If you have had no prior contact with this number and it's calling you, then they are doing a cold-call. It could be someone spoofing a number to appear legit.
I ordered a catalog about Mississppi River cruses. I received it from American Cruise Lines. The call I got from this number was a followup call to see if I had any questions. They did leave a message, but I didn't the message before I started writing this. It appears to be legit.
