UPDATE:
I called them back, got a automated voice system "Hello, this is a travel related call, please hang up and will we contact you shortly. If you'd like to be removed from this list press 1" I pressed one and they asked for my phone number, no way I'm giving them any more info, so at that point I hung up. Automated voice was in an English speaking female.
Got a call from this number - the caller left no message. I received a call from another seemingly bogus number last week. This is becoming a nuisance.
