Caller left an automated message saying that it was really important to call back about something.  Old guys voice.  Makes it sound like it's a buddy, but it's really just a collection agency trick.  Enjoyed the "talk to you in a minute" at the end of the call. Call back number is 913-541-9925, but this is KCI.  Sometimes they leave a name in the message, but I don't know who this person is.  If you have read about KCI before and just want to avoid a headache, I would suggest avoiding the call and not answering unknown 913 callers.
