WebCall is a web-based utility which allows anyone to participate in a conference call by simply using a Chrome or Firefox browser with a computer headset. There’s no separate software program to download or install, and no registration required. WebCall uses an emerging technology called WebRTC that enables real-time communications over the Internet. WebRTC is enabled in the current versions of Chrome, Firefox, Opera and Chrome on Android.
- Since WebRTC is not supported in either Internet Explorer or Safari, WebCall is not available through those browsers. Also, WebRTC is not enabled in Apple iOS, so WebCall will not work on iPhones or iPads.
HD Audio Quality. WebCall delivers HD Audio (using the Opus codec), providing a crisp high quality audio experience using your computer. Best of all, WebCall works wherever you have an Internet connection, so whether in your office or in a hotel room half-way around the world, WebCall provides easy access to your conference calls.
Accessing WebCall. There are two methods for accessing WebCall. (These methods may not be available to all users. Contact customer support for more information.) The Host Control Panel may display a small WebCall button near the top right corner, which allows you to instantly connect as a Host. There is also a standalone version of WebCall, which allows either host or non-hosts to join conference calls, requiring the user to enter the Conference ID.
Using WebCall via the Host Control Panel
Clicking on the WebCall button will prompt for a Name and Email, and pressing the Call will automatically connect you into the conference bridge as a host, displaying a small status panel in the upper right corner, as shown below:
If you see the message “Listen Only Mode”, this indicates that you are not using a secure https: connection, and no audio is being sent from your microphone into the conference. You need to re-enter the control panel web address using the https:// prefix (instead of http://).
1. High-Speed Internet Connection
Some mobile data connections may not deliver acceptable audio performance. In order to transmit audio from your microphone, a secure connection (https:) connection is required, and you need to allow your browser to access the microphone.
2. Headset or Earbuds with Mic
Built-in laptop microphones and speakers may introduce disruptive noise and echo into the conference call. While WebCall incorporates noise suppression and echo cancellation technology, for best performance you should use a headset or earbuds.
3. Chrome, Firefox or Opera Browser
WebCall uses the WebRTC technology built into newer versions of the Chrome, Firefox, and Opera web browsers. Neither Apple nor Microsoft presently support WebRTC, so WebCall will not work with Internet Explorer, Safari, or any Apple iOS device.
