i got a call from this number. i am an RN and had recently been applying online for positions.  they didn't leave a voice mail, which they will ALL do.  i have an iphone which told me the call was from Phoenix, AZ.  I googled it to find out if it was from a business, but i stumbled upon this post.  I will keep my eyes out, but it sounds fishy!!!

a person identifying himself as ray rodriguez from arizona called my cell phone number to inquire about a nursing position. When I repeatedly asked him to identify which company he was with, he refused to answer my question, and hung up on me. Usually a nursing travel company will at least identify themselves, and who is calling, where they obtained my phone number, etc....
this was very odd....and seemed like he was not being fully forthcoming.
