New to the middle east- take this for what it's worth (from a ME controller).
Please check in with your level and squawk.
On first contact, you will probably be given a route clearance. Don't let this be a surprise to you. Fly the CLEARANCE, and if it differs from your flightplan (or the FMS), query it.
Don't say "confirm?" at the end of readbacks.
Enjoy your expanded horizons!
