Auto Provisioning Overview

Auto Provisioning is a time-saving feature that helps you to manage and deploy IP phones and gateways centrally on Yeastar P-Series PBX System. The process of configuring and managing IP phones and gateways is simplified, which makes deployment and management of devices fast and convenient.

Auto Provisioning supported devices

Yeastar P-Series PBX System supports various models for Auto Provisioning.

Auto Provisioning methods

Yeastar P-Series PBX System supports three Auto Provisioning methods, you can select a method to provision your IP phones and gateways according to your network environment.

PnP (Plug and Play)
PnP method supports auto provisioning IP phones and gateways that are located in the same LAN subnet as the PBX.

For more information, see Auto Provision IP Phones in Local Network (PnP Method) and Auto Provision Yeastar TA FXS Gateways (PnP Method).

DHCP Option 66
DHCP method supports auto provisioning IP phones and gateways that are located in the same local network as the PBX (same LAN subnet or different LAN subnet).
Note: Snom IP phones do not support DHCP Auto Provisioning method.

For more information, see Auto Provision IP Phones in Local Network (DHCP Method) and Auto Provision Yeastar TA FXS Gateways (DHCP Method).

RPS
RPS method supports auto provisioning remote IP phones via public IP address or Yeastar FQDN.
Note: The Yeastar TA FXS gateway does not support RPS Auto Provisioning method.

For more information, see Auto Provision IP Phones Remotely (RPS Method) and Auto Provision IP Phones Remotely (RPS FQDN Method).

Note: In practice, the actual implemented Auto Provisioning method of IP phone/gateways does not limit to your selected method. The followings shows the detailed information.
  • When you select PnP Auto Provisioning method, the available methods are PnP and DHCP.
  • When you select DHCP Auto Provisioning method, the available methods are PnP and DHCP.
  • When you select RPS Auto Provisioning method, the available methods are PnP, DHCP, and RPS.

How Auto Provisioning works

This section introduces how the three Auto Provisioning methods work with IP phones and the PBX, which can help you understand the operating principle and locate the Auto Provisioning problem rapidly.
PnP Provisioning
  1. When an IP phone boots up, it sends a multicast SIP SUBSCRIBE message to the local network.
  2. The PBX detects the SUBSCRIBE message and replies a SIP NOTIFY to the IP phone, indicating the provisioning server URL.
  3. The IP phone downloads configuration file from the PBX and applies the configurations automatically.
DHCP Provisioning

You can directly use the PBX as a DHCP server, or use a third-party DHCP server that supports DHCP option 66.

Note: The DHCP server in the PBX supports only one DHCP address pool.
Using the PBX as a DHCP server
Using a third-party DHCP server
  1. When an IP phone boots up, it sends DHCP requests to the local network.
  2. The DHCP server assigns an IP address, and indicates the provisioning server URL in DHCP option 66.
  3. The IP phone downloads the configuration file from the provisioning server (PBX), and applies the configuration.
RPS Provisioning

  1. After you add a phone's MAC address to the PBX, the phone's MAC address and provisioning server (PBX) are automatically added to the phone manufacture's RPS server.
  2. When the IP phone boots up, it sends a request to the RPS server, asking for a configuration file.
  3. The RPS server redirects the phone to visit the provisioning server (PBX).
  4. The IP phone downloads its configuration file from the provisioning server (PBX), and applies the configuration.
