Auto-Provisioning; Local Devices (Lan); Plug And Play - Grandstream Networks 3CX Configuration Manual

AUTO-PROVISIONING

Before configuring the end device, users will need to ensure that extensions are already created on 3CX
Phone System and make sure that the devices are properly powered up, connected to your Network and
have IP addresses.
This chapter will introduce how to auto-provision a Grandstream device located in the same local Network
as 3CX Phone System, behind a 3CX Session Border Controller, or remotely using STUN.

Local Devices (LAN)

When having the devices on the same network as 3CX Phone System, users have the ability to provision
end devices automatically either using Plug and Play feature, or by adding the device on the 3CX Phone
System.

Plug and Play

Grandstream SIP devices can be provisioned using Plug and Play feature which offers the possibility to be
auto-discovered at boot when in the same Local Network as 3CX Phone System, allowing the phone to
retrieve the configuration automatically once assigned.
To auto-provision Grandstream devices, follow below steps:
1. Power on the phone and connect it to the same LAN as 3CX Phone System.
At booting stage, Grandstream devices send a SIP SUBSCRIBE message to multicast IP address
to be discoverable by 3CX Phone System in same LAN.
2. Access to 3CX Phone System interface and click on Phones in the left panel.
Discovered devices with their related information including Model, MAC address, IP address will
be displayed as shown in below figure.
Note: If a device is not discovered, access to its web interface and set 3CX Auto Provision to
"Yes" (by default set to Yes) under Maintenance  Upgrade and Provisioning then reboot it.
