  4. Enter the Sign-In Address. This is the Skype address for the endpoint in the meeting room.
  5. Enter the Username associated with the address, if any. You can choose to leave this blank if you are a Microsoft Office 365 user.
  6. Enter the Password for the Skype address account.

Managing a room

When you have added your meeting rooms to the room overview table, you can manage them at any time by clicking the Manage button that appears to the right of the room entry. This takes you to the room information page. This displays the meeting room name, location, and endpoint configuration settings. It also allows you to change the firmware version for the endpoint, download diagnostics, and reboot the endpoint.

  • To edit the name or location of the meeting room, click the Edit button that appears to the right of the room name
  • To change the firmware version for the GTm, select the version from the dropdown menu within Room Management then click Change Firmware Version
  • To reboot the GTm, click Reboot within Room Management
  • To download diagnostics for the GTm, click Download Diagnostics
    The diagnostics log may be required by StarLeaf support in order to help you troubleshoot any issues you experience
  • To unpair the GTm from the room and return it to factory default settings, click Unpair. The touch panel will display the QuickConnect screen
  • To delete the GTm from Maestro, first unpair the GTm and then click Delete

The QuickConnect code is displayed in the meeting room until the endpoint is connected. Once the endpoint is connected, the QuickConnect code isn’t shown, but the serial number, MAC address, firmware version, and password are displayed under Info.

Changing the endpoint settings

When you are managing a meeting room, click the Edit button that appears to the right of Settings. All the options under the Settings tabs become editable.

For a brief description of the editable settings, refer to the list below:

  • General tab
    • Language: the language presented on the GTm endpoint
    • Timezone: the timezone in which the meeting room is located
    • Standby timeouts: Camera standby is separate from screen standby such that you can locally share content from a PC or other source without causing the camera to come out of standby
  • Skype tab
    • Sign-In Address: the Skype for Business address for the endpoint
    • Username: the username associated with the sign-in address, if any
    • Password: the password for the sign-in address
    • Automatic Connection Settings: if enabled, the connection settings connect automatically where possible. If you cannot or do not want to connect automatically, disabling this setting allows you to set the Internal Server Name and External Server Name
    • Disable video-based screen-sharing: When VbSS is enabled, the GTm will use VbSS if it is available and, where it is not, fall back to RDP
  • Audio tab – if the room’s endpoint is a GTm 5250
    • Microphone selection: If you have connected a StarLeaf microphone, ensure StarLeaf XLR microphones is selected. If you have connected a third-party XLR microphone, select Third-party microphones. If you have connected a microphone or a microphone mixer to the Line In connector, select Line In
      Additional settings exist for each microphone option
  • Camera tab
    • Frequency: when you have connected a camera to the codec, adjust the power line Frequency setting
    • Camera presets: Camera presets are pre-defined camera positions. For example, a pre-defined position that points the camera at the whiteboard, or that changes the camera to a wide-angled view. Room users can select the position they require from the Camera Control tab on the touchscreen controller and they can swap between presets at any time.

      GTm room systems can have up to five camera presets.

  • QoS tab
    • If you have QoS configured on your network, you can configure the GTm 5250 with the relevant settings and enable traffic shaping
  • Exchange tab
    • Copy Skype For Business Credentials: if your credentials for Exchange and Skype for Business are not the same, you can choose to copy the credentials, otherwise you need to specify the Email address, Username, and Password
    • Enable Autodiscovery: if enabled, configuration settings are automatically discovered. If you cannot or do not want to configure this automatically, disabling this setting allows you to set the EWS URL
  • Touch Panel tab
    • Interface: switch between the Skype for Business interface, the Windows 10 interface, and the Classic StarLeaf GTm interface. The Windows 10 interface allows a number of configurable options, described below:
    • Lock Touch Panel: lock the touchscreen controller and set a 4-digit unlock PIN
    • Enable ECAPI: if you want to enable the use of the API, an ECAPI¬†Key is provided. This is a 32-character key specific to the endpoint
  • Certificates tab: select the certificate from the list to be used for the room. If no certificates have been added in the Certificates menu, this list is empty
  • WiFi tab:
    • Enable or disable WiFi on the GTm
    • Choose a WiFi channel
    • allocate a Miracast name (the name that appears in the list of content receivers)

GTm status

Maestro displays GTm status for all rooms in Management > Meeting Rooms. The possible status options are color coded to indicate the severity of a state as follows:

  • Green: For example, OK. A green status message indicates that the GTm is functioning normally
  • Blue: For example, New Room. A blue status message indicates that the GTm is in a transient state within normal operation. The message might indicate that the GTm is upgrading or signing into Skype for Business. New Room indicates that the room has been set up but the quick-connect code has not been entered into the endpoint
  • Red: For example, Disconnected. A red status message indicates an issue with the GTm that needs your attention. The message might indicate that the GTm has, for example, failed to sign in to Skype for Business or that it has failed to upgrade. Disconnected indicates that the endpoint in this room has been disconnected and is currently unusable
