This phone is my project. I'm happy to answer questions.
But my intent was for it to be as visually and functionally identical as possible to a phone booth you would've found on a street corner a few decades ago, just in an unusual place (and free). I've avoided anything in the normal usage of it that would deviate from that.
The single phone line was mostly at capacity with the /r/BurningMan crowd trying to call, though. I suspect with several times as many people dialing, sadly that has to mean fewer people can succeed. Hopefully people are still having fun with it, though.
Your version is way cooler. Thanks for bringing a little magic to the playa.
Until then, it got Internet via Burning Man itself through what they call the "participant network", which they still provide: https://internet.burningman.org/
This consisted of setting up a Ubiquiti NanoBridge (then later NanoBeam) with their supplied config on top of a 20 foot tower aimed at the 60 foot radio tower near Center Camp. Sometimes they wouldn't provide the config or get the participant network running until like Tuesday or Wednesday of event week, it might at best provide 400kbit/sec total or have permanent 50% packet loss, or just be down for days at a time. It wasn't great.
I hear it has drastically improved in recent years, but I haven't tried using it.
Great work!
For 2026 the booth was setup from Sunday, August 30 around 1pm to Sunday, September 6th at 6am, but was broken for a little over a day starting Thursday afternoon due to a failed power supply and a discovery that our spare was a dud.
Due to the widespread publicity, it was overwhelmed with incoming calls, receiving 33,400 total. Only 1,270 (3.8%) calls were answered for a total talk time of 44.5 hours, 1,600 (4.8%) weren’t answered within after 6 rings, and 30,500 calls (91.3%) got busy signals or other errors. Of the 7,200 unique phone numbers that tried to call, only 970 (13.5%) were able to actually talk to someone.
There were fewer outbound calls this year, presumably due to the booth being busy with incoming calls. There were 1,140 outbound calls to 650 different numbers in 30 countries, for a total talk time of 26.1 hours.
There were 1,460 outbound calls successfully made to 835 different numbers in 23 countries, with a total talk time of 34.8 hours. (This is down about 40% from peak years ago, now that there's more cell service and Internet available at Burning Man.)
There were also 5,658 inbound call attempts, and 676 (12%) were answered with a total talk time of 17.2 hours. 4,070 incoming calls got a busy signal and 912 got no answer.
And you can't make an emergency call on it (which is written in all caps on it); flagging down someone with a radio is the right way to get emergency services out there.
And there are occasionally people who have trouble with the concept of "free 5 minute call" (that it hangs up after) not meaning "just keep dialing back for an hour or two", even with a long line behind them. I can't ban specific outgoing numbers with voip.ms, but once I ended up just disabling all calls to the country that a problematic user kept coming back and repeatedly redialing.
Here's a list they maintain of current devices: https://wiki.voip.ms/article/ATA_Devices
Maybe they could come back and offer "free" service in high-density areas and fund via pre-roll ads or something. But perhaps the culture of remembering phone numbers is too far gone and it's easy enough to find charging.
Thank you for making and posting about this!
Telstra, the formerly state owned incumbent telco is obliged under their universal service obligation to provide a certain number of payphones, but it costs more to collect the coins than the phones earn in revenue.
One detail about the status page: the rows read upside down. "Online Phone connection". Once you realize what it means your brain can flip it, but the more natural order would be "Phone connection Online".
Good show!
