Is there a gem that normalizes and format US phone numbers in ruby?

Question

I was using phony to format phone numbers (meaning, if I put in xxx-xxx-xxxx it would convert to a string, and also tell if there is a (1) before to remove it).

But

Answer 1

def format_phone_numbers(n)
    "(#{n[-10..-8]}) #{n[-7..-5]}-#{n[-4..-1]}"
end

format_phone_numbers('555555555555')

"(555) 555-5555"
