It's opt in. In a radio segment the other day they said 6k people have volunteered. Which makes it very much non-random, but still, cute concept.

probably a good thing, you wouldn't want most of the calls to be answered by people very unhappy to be cold-called by some random foreigner...

The fact that they are volunteers doesn't change the fact that it's random, it just changes the set from which the random values are selected.
