Yealink IP Phones Auto Provisioning Guide

The parameter “auto_provision.url_wildcard.pn” is used to configure the directory name
the configuration files located. For more information on the parameter, refer to
. For W56P, refer to

Configuration Parameters in CFG Files.xlsx
.
When the IP phone obtains a provisioning server URL containing the wildcard $PN, it
automatically replaces the character $PN with the value of the parameter
“auto_provision.url_wildcard.pn” configured on the IP phone. When the IP phone is
triggered to perform auto provisioning, it will request to download the configuration files
from the identified directory on the provisioning server.
The following example assists in explaining the wildcard feature:
You want to deploy SIP-T42G and SIP-T46G IP phones simultaneously in your environment.
IP phones are configured to obtain the provisioning server address via DHCP option 66.
The following details how to deploy the SIP-T42G and SIP-T46G IP phones using wildcard
feature.
1.
Create two directories on the root directory of provisioning server.
2.
Configure the directory names of these two directories to be “T42G” and “T46G”.
3.
Place the associated configuration files to the directory created above.
4.
Configure the value of DHCP option 66 on the DHCP server as:
tftp://192.168.1.100/$PN.
5.
Configure the value of the parameter “auto_provision.url_wildcard.pn”.
The default value of the parameter “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 request to download
configuration files (<MAC>.cfg files, y000000000029.cfg for the SIP-T42G IP phones, and
y000000000028.cfg for the SIP-T46G IP phones) 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.cfg” 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
The value of the parameter “auto_provision.url_wildcard.pn” must be configured in
accordance with the directory name of the provisioning server directory where the
configuration files of the IP phones are located.
