Calling them back, caller is a Las Vegas vacation site. Their cited website is under construction, but a google of vegas229 showed a previous site advertising Las Vegas packages for $229... presumably where they got the name.
I give up on complaining to FCC about these unwanted calls from telemarketers, even though I've been registered on the Do Not Call registry (what a joke). I simply don't answer my phone unless I know who is calling (noted on caller ID). I've noticed most telemarketers do not want to leave message on voicemail.
