Call

The Call class represents a single call or conference, incoming or outgoing. For an incoming call/conference, get the call instance from the IncomingCall event. To create an outgoing call, use the Client.call API. To create an outgoing conference, use the Client.callConference API.

Methods

active():

Returns 'true' if a call is active, otherwise returns 'false'. A single call (either incoming or outgoing) is active by default, all other calls are inactive and should be activated via the setActive method. Only the active call sends and receives an audio/video stream.

Returns

    boolean
