Regular Expression creation for phone number

Question

I'm trying to write a single regular expression to validate phone numbers. Below numbers should be

1111111111 or 111-111-1111 or 111.111.1111 - should fail and at the same time 767-789-9876 or 7677899876 should pass

I have come up with ^(?!([0-9])\1{2}[^d]\1{3}[^d]\1{4}$), but it only helps validate repetitive digits, alphanumeric characters and all succeed. Can anyone help me improve my regex?

This has been answered before, see http://stackoverflow.com/questions/123559/a-comprehensive-regex-for-phone-number-validation — Alex, Mar 26 '15 at 17:25
I already checked that it does not help validate repetitive scenario — Christine Dsouza, Mar 26 '15 at 17:37

based on your examples, use this pattern

^(?!(\d)([.-]?\1)+$)(\d{3}[-.]?\d{3}[-.]?\d{4})
