Auto Provision IP Phones Remotely (DHCP Method)

This topic takes Yealink SIP-T53W (firmware: 96.86.0.81) as an example to describes how to auto provision IP phones in a remote network via Yeastar Onsite Proxy and the DHCP method.

Note: This topic describes how to provision an IP phone and assign a user's extension to the phone. If you want to set up a hot desking phone via auto provisioning, see Set up a Hot Desking Phone.

Requirement

The firmware version of Yeastar P-Series Software Edition is 83.22.0.134 or later.

Scenario

IP phone is deployed in a different network from Yeastar P-Series Software Edition, and the subnet where the IP phone is located has an Onsite Proxy and one DHCP server deployed.

Prerequisites

  • You have deployed an Onsite Proxy in the SAME subnet as the remote IP phones, and connected the Onsite Proxy to the PBX. For more information, see Onsite Proxy Overview.
  • Make sure that there is only one DHCP server in the network where the IP phone is located, otherwise the IP phone may fail to obtain an IP address.
  • IP Phone MUST support DHCP provisioning. For more information, see Auto Provisioning - Supported Devices.
  • You have obtained information of IP phone, including its vendor, model, and MAC address.
  • Make sure that you have downloaded the template for the desired phone model on the PBX (Path: Auto Provisioning > Resource Repository > Default Templates).

Procedure

Step1. Generate configuration file for an IP phone on the PBX

Step2. Set up a DHCP option 66

Step1. Generate configuration file for an IP phone on the PBX

  1. RESET the phone if it is previously used.
  2. Log in to PBX web portal, go to Auto Provisioning > Phones.
  3. Click Add to add a phone to the PBX.
  4. In the IP Phone section, configure phone information as follows:
    • Vendor: Select a phone vendor.
    • Model: Select a phone model.
    • MAC Address: Enter MAC address of the phone.
  5. In the Options section, configure the following settings.
    • Template: Select a desired template from the drop-down list.
      Note: The template provides configurations except extension assignment. 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 DHCP (Via Onsite Proxy).

      A provisioning server URL is generated automatically and displayed on the web page.

    • Onsite Proxy: Select the Onsite Proxy deployed on the subnet where the phone is located.
  6. In the Assign Extension section, assign an extension to the phone.
    Tip: If your desired extension is not listed in the drop-down list, you can check if the extension has been associated with other IP phone or gateway.
  7. Click Save.

Step2. Set up a DHCP option 66

For most firewalls or routers, the built-in DHCP server does not have the capability to add or change the scope option. Tftpd32 software supports this function, which can be an alternative choice to accomplish this task. The following instructions are based on the Tftpd32 DHCP server.

  1. On Yeastar PBX, obtain the provisioning link.
    1. Log in to PBX web portal, go to Auto Provisioning > Phones, click beside the desired IP phone.
    2. In the Options section, copy the provisioning link.

  2. On DHCP server, set up Option 66 using the provisioning link.
    1. Run the Tftpd32 software, click Settings at the bottom of the window.

    2. In the pop-up window, click GLOBAL tab, select the checkbox of DHCP Server.

    3. Click DHCP tab, configure the DHCP server parameters.

      • IP pool start address: The starting IP addresses to be allocated.
      • Size of pool: Total number of available IP addresses.
      • Lease time: IP address lease time.
      • Def. Router (Opt 3): The gateway IP address. In this example, enter 192.168.66.1.
      • Mask (Opt 1): Subnet mask that corresponds to the available IP address segment.
      • DNS Server (Opt 6): DNS server address for the DHCP server. In this example, enter 192.168.66.1.
      • Additional Option: Enter option to 66 and paste the PBX provisioning link besides the option.
    4. Click OK.

      The PC starts to work as a DHCP server.

  3. Restart the IP phone.

Result

  • The IP phone obtains a IP address and provisioning link from the DHCP server, and automatically downloads the configuration file via the provisioning link to achieve Auto Provisioning.

  • The extension is successfully registered on the IP phone via the Onsite Proxy, and the registration status of the IP phone is displayed on Auto Provisioning > Phones.

    • : The assigned extension is registered on the phone.
    • : The assigned extension is unregistered on the phone.
