Received a call from this number.  No Message.  I called the number back, and it went straight to an automated voice message saying it was "The Benefits Call Center."  They were asking for information such as name, phone number, and employer.  

I was able to answer the phone quick enough to get a person on the line.  He asked who my employer was. (shouldn't they already know that)  I have him a false employer, and he said that he would direct my call then immediately hung up.
