I have received several calls from this number over the last several months from a man known to me as "Brian Jones".  I did not answer the first several calls, believing they were from someone on Robins AFB, GA who had just called the wrong number, until I answered and it was actually Brian Jones calling.  This number is a base telephone communications trunk line, and generally registers when a person receives a call from someone working on Robins AFB, GA.  My caller-id registered "RAFB DMAR"  I believe this man to be a scammer, with possible ties to terrorism, although he maintains his innocence.  He is located in Accra, Ghana.  The details of the calls that I know were him are:  8/2/2007, 4:41 am; 8/25/2007, 10:43 pm; 8/29/2007, 10:30 pm.  The Ghana cell phone, service provided by MTN (formerly Areeba prior 2 Aug 07), that he calls me from is 011-23-324-952-7500.  I do not know the actual billing name, although I doubt it is Brian Jones.  Another cell is 011-44-703-183-9268.  A fraud agency in London, UK told me that the fraudsters/terrorists use these UK forwarding services (011-44-7**) to fool their victims into believing they are in a country other than the one they actually are in.  His use of the 478-327-9999 telephone number has been reported to the FBI in the fraud report I filed with them on their IC3.gov website.  He has used other US numbers also to make his connection with me.  These numbers are typically numbers that are "no longer in service".  Also, various other cell numbers in Accra, Ghana will display from one minute to the next when he calls repeatedly.
