Once a conference bridge invitation has been initiated, an xMatters conference bridge is placed on reserve and will start once users accept the invitation and join the call.
A conference bridge becomes active only when two or more participants join the call. If the first user to join the call leaves before a second user joins the call, the conference does not end because it has not been made active. An active conference ends when the participants leave the call or the conference is manually ended. Once a conference has ended, participants cannot join the call.
If users are connected to the same xMatters conference bridge for more than 24 hours, they are prompted to reconnect to the call by hanging up and dialing back in, or having xMatters call them back to automatically reconnect. A user can indefinitely refresh their connection to a conference bridge in 24-hour periods. xMatters will play a warning message 15 minutes before the call is set to expire and prompt users to press 1 to extend the bridge.
A conference bridge will terminate after all users leave the call or when the alert is terminated. A conference bridge being held in reserve for users to join will terminate automatically after 24 hours, or if the alert is terminated.
