And it is yours…

Not any different from publishing a phone number where you’ll be reachable, with call access you will enable your website to initiate and host a real-time call to any desired endpoint, just like with any standard phone or service number. You can embed a call access widget or place a click-to-talk button, and allow your customers to directly talk with whomever you want them to, right at the moment of their visit on your website. Distances are eliminated, as calling is free of charge for any caller in the entire universe.



Widget example on your website



Add real-time calls through browser as an extra channel to your existing infrastructure. Calls can be routed to any endpoint or multiple endpoints. We support DTMF, so navigating through an already existing IVR has never been easier. Register now for a 14-day free trial and experience perfect voice quality, almost 100 x better than conventional ISDN.


You are about to experience call access. Please make sure you are using Chrome, Firefox, Safari or Opera as a browser. Enter your your email address and phone number and click on "talk". Make sure the audio features on your device are enabled: microphone, speaker or headset.

The functionality was intentionally restricted to audio connections only. In settings, you can test them in advance. Your communication will be encrypted and none of your data will be stored. It’s gone the very moment you close your browser. Your webcam is not accessed.
