Phone Initialization 
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 
“Welcome Initializing…Please wait” during the initialization. 
DHCP (Dynamic Host Configuration Protocol) 
The phone attempts to contact a DHCP server in your network to obtain valid IPv4 network 
settings (e.g., IP address, subnet mask, default gateway address and DNS address) by default. 
Note 
Phone Status 
You can view phone status via phone user interface or web user interface. 
Available information of phone status includes: 
  Network status (IPv4 status or IPv6 status, IP mode and MAC address). 
-  IPv4 uses a 32-bit address. 
-  IPv6 is an updated version of the current Internet Protocol to meet the increased 
demands for unique IP address, using a 128-bit address. 
  Phone status (product name, hardware version, firmware version, product ID, MAC address 
and device certificate status). 
  Account status (register status of SIP accounts). 
To view the phone status via phone user interface: 
1.  Press          , or press Menu->Status. 
2.  Press          or          to scroll through the list and view the specific information.
