In addition to communicating with the local air traffic control facility, aircraft are required to give the Iranian Air Defense Radar (military) a ten minute 'heads up' that they will be transiting Iranian airspace. 
This is a common procedure for commercial aircraft and involves giving them your call sign, transponder code, type aircraft, and points of origin and destination. 
  
I just flew with a guy who overheard this conversation on the VHF Guard (emergency) frequency 121.5 MHz while flying from Europe to Dubai . It's too good not to pass along.  The conversation went something like this... 
  
Air Defense Radar:  'Unknown aircraft at (location unknown), you are in Iranian airspace.  Identify yourself.' 
  
Aircraft:  'This is a United States aircraft.  I am in Iraqi airspace.' 
  
Air Defense Radar:  'You are in Iranian airspace.  If you do not depart our airspace we will launch interceptor aircraft!' 
Aircraft:  'This is a United States FA-18 fighter.  Send 'em up!' 
Air Defense Radar:  (no response ... total silence)
