Additional conferences created by a user beyond the default personal meeting room have options regarding expiration of that conference. By default, conferences will end and be removed from Nefsis 1 hour after the conference starts and is available for users to join. If a conference is set to expire 1 hour after it begins, but at that 1 hour mark there are still users in the conference, Nefsis will allow the meeting to continue until everyone has left. 15 minutes after the last user has left, the conference will be deleted and removed from Nefsis. The owner of the conference has the ability to modify this setting or to completely disable conference expiration. If conference expiration is disabled, then conferences will function identically to e/pop conferences in that the owner or a Host in the conference would have to manually end the meeting.
