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 extension(s) to the phone, then specify which extension's phonebook and function keys you want to use on the phone.
Tip: If your desired extension is not listed in the drop-down list of the Extension column, it indicates that the devices registered to the extension has reached the limit. You can use either of the following methods to proceed.
- To release the extension from the associated IP phone or gateway, see Release an Extension from a Provisioned IP Phone/Gateway.
- To raise the phone registration limit, you need to configure the concurrent registration setting for the extension, as the PBX only allows an extension to register with one SIP endpoint by default.
- To assign a single extension to the phone, select a desired extension from the drop-down list beside SIP1.
  Both the Phonebook Line and Function Key Line fields are set to SIP1 by default, indicating that the phone will use the authorized phonebook(s) and function keys of the extension assigned to the SIP line 1.
- To assign multiple extensions to the phone, complete the following settings.
  1. In the drop-down list beside SIP1, select a desired extension for SIP line 1.
  2. Click Add, then select a desired SIP line and an extension for the added entry.
    To assign more extensions to the phone, repeat this step.
    Note: The selected SIP lines must be supported by the phone, otherwise the configurations for unsupported SIP line will not be applied. You can check the phone's supported SIP lines via the phone webpage or on the device screen.
  3. In the Phonebook Line drop-down list, select a SIP line. The phone book of extension assigned to the SIP line will be applied to the phone.
    Note: After successful registration, contacts are available regardless of which SIP line is currently active on the phone.
  4. In the Function Key Line drop-down list, select a SIP line. The function keys of extension assigned to the SIP line will be applied to the phone.
    Note: After successful registration, the function keys take effect only when the selected SIP line is active on the phone.
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.
Note: If the status displays , this indicates that you assigned multiple extensions to the IP phone but only some of them are successfully registered on the phone. You can hover over to view the registration status of each extension.
If multiple extensions are successfully registered on the phone, corresponding SIP lines are associated with different physical line keys on the device.
You can press a line key to activate the target SIP line. The corresponding indicator LED illuminates, and all calls are processed over this SIP line.

Auto provision an NEC IP phone in a remote network

In this scenario, you can use the public IP address / 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 a 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, by an external host domain name or by a Yeastar domain name.
  Important: The following PBX ports MUST be forwarded for RPS provisioning.
  - RTP ports
  - SIP port
  - Web Server port
- 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).
