After your phone is powered on, the system boots up and performs the following steps:
Automatic Phone Initialization
The phone finishes the initialization by loading the saved configuration. The LCD screen
displays “Initializing, Please wait” during this process.
DHCP (Dynamic Host Configuration Protocol)
The phone attempts to contact a DHCP server in your network to obtain valid network
settings (e.g., IP address, subnet mask, default gateway address and DNS address) by
default.
Note
You can view the system status of your phone via phone user interface or web user
interface.

subnet).


MAC address and device certificate status).

Account status (e.g., the register status of SIP accounts).
