Obtaining the Address of Provisioning Server

Yealink IP phones support obtaining the provisioning server address from the PNP server.

The phone broadcast the PNP Subscribe message to obtain a provisioning server

address during bootup. To use Plug and play, make sure this feature is enabled.

To configure the PNP via web user interface:

1. Click on Upgrade ->Advanced.

2. Select Enabled from the pull-down list of PNP config.

Any PNP server activated in the network responses with a SIP NOTIFY message and an

address of the provisioning server contained in the message body. The phone can then

link to the provisioning server and performs the provisioning process.
