Configuration of the Grandstream is now finished.
Pressing the call button on the Grandstream will initiate a call to the number you’ve configured in
the Door Sytem Settings menu at ‘Number Called When Doorbell Pressed’.
As this Number (e.g. 123) is not a valid Teams user within your Teams environment, you must
configure a Multi-ring group via the CyberGate Management portal. The Multi-ring group enables
you to ‘translate’ the dialed number (e.g. 123) to one or more valid and existing Teams user(s).
Navigate to the following URL: https://admin.cybergate.cybertwice.com
Log in to the admin portal using a Microsoft account with admin privileges and navigate to the
Multi-ring Settings menu.
Click the blue ‘Add multi-ring group’ button and provide the following information:
Name Enter the ‘Number Called When Doorbell Pressed’ from the Door
Sytem Settings menu in the Grandstream, in this case 123
Description Describe this Multi-ring group
Click the blue ‘Save’ button when done.

The configuration is now done.
The following sequence will take place when pressing the call button on the Grandstream:
• The Grandstream will place a call to the CyberGate using the number you’ve provided in the
configuration. In our example 123
• The CyberGate will anwser the call to 123, recognizes the 123 number as a ‘Multi-ring group’
• The CyberGate checks what Teams user(s) to call (as configured in the Multi-ring group) and will
place the call to all Teams users in this group
• The first Teams user that answers the incoming call in Teams (by clicking the camera symbol)
will be connected to the Grandstream
The call will be established and video will be displayed within ±3 seconds.
To open the door from the Teams call, click on the three dots (...) in the call screen and select the
‘Keypad’.
Use the ‘Remote Pin to Open Door’ code configured earlier in the Grandstream, this will trigger the
relay in the Grandstream and open the door.
