A FOSS PBX system that runs in Docker on your VPS. SIP hardware support, web interface, zero monthly fees, and a phone network that the robo-callers simply cannot find.
There was a time when the phone ringing was an event. You answered it. It was someone you knew, or at least someone with a real reason to call. That social contract held for decades and then it didn't.
Now the phone rings and the first instinct is suspicion. Let it go to voicemail. Check the number. The legitimate calls — family, friends, people you actually want to hear from — have been buried under an avalanche of robocalls, spam risk warnings, 15-second political messages, and people who are genuinely very concerned about your vehicle's extended warranty.
The solution isn't a better spam filter. Spam filters are a forever war where the spammers have unlimited resources and you're always one step behind. The solution is a phone network the spammers don't know exists. A private telephone network, on infrastructure you already own, for the people who already have your number — because you gave it to them personally.
That's Voice. It's not a replacement for your phone plan. It's a private hotline for the people who matter, built on the internet connection you're already paying for, running on a $5/month VPS, with hardware that costs less than a dinner out. When that phone rings, you answer it. Because you know who it is.
