Abstract
A conference call may be implemented between multiple user devices via a conference call server. A user may use a graphical interface of the user device to communicate with the conference call server and control the conference call in various ways. For instance, the user may add a user device to the conference call, drop a user device from the conference call, organize the user devices into conference call groups, record one or more user devices within the conference call, prevent a user device from hearing the audio input of another user device, filter out background noise from the conference call, and receive a call from outside the conference call without having to leave the conference call.
