Oracle Regular Expression to match US Phone Number Format

Oracle Regular Expression To match US Phone Number in the following formats only.

(NNN) NNN-NNNN or NNN-NNN-NNNN or NNNNNNNNNN

I have tried and came up to this :

with test as
(
select '(444) 123-6780' as testcol from dual
union
select '444123-6780'                from dual
union
select '6741236780'                from dual
union
select '(445) 123-6781'            from dual
union
select '447-127-6787'            from dual
union
select '447-127-3333333333'            from dual
)
SELECT *
FROM test
WHERE REGEXP_LIKE(testcol, '^\(?\d{3}\)?([[:blank:]|-])?\d{3}-?\d{4}$');

Results : 

(444) 123-6780  -- valid
(445) 123-6781  -- valid
444123-6780     -- not valid
447-127-6787    -- valid
6741236780      -- valid

As you can see, I received 444123-6780 (NNNNNN-NNNN) format, which I don't require.

Is there any way to stop the above mentioned format not to match?

REGEXP_LIKE(testcol,'^(\(\d{3}\))([[:blank:]])\d{3}-\d{4}$|^\d{3}(-)\d{3}(-)\d{4}$|^\d{10}$')
