Is ringing voltage dangerous?

The recurring spec that I keep seeing is 20 Hz at 90V.
I don't know whether that is peak to peak or RMS.
Most phones will respond to a wide range, and there are almost certainly
different specs used in different places.

Yes, it DOES bite.
In the right special cicumstances, it COULD kill, but death is unlikely.

Zapping your kid brother is NOT a good idea.
