Looking for a way to setup permanent (or at least long lasting) conferences with 3cx. For example, systems like Asterisk allow you to reserve extensions for specific conference rooms that are always available. If I schedule a conference and put its end years out would that suffice or is the room destroyed as soon as all users log out? For that matter, when a conference is made via the conference extension, how long before someone else can make a conference using the same room number? The details on the doc pages are fairly sparse.
