Grandstream HD Video Door System Overview

This document uses the Grandstream GDS3710 as the reference device. The Grandstream GDS3712 is also compatible with CyberGate.

Security Features

The Grandstream is certified for secure communication with CyberGate using:

• SIP TLS (Transport Layer Security)
• SRTP (Secure Real-time Transport Protocol)

Recommendation: Start by configuring the Grandstream using the basic steps first. If the connection and test calls are successful, modify the configuration to use secure communication (see Secure Communication section).

Step 5: Configure Multi-ring Group

Pressing the call button on the Grandstream will initiate a call to the number configured in the Door System Settings (e.g., 123). Since this number is not a valid Teams user, you must configure a Multi-ring group to route calls to Teams users.

1. Navigate to: https://admin.cybergate.cybertwice.com

2. Log in using a Microsoft account with admin privileges

3. Navigate to the Multi-ring Settings menu

4. Click the blue ‘Add multi-ring group’ button

5. Configure the following:

Field	Value
Name	Enter the ‘Number Called When Doorbell Pressed’ from the Grandstream (e.g., 123)
Description	Describe this Multi-ring group

6. Click ‘Save’

7. Add the Teams users you want to be notified when someone rings the doorbell

Note: Use only the first part of the Teams username (without the domain name) — the domain will be added automatically.

---

Testing the Configuration

Configuration is now complete! Here’s what happens when someone presses the call button:

1. The Grandstream places a call to CyberGate using the configured number (e.g., 123)
2. CyberGate answers the call and recognizes 123 as a Multi-ring group
3. CyberGate calls all Teams users in this group
4. The first Teams user to answer (by clicking the camera symbol) is connected to the Grandstream
5. The call is established and video displays within approximately 3 seconds

Opening the Door from Teams

1. During the call, click the Dial pad symbol in the call screen
2. Enter the ‘Remote Pin to Open Door’ code configured earlier
3. This triggers the relay in the Grandstream and opens the door

---

Secure Communication over SIP-TLS

For encrypted communication with CyberGate, modify the configuration as follows:

Enable TLS and SRTP

1. Navigate to Account → Account 1

2. Modify the following settings in SIP Advanced Settings:

Field	Value
Local SIP Port	5061
SIP Transport	TLS
Enable SRTP	Enable and Forced

3. Click ‘Save’

Verify Secure Connection

Check the registration status in Status → Account Status to confirm the secure connection.

All SIP and audio traffic to/from CyberGate will now be encrypted.

Feature 1: Availability

How It Works

The CyberGate app uses the same credentials as Microsoft Teams and automatically retrieves information about Multi-ring groups you belong to.

Example Scenario

In this example, the user koos.ridder@cybertwice.com is part of two Multi-ring groups:

Group	Members	User Role
Sales personnel group	3 users	Supervisor (*)
The wall group	2 users	Normal user

User Roles

Role	Permissions
Supervisor	Can set availability for ALL users in the group, can add/remove users
Normal User	Can only set their OWN availability status

Availability Status

Status	Effect
Available	You can be called by CyberGate
Unavailable	You won’t be called by CyberGate

Note: Availability status changes take effect immediately.

Tip: To configure the supervisor role for a Multi-ring group, use the CyberGate Management Portal.

Feature 2: Devices

How It Works

The Devices menu shows an overview of all configured devices in your Tenant, sorted by location. You can filter results to find specific devices.

Device Tile Information

Each device tile displays:

Information	Description
Device Type	Intercom, camera, or audio/paging
Device Name	Configured name of the device
Online Status	Whether the device is online or offline
Recording Status	Whether recording is enabled
Two-Way Video	Whether two-way video is configured

Connect Button

If a device is configured to receive calls from Microsoft Teams, a Connect button will appear. Clicking this button initiates a call to the device.

Note: The devices shown to a user can be limited using the Device access settings in the CyberGate Management Portal.
