Notes:

Additional Override DHCP Option

Allow users to configure additional DHCP Options to be used for the firmware server instead of the configured firmware server or the server from DHCP Options 43 and 66. It can be set to None or Option 150, it is set to None by default.

3CX Auto Provision

Default is No. If set to Yes, phone will multicast SUBSCRIBE for provision if this feature is enabled.

Enable using tags in URL

Allows users to configure variables on the configuration server path to differentiate the directories on the server.

Example: When provisioning, a user can define the mac address and IP address when sending the HTTP Send request link in the following form “192.168.5.96:8060/?mac=[MAC]&lan_ip=[IP]”, the link will look like this example:http://192.168.5.99/mac=000b89a9064&lan_ip=192.168.5.99/cfg.xml

There are three options to choose from: “Always Check for New Firmware”, “Check New Firmware only when F/W pre/suffix changes”, and “Always Skip the Firmware Check”.

Download and Process All Available Config Files

By default, the device first provisions cfgMAC, then attempts to provision the first available configuration file in the following order: DHCP Option 67 boot file (cfgdhcpopt67.xml) → cfgMAC.xml → cfgProductModel.xml → cfg.xml (corresponding to the Option 67-specific, device-specific, model-specific, and global configuration files).

When this option is enabled, the device downloads and processes all available configuration files in the following order: cfg.xml → cfgProductModel.xml → cfgMAC.xml → cfgMAC → cfgMAC_override.xml → DHCP Option 67 boot file (cfgdhcpopt67.xml). Each configuration file is applied sequentially, and settings in later configuration files overwrite those applied by previously processed configuration files.

Disabled by default
