I am using this in an if statement. It does check for valid phone number entry:
The problem is if someone enters 22- 234 2324 it doesnt check the "-". Please advise if anyone has a better phone number regular expression validation. Iam using this to verify a valid phone number entry on my form. 
/[^((\d\s?[\(\-\.\s]\s?)?\d{3}\s?[\)\-\.\s]?)?\s?\d{3}\s?[\.\-\s]?\s?\
+d{4}$]/
