All you have to do is sign up and create a LINE profile to enjoy its facilities. The call recipient need not have the LINE app. It not only lets you make free international calls for as long as five minutes but also offers you a platform to share messages and media with anyone. If you are looking for a FireRTC alternative that also acts as a social platform, LINE is the most suitable option. You can enjoy the Basic plan for calling internationally to 64 listed companies at $10 per month. You can enjoy the unlimited international call facility by registering and subscribing to one of the paid plans. On a comparative note, it can be distinguished from FireRTC or Skype because it routes all the calls from the web browser to phone-based endpoints using its VoIP technology. However, PopTox offers limited free VoIP international calls from your browser to mobile or land phones made on a single day. Just dial the phone number and press on Call to make the free call from anywhere to anywhere. That means you do not have to download the app, nor do you have to use any kind of plug-in. It uses your WiFi or cellular network to connect to the punched phone number. You can now make calls by simply opening the PopTox webpage from any standard browser, either from your smartphone or PC.
PopTox is a widely known FireRTC alternative popular for its free VoIP calls.
