Requirements
In order to perform as SIP endpoints in your network successfully, you need the following in deployments:
l
A working IP network is established.
l
VoIP gateways configured for SIP.
l
The latest (or compatible) firmware of IP phones is available.
l
A call server is active and configured to receive and send SIP messages.
l
A text editor, such as +, to create and edit boot files, configuration files and resource files.
Initialization Process Overview
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 ini-
tialization process.

Downloading the Resource Files
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 you connect the IP phone to a switch, the switch notifies the IP phone of the VLAN information defined on the
switch (if using LLDP). The IP phone can then proceed with the DHCP request for its network settings (if using DHCP).
Querying the DHCP (Dynamic Host Configuration Protocol) Server
The IP phone is capable of querying a DHCP server.
After establishing network connectivity, the IP phone can obtain the following network parameters from the DHCP
server during initialization:
