The Fastest Way to Connect an Intercom to Teams with CyberGate

 
Prerequisites

M365 Business, M365 Enterprise, or O365 license
A SIP-compatible video intercom (check the CyberTwice compatibility list)
Admin access to your firewall and intercom device
Global Administrator privileges in your Microsoft 365 tenant

 
1. Purchase CyberGate


Purchase via Microsoft AppSource or Azure Marketplace.

 
2. Provide Admin Consent


This step is mandatory - CyberGate needs your consent for a limited set of MS Graph API permissions to be able to call Teams users in your organization. The consent grants CyberGate the necessary permissions to initiate calls to Teams users within your Teams Tenant.
Follow these steps:

Log into the CyberGate Management Portal
Go to Basic → Global
Click the "Provide admin consent" button
You will be redirected to Microsoft to grant the required access rights
Log in with your Global Administrator account and accept the requested permissions
Once completed, the portal will show: "Admin consent has been provided for this tenant"

Note: This must be done by a Global Administrator of your organization. The consent grants CyberGate the necessary permissions to initiate calls to Teams users.

 
3. Configure CyberGate in the Management Portal


 
Network Settings:

Go to Basic → Network
Add your WAN IP address (or IP range) where the intercom is located

Device Settings:

Go to Basic → Device
Click Add Device and enter:

Display Name (e.g., "Front Door Intercom")
Type (Intercom, Pager, or Camera)
Location


The portal will automatically generate a SIP Authentication Username and Password - copy these for the next step

 
4. Configure Your Intercom Device


On your intercom's SIP settings page, enter:



Setting
Value


SIP Registrar / Server
cybergate.cybertwice.com


SIP Username
(from portal)


SIP Password
(from portal)


Transport
TCP (port 5060) or TLS (port 5061)

 
5. Firewall Configuration


Open the following outbound ports on your firewall:



Port(s)
Protocol
Destination
Purpose


5060
TCP
cybergate.cybertwice.com
SIP messaging


5061
TCP
cybergate.cybertwice.com
SIP-TLS (secure)


30000–30199
UDP
cybergate.cybertwice.com
(S)RTP audio/video



 
Important:

Always use the DNS name cybergate.cybertwice.com - IP addresses may change without notice
Disable SIP ALG on your firewall (this setting often causes connection issues)

 
Optional - Set Custom Display Name


By default, calls show as "Intercom" in Teams. To display your custom name:

Download the PowerShell script from the CyberGate Device settings page
Run it with Global Administrator or Teams Administrator permissions

 
That's It!
Once registered, visitors press the intercom button and the call arrives in Microsoft Teams with two-way audio and live video. You can answer on desktop, desk phone, or the Teams mobile app - and open the door directly from Teams.
