Please post the test data that you might be using with that code above, thanks.

Here is how to normalize a phone number.

@Kaufmed:
I do not know where to add this line you suggested:
$phone_pattern = '/(?:\d\D*){10}/';

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You said, "how to change the pattern..." I assumed by that you meant change this line:

$phone_pattern = '/([0-9]{0,1})?[-.\s]?(\(?([0-9]{3})\)?[-.\s]?)?([0-9]{3})[-.\s]+([0-9]{4})([\s]?[x|ext]?[\s]?([0-9]+))?/s';

two 345678901: Equals what, exactly?  Is this a commonly expected client input?

Anyway, thanks for the points, ~Ray
