Scenarios

The provisioning methods and operations vary depending on the network environment of NEC IP Phone and Yeastar PBX.

Auto provision an NEC IP phone in the local network
Auto provision an NEC IP phone in a remote network

Auto provision an NEC IP phone in the local network

In this scenario, you can provision the NEC IP phone by using a third-party DHCP server to deliver a PBX-provided provisioning link to the IP phone. This allows the phone to retrieve configurations from the PBX using the given link.

Prerequisites

Set up a DHCP server in the same subnet as the IP phone to assign it an IP address.

Note: Make sure that there is only one DHCP server running in the subnet, or the IP phone would fail to obtain an IP address.
RESET the IP phone if it is previously used.
Gather information of IP phone, including Vendor, Model, and MAC address.
Make sure that you have downloaded the template for the desired phone model (Path: Auto Provisioning > Resource Repository > Default Templates).
If the IP phone and PBX are located in different subnets, make sure the following conditions are met:
- The two subnets can communicates with each other.
- Enable the Remote Registration feature for the extension to be assigned to the IP phone (Path: Extension and Trunk > Extension > > Security > SIP Security > Allow Remote Registration).

Procedure

Step 1. Add the NEC IP phone on PBX
Step 2. Configure DHCP option 66 on DHCP server

Step 1. Add the NEC IP phone on PBX

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

Log in to PBX web portal, go to Auto Provisioning > Phones.
Click Add > Add.
In the IP Phone section, enter the following phone information.
- Vendor: Select NEC.
- Model: Select the phone model. In this example, select DT900 ITK-12D-1P.
- MAC Address: Enter the MAC address of the IP phone.
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 DHCP (In the Office).
  A provisioning link is automatically generated and displayed in the Provisioning Link field. This provisioning link points to the location where the phone's configuration file is stored.
  
  Note: Note down the provisioning link, as you will use it later.
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.
- To release the extension from the associated IP phone or gateway, see Release an Extension from a Provisioned IP Phone/Gateway.
- To assign the extension to the phone without releasing it from the previously associated device, you can configure the concurrent registration setting for the extension, as the PBX only allows an extension to register with one SIP endpoint by default.
Click Save.
The IP phone is added and displayed in the Auto Provisioning phone list.

Step 2. Configure DHCP option 66 on DHCP server

On the DHCP server, configure DHCP option 66 with the provisioning link obtained from the PBX.

The following instructions take Tftpd64 DHCP server as an example to show how to configure the option 66.

On the running Tftpd64 software, go to Settings > DHCP > DHCP Options.
Add option 66 and define the location of the configuration files.
1. In the Additional Option field, enter 66.
2. In the string value field, enter the provisioning link obtained from the PBX.
Click OK to save the settings.

Results

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.

Auto provision an NEC IP phone in a remote network

In this scenario, you can use the public IP address / external host domain name of the PBX to provision an IP phone. By configuring a third-party DHCP server to deliver a PBX-provided provisioning link to the IP phone, the phone can retrieve configurations from the PBX using the given link.

Important: Due to NEC phone limitations, if using an external host domain name, the length of the domain name must NOT exceed 17 characters (excluding the prefix https://). Otherwise, the provisioning will fail.

Prerequisites

Set up a DHCP server in the same subnet as the IP phone to assign it an IP address.

Note: Make sure that there is only one DHCP server running in the subnet, or the IP phone would fail to obtain an IP address.
RESET the IP phone if it is previously used.
Gather information of IP phone, including Vendor, Model, and MAC address.
Make sure that you have downloaded the template for the desired phone model (Path: Auto Provisioning > Resource Repository > Default Templates).
Make sure that you have completed the corresponding settings on PBX:
- Configure PBX network for remote access by a public IP address or by an external host domain name.
- Complete the following settings for the extension to be assigned to the IP phone:
  - Enable NAT for the extension (Path: Extension and Trunk > Extension > > Advanced > VoIP Settings > NAT).
  - Enable the Remote Registration feature for the extension (Path: Extension and Trunk > Extension > > Security > SIP Security > Allow Remote Registration).

Procedure

- 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 (Remote).
  A provisioning link is automatically generated and displayed in the Provisioning Link field. This provisioning link points to the location where the phone's configuration file is stored.
  
  Note: Note down the provisioning link, as you will use it later.

Click Save.
The IP phone is added and displayed in the Auto Provisioning phone list.

Step 2. Configure DHCP options on DHCP server

On the DHCP server, configure DHCP option 42 and option 66.

The following instructions take Tftpd64 DHCP server as an example to show how to configure the options.

On the running Tftpd64 software, go to Settings > DHCP > DHCP Options.
Configure the following DHCP options.
- NTP server (Opt 42): Enter the IP address of an NTP server.
- Additional Option: Enter 66, then enter the provisioning link obtained from the PBX.
Click OK to save the settings.

Results

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.
