Procedure

Step 1. Add the Unify IP phone on PBX

Add the IP phone on PBX. The PBX will generate a configuration file based on the phone's MAC address.

  1. Log in to PBX web portal, go to Auto Provisioning > Phones.
  2. Click Add > Add.
  3. In the IP Phone section, enter the following phone information.

    • Vendor: Select Unify.
    • Model: Select the phone model. In this example, select CP210.
    • MAC Address: Enter the MAC address of the IP phone.
  4. In the Options section, configure the following settings.

    • Template: Select a desired template from the drop-down list.
      Note: You can select the default template corresponding to the phone model, or customize your own template. For more information, see Create a Custom Auto Provisioning Template.
    • Provisioning Method: Select Provision Link - FQDN (Remote) or Provision Link (Remote).
      The Provisioning Link field displays a provisioning link, which points to the location where the phone's configuration file is stored.
      Note: Note down the provisioning link, as you will need to use it later when configuring the DHCP server.
  5. In the Assign Extension section, assign an extension to the IP phone.

    Note: If your desired extension is not listed in the drop-down list, it indicates that the extension has been associated with an IP phone or gateway.
  6. Click Save.

Step 2. Configure DHCP option 66 on DHCP server

In this example, a DHCP server is set up in the IP phone’s network to deliver the provisioning link (obtained from the PBX) to the phone.

Note: This method is suitable for bulk provisioning. For a single device, you can manually enter the provision link in the phone's web interface.
  1. On PBX web portal, copy the provisioning link from the phone's detail page.

  2. On the DHCP server, set up option 66 with the provisioning link.

    In this example, the configuration is shown below:

Result

  • After rebooting the IP phone, it gets an IP address from the DHCP server, downloads the configurations from the PBX via the provisioning link, and applies the settings automatically.
  • The extension is successfully registered on the IP phone. You can check the registration status on Auto Provisioning > Phone on the PBX web portal.
