Rec'd a call from this number.  Caller was Asian with somewhat broken English and sounded to be reading from a script.  She said she was with "the travel office of Southwest Airlines" and wanted to invite me to an open house in their new Richardson office.  I asked her to confirm she was with Southwest Airlines and she said yes.  I told her I wouldn't be attending any open house and she said okay and hung up.  Did not pass the smell test.

I got an unsolicited call from this number. The lady spoke English with strong accent. She said something about being some kind of travel company. This is the second call I've gotten from this number. I have reported them to the DoNotCall registry.
