Tips for Using Conference Rooms

What's the difference between permanent and temporary conference rooms, and why choose one over the other?

Are always available. You can use them for ad hoc meetings, without having to go to the trouble of scheduling an event. Just send a quick blast to everyone, asking them to call in, and what room number to use.
Are only available to members. To access a permanent room you must call from a phone number that is listed on your Member Page, or login with your Directra telephone login ID and PIN. This makes the rooms more secure, but prevents you from inviting non-members.
Can have short, easy-to-remember room numbers. This is handy if you have frequent meetings in the same room.

May only be used with scheduled conference events, and are only available during the scheduled time.
Are accessible to anyone who knows the 6-digit room number, including non-members.
