Wellll -- I do it on occasion. I generally pull the voltage down to about
90 VAC with a variable autotransformer for safety, but the 'phone rings loudly
and continuously.

If you close the hookswitch, you get a loud buzz. ;^)

I've never tried it on one of the new solid state (easily damaged, cheap,
poorly made, etc., etc.) 'phones so widely available, but ALL of the old-style
Western Electric sets I've tested (just under a dozen, I'd imagine) ring
just fine at 60 Hz. The ring does seem a little "buzzy" or rapid, as you'd
expect.

I don't speak for every 'phone, but you can ring _some_ of 'em with 120VAC.
