Created in 2000, was both the first free conference calling service in the united states and the first conference calling service that was not owned by one of the major telecommunications companies. Our early business model was based on the same model as party lines, giving us a small cut of the fees collected by the telephone provider.

As grew, the need for larger bridge capacities became clear, so we designed the first ever board that would allow up to 256 participants to join a single call, changing the conference calling landscape for the second time in a few short years. history

In September 2015, we re-launched with a new website and a number of new features including download-free, WebRTC-based video conferencing and screen sharing. The use of WebRTC allows for a high-quality browser-to-browser connection without additional software downloads. While we were not the first conference calling product to use WebRTC for audio we are the first free conference calling product to offer fully integrated WebRTC-based video conference calling and traditional dial-in numbers.
