^(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:\(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*\)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})(?:\s*(?:#|x\.?|ext\.?|extension)\s*(\d+))?$

is not working many of above

^\+?(\d[.\- ]*){9,14}(e?xt?\d{1,5})?$

explanation;

^ asserts start of string \+? matches optional plus (\d[.\- ]*){9,14} between 9 , 14 single digits, perchance seperated spaces, dots, or dashes. (e?xt?\d{1,5})? optionally x perchance preceeded e or followed t. letters followed between 1 , 5 numbers. $ asserts end of string
