How to format this international phone number in Rails?

Question

If I have an international phone number such as this:

0541754301

how can I format it to produce something like this:

Answer 1

There's phony and phone gems available.

Phony.formatted('18091231234', :format => :international).should == '+1 809 123 1234'

or simliarly

phone.format("+ %c (%a) %n") # => "+ 385 (91) 5125486"
