info, a.ordre, contact_info_type FROM
         (SELECT contact_info,min(ordre) as Ordre FROM
           (SELECT Tel1 as Ordre, ''' || vTel1 || ''' as contact_info, 1 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
           UNION ALL
           SELECT Tel2 as Ordre, ''' || vTel2 || ''' as contact_info, 2 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
           UNION ALL
           SELECT Tel3 as Ordre, ''' || vTel3 || ''' as contact_info, 4 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
           UNION ALL
           SELECT Tel4 as Ordre, ''' || vTel4 || ''' as contact_info, 4 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
           UNION ALL
           SELECT Tel5 as Ordre, ''' || vTel5 || ''' as contact_info, 1 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
         WHERE Ordre is not null and contact_info is not null
         GROUP BY contact_info
         ) a
       JOIN
         (SELECT Tel1 as Ordre, ''' || vTel1 || ''' as contact_info, 1 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
         UNION ALL
         SELECT Tel2 as Ordre, ''' || vTel2 || ''' as contact_info, 2 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
         UNION ALL
         SELECT Tel3 as Ordre, ''' || vTel3 || ''' as contact_info, 4 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
         UNION ALL
         SELECT Tel4 as Ordre, ''' || vTel4 || ''' as contact_info, 4 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
         UNION ALL
         SELECT Tel5 as Ordre, ''' || vTel5 || ''' as contact_info, 1 as contact_info_type FROM TelOrder WHERE Reason=''' || vReason || '''
         ) b ON a.contact_info=b.contact_info AND a.ordre=b.ordre
       ORDER BY a.Ordre
But when I try to remove this code and send it into another procedure/function, I can't make it work.
PLEASE HELP!!!!

No Database to try it. Check at your own risk if this might work for you
no version specified from your side, NOT TESTED from my side, so let's say we're even
select row_number() over (order by the_order) "RowNum",
       the_val "Phone",
       the_order "Order"
  from (select v.the_val,t.the_order,
               row_number() over (partition by v.the_val order by t.the_order) rn
          from (select reason,the_order,the_phone
                  from (select reason,tel1,tel2,tel3,tel4,tel5
                          from telorder
                         where reason = :the_reason
                unpivot include nulls (the_order for the_phone in (tel1 as 'tel1',
                                                                   tel2 as 'tel2',
                                                                   tel3 as 'tel3',
                                                                   tel4 as 'tel4',
                                                                   tel5 as 'tel5'
               ) t,
               (select 'tel1' the_var,:v_tel1 the_val from dual union all
                select 'tel2' the_var,:v_tel2 the_val from dual union all
                select 'tel3' the_var,:v_tel3 the_val from dual union all
                select 'tel4' the_var,:v_tel4 the_val from dual union all
                select 'tel5' the_var,:v_tel5 the_val from dual
               ) v
         where t.reason = :v_reason
           and t.the_phone = v.the_var
where rn = 1
   and the_val is not null
