The Australian operator called a US operator to do a "coin phone check" on the number billed. My impression was that this was a specific check not automatically done. In short, the trick of calling from a pay phone and billing third-number to another pay phone will work unless the operator does a coin check. The most likely route to apprehending the person using this trick would be to inquire of the person called whom they know in the area of the origin of the call. The closest it could come to airtight would be to call from a payphone to a payphone billed to a third payphone.
