Depending on country codes, country you're in etc. the format of a phone number can be very different, so using the regex /\(?\d{3}\)?[\s-]?\d{3}[\s-]?\d{4}/ is too restrictive. The model is detecting my phone number, but with confidence 0 (as opposed to everything else being -5) but is not parsing it. Is this a common regex used or is this particular parser too rigid?
