Phone Initialization
The initialization process of the IP phone is responsible for network connectivity and operation of the IP phone in
your local network.
Once you connect your IP phone to the network and to an electrical supply, the IP phone begins its initialization
process.
During the initialization process, the following events take place:
Automatic Phone Initialization
The phone finishes the initialization by loading the saved configuration. The touch screen displays “Welcome
Initializing…please wait” during this process.
In the background, the IP phone executes the following steps:
Loading the ROM file
The ROM file resides in the flash memory of the IP phone. The IP phone comes from the factory with a ROM file
pre-loaded. During initialization, the IP phone runs a bootstrap loader that loads and executes the ROM file.
Configuring the VLAN
If the IP phone is connected to a switch, the switch notifies the IP phone of the VLAN information defined on the
switch (if using LLDP or CDP). The IP phone can then proceed with the DHCP request for its network settings (if
using DHCP).
DHCP (Dynamic Host Configuration Protocol)
The IP phone is capable of querying a DHCP server. DHCP is enabled on the IP phone by default. The phone
attempts to contact a DHCP server in your network to obtain valid IPv4 and IPv6 network settings (for example, IP
address, subnet mask, default gateway address and DNS address) by default.
• Basic network pre-configuration may be required to use the IP phone using DHCP. For more details,
refer
“DHCP” .
• You need to configure network parameters of the IP phone manually if any of them is not supplied by
the DHCP server. For more information on configuring network parameters manually, refer
“Configuring
Network Parameters Manually” .
Contacting the provisioning server
If the IP phone is configured to obtain configurations from the provisioning server, it will connect to the provisioning
server and download the configuration file(s) during startup. The IP phone will be able to resolve and update
configurations written in the configuration file(s). If the IP phone does not obtain configurations from the
provisioning server, the IP phone will use configurations stored in the flash memory.
