Normally, many phone models may be deployed in your environment. To deploy many
phone models using a unified provisioning server, it is convenient for the administrator
to configure a unified provisioning server URL for different phone models. On the
provisioning server, many directories need to be configured for different phone models,
each with a unique directory name. Yealink IP phones support the following wildcards in
the provisioning server URL:

$PN: it is used to identify the directory name of the provisioning server directory
where the corresponding configuration files are located

$MAC: it is used to identify the MAC address of the IP phone.
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
Description of Configuration Parameters in CFG Files on page 81 .
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
