Narrative:

I was acting as PIC for an instrument student. We had filed an IFR flight plan from ontario to payet V-4 boi. Ontario is an uncontrolled airport with an NDB approach. We were not able to contact salt lake center on the ground. We departed south and tanned and flew east in VFR conditions contacting salt lake center, who said they would not be able to activate our IFR clearance until 05. He said he had an aircraft 6 mi south on approach for the ontario airport. We proceeded east, VFR, climbing to 5000' VFR. The tops in the area were slightly above 4000'. We heard the aircraft who was cleared for the approach make a radio transmission on salt lake center frequency. We never did hear slc clear him for an approach, so he must have been clrd before we came on frequency. The other aircraft had not changed over to advisory frequency 122.8 ontario unicom after being cleared for approach. The other aircraft filed a complaint that we were flying IFR in airspace assigned to him for approach. We were 6-7 mi east of the airport at the time of the incident and maintained VFR conditions. The student instrument pilot was under the hood during the climb and departure.
