                         // At this point we should have the new session ID
                         // stored in the settings. Send a new conference IQ.
-                        this.room.moderator.allocateConferenceFocus();
-
-                        resolve();
+                        this.room.moderator.sendConferenceRequest().finally(resolve);
                     })
                     .catch(({ error, message }) => {
                         xmpp.disconnect();
