Enabline phone on contact page

[Getz]

I have added the phone option to enable customers to leave their phone number on the contact us page.
however they receive an error "number does not appear to be valid!"
it is possible that I have the incorrect Regular Expression Pattern:
can someone please assist with the Regular Expression Pattern or advise on how to set this up
thanks

How did you add the number? Can you post your Regular Expression Pattern?

Below regex example is for number with format 000-0000-0000

Code: [Select]

$phone = '000-0000-0000';

if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
  // $phone is valid
}
