+ * Remove a call from the conference.
+ * @param call a call that has been previously merged into the conference.
+ *
+ * After removing the remote participant belonging to the supplied call, the call becomes a normal call in paused state.
+ * If one single remote participant is left alone together with the local user in the conference after the removal, then the conference is
+ * automatically transformed into a simple call in StreamsRunning state.
+ * The conference's resources are then automatically destroyed.
+ *
+ * In other words, unless {@link #leaveConference()} is explicitely called, the last remote participant of a conference is automatically
+ * put in a simple call in running state.
