Hacker Turns a Payphone Into a Free VoIP Line for Random Burning Man Calls

Someone gutted an ordinary phone booth, ripped out its coin mechanism, and rewired the internals to place calls over the Internet instead. The result sits on a corner of Black Rock City during Burning Man, letting anyone dial almost anywhere in the world free for five minutes — no payment, just VoIP running behind a nostalgic piece of hardware.

The booth also works in reverse. Passersby can dial numbers of their own, so people off-playa may get an unexpected call from +1 (775) 557-4848, placed by a friend or a complete stranger walking past. The project even nods to modern telecom friction: because carriers often silence unknown numbers, the site suggests saving the line as a contact so return calls actually ring through.

It’s a small, self-contained hardware hack rather than anything security-relevant, but it’s a tidy example of repurposing legacy telephony infrastructure with cheap Internet calling. Live call-activity status and a Reddit thread round out the setup, giving curious callers a way to see whether the line is busy before they try their luck reaching a random Burner.
