Snoopy points out that the ringing voltage on a phone line exceeds 50 volts,
and therefore telephone wiring ought to be class 1.

I checked with a local expert on such matters and he informs me that telephone
wiring is indeed class 2, probably because of the strict current limiting
(20 ma) that is applied to the ringing current.
