Hi HN, As a weekend project, I hacked together a physical phone, a Raspberry Pi running Asterisk and Twilio, to let toddlers safely make international calls. I’ve documented the setup in this write-up and published the code + Ansible playbooks on GitHub so others can replicate it. I built this so kids of expats can easily stay in touch with family on other continents. Would love feedback from anyone who’s worked on something similar or tries building this themselves! writeup: https://wip.tf/posts/telefonefix-building-babys-first-intern... github repos: -…

I've been obsessed for the past ~year with the possibilities of talking to LLMs. I built a bunch of one-off prototypes, shared code on X, started a Meetup group in SF, and co-hosted a big hackathon. It turns out that there are a few low-level problems that everybody building conversational/real-time AI needs to solve on the way to building/shipping something that works well: low-latency media transport, echo cancellation, voice activity detection, phrase endpointing, pipelining data between models/services, handling voice interruptions, swapping out different…

Hi All ,I been working on my idea , A Voice CRM solution for 2 years.When I started brainstorming the idea the only option I have to receive phone calls thru browser was a flash widget or use 3rd party providers like Twilio or Phono .

I built CallSky as a simple alternative for international calling after Microsoft shut down Skype earlier this month. The app lets you make calls to landlines and cell phones worldwide starting at $0.01/minute with a pay-as-you-go model. I noticed that while Teams replaced Skype's video/chat conferencing, it doesn't offer the same affordable PSTN calling that many people relied on. WhatsApp and other messaging apps don't solve this - whether you're an expat calling the IRS for taxes, reaching elderly family members who don't use smartphones, or contacting people in areas with…
