Plug and Play (PnP) Server 
Yealink IP phones support obtaining the provisioning server address from the PnP server. The IP 
phone broadcasts the PnP SUBSCRIBE message to obtain the provisioning server address during 
startup. To use Plug and Play, make sure this feature is enabled. 
To configure PnP via web user interface: 
1.  Click on Settings->Auto Provision. 
2.  Mark the On radio box in the PNP Active field. 
 
3.  Click Confirm to accept the change. 
Any PnP server activated in the network responses with a SIP NOTIFY message, and an 
address of the provisioning server is contained in the message body. 
 
After the IP phone obtains the provisioning server address from the PNP server, it will connect 
to the provisioning server and perform auto provisioning during startup.
