# Waiting room
When a user makes a call to TrueConf MCU without specifying a conference ID (in the format #h323:@<server_name> or #sip:@<server_name>), he/she will be placed in the waiting room. In this case, a notification will be displayed in the notification center of the TrueConf MCU control panel, and the counter number on the 
button will increase. Click on this button to open the list of users waiting for connection:
A user will remain in the waiting room until he/she enters the ID or the administrator moves this person to one of the conferences. After 60 seconds, waiting time will expire and the user will be disconnected.
To add a user, click the 
button, find the required conference in the list, and click the Move button.
