list values ​that are duplicated more than 4 times

I am making a join between 2 tables, where they bring me number_phone that have a relationship and I bring the times that these are repeated, however, I am trying to make a condition to the count, so that it only lists those that are repeated more than 4 times, I tried with having account and it brings me the counter all in null. It is worth mentioning that I did not occupy group by for the count because it brought me wrong values.

SELECT
    REPLACE(REPLACE(t.id_contrato,'0999',''),'0998','')as contrato , 
    t.num_telefono,
    conc.valor_actual,
    (
        SELECT COUNT('x') 
        FROM TBL_TELEFONO ct 
        WHERE ct.num_telefono = t.num_telefono
        AND ct.origen_tel='TELEFONO CONTRATO' 
        -- HAVING COUNT(*) > 4 
    ) as counter 
FROM TBL_TELEFONO t
INNER JOIN  CAM_TBL_ALERTA_CONCENTRADO conc ON t.num_telefono = conc.valor_actual 
WHERE id_contrato IS NOT NULL
AND id_contrato NOT IN ('N/A')
ORDER BY 4 DESC

How can I list only those that are repeated more than 4 times?
