On the independently-owned and run Vonage Forum, I’ve run across a fascinating thread in which a user named Cozzman is trying to figure out if there’s a way to use his Vonage service with his rotary phone.

Then, after reading Cozzman’s post, I got it. Just like some people still build radio-controlled antique cars, the challenge of marrying old and new technologies is the kick here.
