Because your meeting room is pin-less, anyone can jump in. If you wish to avoid unwanted guests in your meetings (perhaps you're running back-to-back) you can easily lock the meeting through the Web conference. Just click the Lock Meeting button in the left-hand nav.
Your team-mates can still join the meeting when locked if:
- They join by phone using the numbers registered to their Jiminny account
- They join by the web if logged in using their Jiminny account
Any external guests will receive a message indicating that a meeting is still running and to re-join shortly. They will get this if joining by phone or via the web conference.
You can allow access again by toggling the Unlock Meeting button.
Note: there is no "knock" feature at present.
