WebRTC helped me to launch my startup after 2 years of waiting.▲42
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 . Thanks to WebRTC we now integrated our VoIP services to receive and make calls directly thru browser .Please have a look and give us your feedback .Thanks Voz.io Team .

I built an international calling platform for the past 6 months▲38
I built Voklit because I was tired of paying $2+/min to call banks and airlines overseas. Needed a US number that works anywhere with actual affordable rates. It's a web-based VoIP service (mobile apps coming soon). You get a real US phone number, pay-as-you-go minutes on top of a small subscription that covers the infrastructure. Bootstrapped, solo founder. Built with [Go/Next.js/ and Websockets] if anyone's curious about the stack. Adding more countries soon. Happy to answer questions or hear feedback.
