Step 1: Identify Your Snom Conference Phone and MAC Address

You can find the model and MAC address on the labels at the back or bottom of the phone.

Make a note of the MAC address as you’ll need this for the configuration. Learn more about your IP Phone MAC address.

Step 2: Add The Phone to the Extension

From the admin console in your web client:

  1. Go to “Users” and select the user you want to add a phone for.
  2. Click the “IP Phone” tab. Click “Configure a phone” to add a device.
  3. Now select your device model from the dropdown menu.
  4. Enter the MAC address without dashes or colons, and click “Add phone”.

Step 3: Router Phone, SBC or LAN?

  1. If 3CX is in the cloud, you must use a router phone or SBC.
  2. If 3CX is on-premises or self-hosted, you have an additional option “Local LAN/VPN”.
  3. Click “Add Phone” to save the device for this extension.

Step 4: Connect the Phone

3CX will now create provisioning files for the device and make these available on the provisioning URL. The phone must connect via LAN to this URL to retrieve its configuration information and authentication details. You have the following options:

  1. RPS - Connect the phone to the network within 14 days. If it is already connected, restart it. The phone will be configured automatically.
  2. PNP - If 3CX is on-premise or connected via SBC, you can connect the phone to the LAN and look for it in the PNP list (Admin Console > Phones > PNP Phones). Select and assign it to the extension you configured above. Your LAN network must be connected to the same local network as the SBC or 3CX system.

  1. Alternatively, you can log in to the phone's web UI and enter the URL manually. You can also use DHCP option 66.
