In my (not particularly recent) experience of flying from Turkish into Iranian airspace it can sometimes be difficult to raise Air Defence 10 minutes before the FIR boundary. However I was always able to raise the Tehran Radar airway controller who was always happy to relay to air defence. Just don’t arrive unannounced unless you want a welcome committee to intercept.
