3-Way Conference Calling

Updated September 2019

Note: This feature is currently only available when using Firefox as your browser.

Once logged into (in Firefox), start a voice call.

Once the call is active, click on the “+” sign button (the 'Conference' button) on the right side of the call handling options.

Enter the phone number, extension, or SIP address of the third user you wish to add to the conference in the text field that appears below. You can access a phone keypad by clicking on the keypad icon. Also, if you want to conference in a person who is in your Contacts list, simply start typing in her name and select the contact from the dropdown that appears.

Click “Add to call” or hit enter.


When the third person answers the call, you should be on a 3-way call in Firefox (you'll know because both of the call cards on the left sidebar will be red). If one of the call cards is gray, click on the "Resume" button for that call to start the 3-way call:


If you wish to end a call with any of the two participants, you can click the “End” button on the particular call's card on the left sidebar. If you wish to end the call with both parties, click the “End” button on both call cards.
