this is a scam,not a texas exchange,but phones in america do not display the numbers for other countries in the proper format for them (14 30120-3569) with 14 being country code 30120 is city code and last four numbers 3569 being the phone number,if you call back can be charged for out of country call by your provider.
anytime a 1 or a + shows up in front of  number it should not be answered,not required or needed to dial a U.S. number
