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"
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 |
- 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.
