according to the option 43 sent by the DHCP server.
● The upgrade mode and server path of the configuration upgrade mode will also be
set according to option 160 and 66 sent by the DHCP server
If set to "Prefer, fallback when failed", the device can fallback to use the configured

the DHCP Option fails.
Configures the phone to allow the DHCP offer message to override the Config Server
Path via the Option 120 header. The default setting is "Yes".

issued by the local DHCP in Option 242 to configure proxy, transport protocol and
server path. The default setting is "Yes".
Config Provision
By default, the device will provision the first available config in the order of cfgMAC,
cfgMAC.xml, cfgMODEL.xml, and cfg.xml(corresponding to device specific, model
specific, and global configs). If set to "Yes", the device will download and apply
(override) all available configs in the order of cfgMAC, cfgMAC.xml, cfgMODEL.xml,
cfg.xml.
This feature's purpose is to make the device downloads the configuration files and
provision by the configured order.

allow itself to be discovered and be configured by the SIP platform. If it is set to "User
Type A', the phone will broadcast the mDNS message "A_grandstream-cfg.local"; if it
is set to "Use Type SRV", the mDNS message will be "SRV_grandstream-cfg.local".
