  - Downloading content to the server
    When downloading content to the Sametime sever, it must be downloaded to the web/download directory.
  - Adding virtual backgrounds to the global library
    By default, you can customize your meetings with virtual backgrounds. As an administrator, you can choose which backgrounds are available to all users.
  - Configuring alternate STUN servers
    Sametime Meetings uses public Google STUN servers by default. To use different STUN servers, you must complete this procedure before installing Sametime Meetings.
  - Setting up business cards
    You can configure the Sametime server so that business card information about an individual displays when a user hovers over a name in a chat window or a contact list. Business card information also displays at the top of an active chat window.
  - Configuring LDAP
    Sametime supports LDAP directory servers as the user repository.
  - Updating the time-to-live index for persistent chat
    The time-to-live (TTL) setting defines how long the chat history is stored in the database. The default value is 90 days. However, administrators can update the value based on the organization's preferred setting.
  - Managing secrets in Kubernetes
    Sensitive information such as passwords, service account names, certificates, and other confidential data needed by Sametime pods are stored in secrets. In addition to helm charts and configuration map, the Sametime configuration is also derived from secrets.
  - Applying configuration changes in Docker or Podman
    Configuration files contain environment variables that can be changed and applied to the Sametime server.
  - Applying configuration changes in Kubernetes or Openshift
    Configuration files contain environment variables that can be changed and applied to the Sametime server.
  - Chat

  - Meetings
    This contains configuration steps specific to the HCL Sametime Meetings server.
    - Disabling secure meeting room names
      Users are provisioned with a personal meeting room the first time that they log into their meeting. Their personal meeting room is created with a secure name that cannot be easily guessed by other users. For example: be:MeetMe.CWGRAff90q9HETLne4mhzA.
    - Enabling conference dial-in
      You can set up your environment to allow users to dial in to a meeting using a SIP-capable phone system that is connected to a public switched telephone network (PSTN). This feature uses the ilink TeamCall Meeting Gateway (TMG).
    - Configuring alternate host name for Web Chat
      The default host name for Meetings and Web Chat are the same. However, you can configure Web Chat to use a different host name. In other words, you can use your chat host name instead of the default. There is a secondary cookie that is also used in the meeting authentication flow where if the cookie is present, then the redirect target is pulled from the cookie instead of the TARGET= parameter.
    - Enabling meeting dial-out
      You can enable the dial-out option on Docker and Kubernetes.
    - Configuring the maximum number of meeting participants
      A maximum of 100 users are supported in a meeting regardless of the selected meeting mode. To reach a wider audience, you can start a live stream and share the link to all intended participants.
    - Enable Videobridge for TCP
      This section provides steps to configure TCP for media streams using TCP port 4443.
    - Disable sharing of meeting recording
      By default meeting recordings can be shared with others. You can change a setting to disable sharing of meeting recordings.
    - Enabling Microsoft Outlook Add-in
      To use the Sametime Meetings add-in for Microsoft Outlook, it must be enabled on the Sametime server. The add-in is provided as part of Sametime installation package.
    - Setting up a TURN server
      A TURN server can be configured to provide for efficient traffic flow within your Sametime meeting.
  - Integrating with other applications
    Integration with an application such as Verse prior to Sametime 12.0 requires the legacy web-client interface. Beginning in Sametime 12.0 the legacy web-client is not enabled by default, but can enabled when needed for integration with other products.
  - Monitoring your meeting and chat metrics with Grafana
    Sametime uses the third-party software, Grafana, to generate insightful graphs and visualizations derived from time-series database (TSDB) data. Integrating Grafana into your Sametime environment allows you to see analytic metrics about Sametime meetings and chats on a Grafana dashboard. The metrics can be used to monitor Sametime usage and resources.
  - Push messaging through a proxy
    Depending on your network settings, your firewalls could prevent Sametime proxy from connecting to push networks like Apple Push Notification Service (APNS) and Firebase Cloud Messaging (FCM) through the Internet. Sametime supports the sending of APNS and FCM messages through a proxy server. If you need to send APNS or FCM message through a proxy server in your environment, you need to configure the settings for the messages you want routed through the proxy.

Configuring the maximum number of meeting participants

A maximum of 100 users are supported in a meeting regardless of the selected meeting mode. To reach a wider audience, you can start a live stream and share the link to all intended participants.

About this task

You can lower the maximum capacity to any value below 100 as needed. Users who attempt to join a meeting that has reached maximum capacity receive a message indicating that the meeting room is full.

The number of meeting video streams that display in the Meeting window is based on the following:

The value set for the maximum number of active video streams to display
Most recent active video streams

For example, if the maximum number of participants is 50 and value for maximum video streams is 7. The number of participant tiles displayed is fifty. However, the number of displayed video streams is seven, which includes you. That is, six other video streams plus your video stream are displayed. The six participants displayed are the most active video streams and change as participation in the meeting changes.

The default for the maximum number of displayed video streams is nine. To set the maximum to a different value, see Increasing the number of video streams displayed during a meeting.
