    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 .
