# Inviting users to the conference
You can add participants from your address book right when creating a conference as it is described in the corresponding section.
Moreover, if you are the moderator of an ongoing conference, you can invite participants to join it. There are three options to do so.
Go to the list of participants using the button
and click Add participants.If you call any user during a conference, this user will be invited to join your current conference.
Third, if you are the conference owner or have operator rights, you can go to the participants list in the real-time meeting manager and invite users by clicking the
button to the right of the search bar.
The users, who did not join the meeting, will be displayed as a separate Unconnected group in the conference participant list. You can remove any of these participants (right-click on a participant to open the context menu and remove) or clear the entire list by clicking on the 
button.
# Inviting a user group to the conference
To add a user group to a conference, go to the group list display mode and click Invite to conference in the group context menu. You will enter the conference creation menu.
In the same way, you can invite the group to an active video meeting if you are the meeting moderator.
To add a new participant or group without leaving the conference window, you need to go to the list of conference participants and click Add participants.
# User group actions

# Disconnecting participants
The moderator can disconnect a participant or another moderator during a meeting (removing the conference owner is unavailable). To this end, right click on the user name and select Disconnect participant in the list of conference participants (don't forget to go to the list of participants rather than the address book).
You will need to confirm the removal of a participant by clicking on the corresponding button. Please note that if you have marked the Do not allow to rejoin box, the user will be unable to join this meeting later.

The corresponding option will be available in the conference card when selecting this event in the list of meetings either in the client application scheduler or in the personal area.
# Locking the conference
A moderator can lock the conference for new participants at any moment. This meeting will be unavailable to new participants either temporarily until it is unlocked or up to its ending.
You can lock a meeting in one of these ways:

Go to the real-time meeting management section, click on the button
and select Lock conference.

it cannot be joined by:
authorized server users who were not explicitly added to the list of participants after the conference was locked
users who were added to the list of invited participants before the conference started, but did not connect before the conference was locked
guests (in case of a public conference).
Each time when a conference ends, its access status is automatically set to the default value unlocked.
You can make a conference accessible to new participants in the same section where the conference was locked. Select the option Unlock conference in the conference card.
# Ending the conference
If you are the conference moderator, when you leave the conference (by pressing 
) you will be asked whether you want to leave the conference or end the conference for all participants.
If you choose Leave (without ending it for everyone), you can re-join it in the following ways:
- Call its ID or join URL
If you are the owner, you will only need to create a new conference. The application will automatically redirect you to the conference where you are the owner (if at least one participant still remains in the meeting).
