Find phone numbers with unneeded characters

Hi, our system allows users to enter extra characters when inserting or altering phone numbers in our database. This has led to phone numbers to be saved with comments, spaces, etc. The saved phone number should contain 10 numeric characters. I need to run a query to find all records that do not follow this pattern.

Thank you.
