Regular expression phone numbers

Hi guys i need some help for a regular expression to validate phone numbers.

thank you in advanced

valid input:

+31 (0)70-1234567


+31 (0)701-123456


+31 (0)6-12345678


Is it line break after +31 (0)70-1234567 and the number continuing, or it is an 2nd variant of the correct number ?

these are all valid inputs. it’s only possible to enter one phone number at the time.
