Verifying Phone Startup
After receiving power and network connectivity, the phone executes a boot-up sequence.
During this sequence, phones with screens display the Cisco logo and then “Initializing
Network.” All of the lights on the phone will flash.
After your phone is successfully connected to the network and receives a basic configuration,
the extension number appears on the display screen (on models with a display screen) and the
phone has a dial tone.
The phone displays the standard menu for the phone. The date, name and number of the phone
display on the top line of the LCD screen. At the bottom of the LCD screen, softkeys are
displayed over their associated soft buttons.
If the phone does not start, confirm your installation and connections. If these are correct, try
unplugging the phone and plugging it back in again. If you still don’t see the display, then
contact your phone administrator or 8x8 Support.
