Last time we took a look at the WiPhone, back in the middle of last year, the ESP32-based Voice over IP (VoIP) phone was closing in on full funding on Kickstarter. Since then it’s been a bumpy ride for the project towards shipping to its backers. That’s to be expected, as scaling from a single prototype to a full scale production run isn’t easy. Everyone runs into problems with manufacturing, and how you handle that as a startup that is going to decide whether you succeed or fail, not the problems themselves.
