c) Edit the parameters in the file as desired.
2. Create new common configuration files by performing the following steps:
a) Create <y0000000000xx>.cfg files by using the Common CFG file from the
distribution as templates.
b) Edit the parameters in the file as desired.
3. Copy configuration files to the home directory of the provisioning server.
4. Reboot IP phones to trigger the auto provisioning process.
IP phones discover the provisioning server address, and then download the
configuration files from the provisioning server.
For more information on configuration files, refer to
protecting against unauthorized access, you can encrypt configuration files. For more
information on encrypting configuration files, refer to
page 224.
During the auto provisioning process, the IP phone supports the following methods to
discover the provisioning server address:
Zero Touch: Zero Touch feature guides you to configure network settings and the

provisioning server address via phone user interface after startup. (Zero Touch is
only applicable to SIP-T22(P) IP phones.)
PnP: PnP feature allows IP phones to discover the provisioning server address by

broadcasting the PnP SUBSCRIBE message during startup.
DHCP: DHCP option can be used to provide the address or URL of the provisioning

server to IP phones. When the IP phone requests an IP address using the DHCP
protocol, the resulting response may contain option 66 or the custom option (if
configured) that contains the provisioning server address.
Static: You can manually configure the server address via phone user interface or

web user interface.
For more information on the above methods, refer to Yealink IP Phones Auto Provisioning
Guide, available online:
