  - 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
    Configuration files contain environment variables that can be changed and applied to the Sametime server.

  - Meetings
    This section will discuss Meetings 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.
    - 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.
    - 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).
    - Enabling meeting dial-out
      You can enable the dial-out option on Docker and Kubernetes.
    - Configuring the maximum number of meeting participants
      Sametime currently supports a maximum of 100 users 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.

      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.

Configuring the maximum number of meeting participants

Sametime currently supports a maximum of 100 users 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

By default, you can host a meeting with up to 100 participants. 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 encounter a message indicating that the meeting room is full.

Note: The greater the number of concurrent users accessing the server, the greater the resources consumed, particularly CPU resources. Other factors, such as meeting recordings, can influence the total capacity. Refrain from changing this setting without proper sizing information from HCL. For sizing-related questions, contact HCL.

Procedure for Kubernetes

Place the helm/values.yaml in edit mode.
```
vi helm/values.yaml 
```

Edit the following line:

MaxOccupants= <new value representing the number of total users in a meeting>

Save the file.
Restart the Sametime Meeting Server using the instructions in the topic Starting and stopping Meeting servers.

Procedure for Docker:

Place the docker-compose.yml file in edit mode.
Under the prosody section, modify the value of MAX_OCCUPANTS:
```
MAX_OCCUPANTS=<new value> 
```
Save the docker-compose.xml file.
Restart the Sametime Meeting Server using the instructions in the topic Starting and stopping Meeting servers.
