I was with an instrument student in a P210 preparing to depart IFR from Leesburg, Virginia. The remote radio frequency wasn't operating, so instead we set up the frequency for the Ground Control Outlet and clicked the microphone to activate the autodial telephone patch to Dulles Approach for our clearance.
Dulles Approach (on radio via Ground Control Outlet):
"You have reached the Dulles air traffic control approach facility. No one is availahle at this time to answer your call. Please leave your name and number, and someone will call back as soon as possible."
What, they don't have caller ID?
