Yealink VP59 Auto Provisioning Manual page 43

When the IP phone obtains a provisioning server URL containing the wildcard $PN, it
automatically replaces the character $PN with the value of the parameter
"static.auto_provision.url_wildcard.pn" configured on the IP phone. When the IP phone is
triggered to perform auto provisioning, it will request to download the boot files and
configuration files from the identified directory on the provisioning server.
The value of the parameter "
accordance with the directory name of the provisioning server directory where the boot files and
configuration files of the IP phones are located.
The following example assists in explaining the wildcard feature:
You want to deploy SIP-T42G and SIP-T46G IP phones simultaneously in your environment. IP
phones are configured to obtain the provisioning server URL via DHCP option 66. The following
details how to deploy the SIP-T42G and SIP-T46G IP phones using wildcard feature.
Create two directories on the root directory of provisioning server.
1.
Configure the directory names of these two directories to be "T42G" and "T46G".
2.
Place the associated boot files and configuration files to the directory created above.
3.
Configure the value of DHCP option 66 on the DHCP server as: tftp://192.168.1.100/$PN.
4.
Configure the value of the parameter "static.auto_provision.url_wildcard.pn".
5.
The default value of the parameter "static.auto_provision.url_wildcard.pn" is ''T42G'' for the
SIP-T42G IP phones and ''T46G'' for the SIP-T46G IP phones. If the default value is different
from the directory name, you need to configure the value of this parameter to be the
directory name on the IP phones in advance.
During startup, IP phones obtain the provisioning server URL "tftp://192.168.1.100/$PN" via
DHCP option 66, and then replace the character "$PN" in the URL with "T42G" for the SIP-T42G
IP phones and "T46G" for the SIP-T46G IP phones. When performing auto provisioning, the
SIP-T42G IP phones and the SIP-T46G IP phones first request to download the MAC-Oriented
boot files and configuration files referenced in MAC-Oriented boot files from the provisioning
server address "tftp://192.168.1.100/T42G" and "tftp://192.168.1.100/T46G" respectively. If no
matched MAC-Oriented boot files are found on the server, the SIP-T42G IP phones and the
SIP-T46G IP phones request to download the common boot files and configuration files
referenced in common boot files from the provisioning server address
"tftp://192.168.1.100/T42G" and "tftp://192.168.1.100/T46G" respectively.
If the URL is configured as "tftp://192.168.1.100/$PN/$MAC.boot" on the DHCP server, the
SIP-T42G IP phones and the SIP-T46G IP phones will replace the characters "$PN" with "T42G"
and "T46G" respectively, and replace the characters "$MAC" with their MAC addresses. For
example, the MAC address of one SIP-T42G IP phone is 00156543EC97. When performing auto
provisioning, the IP phone will only request to download the 00156543ec97.boot file and
configuration files referenced in the 00156543ec97.boot file from the provisioning server
address "tftp://192.168.1.100/T42G".
