I saw this number on my caller ID.  I thought that since I was a member of AARP that this was some sort of sales call from a third party.  But when my 20's son got a call, I knoew it was a telemarketer.  I am lucky that I have call forwarding where I can forward the call back to them and I don't have to get these types of calls.  Senior benefits do have many numbers however and I will just forward them one at a time.
