Who called from 9044833340

I have found calls on my caller ID from R Martinez from 904-483-3340 and 3351.  Cannot return the call.  I just get the code NSCJX.

I receive calls from (904) 483-3340 and (904) 483-3342 I was able to pick up once, a man said "sorry" and hung up.  When I try to call back cannot connect.

I received a call at 9:30 a.m. Saturday morning.  I am in different area code.  When I answered the caller hung up or disconnected.

Found 904-483-3312 on my ID.  I get NSCJX on an automated message.  I'm not picking it up, but this number has been calling me repeatedly for over a week.  I'm reporting it to the DO Not Call Registry.

I received a call from the same number and picked up but whoever it was hung up.  When I tried to dial the number got a recording that I was calling from a blocked phone or that the number was unreachable.  I was not calling from a blocked phone.  The recording ended with NSCJX  (National Security Council??)

Was venting about the government and Bush last night on the phone with a friend........it's creepy that things are so bad that I can even contemplate that this may be something to do with our gov't. wiretapping program.  It's probably not, but I hate that I even have to wonder.
