The caller was from a collection agency called F.C.I.. (First Collection Inc)  Now if this was a spoof number that this company use, or if it was one of their employee's or if it belongs to the company its self I don't know.  What I do know is that this collection agency will go to great lengths and is listed as one of the worse companies to deal with.  Funny thing is, they'll go after you even after the statue of limitation is up, or after you filed bankruptcy and this debt was listed.  In short you cannot trust them
