Provisioning the Phone
5.1 Introduction
This and the following two sections (section 5.2 and section 5.3) describe the method used by the
ZIP4x4 to automatically obtain its configuration. These sections describe the underlying method
for the exchanges that take place. You do not need to read these sections unless you want to
understand the provisioning process, or make the ZIP4x4 work with a particular SIP system.
5.1.1 Summary of Boot Process
To use the ZIP4x4 in its usual manner, you must connect the phone to a LAN that has a DHCP
server and a TFTP server. The start up process is as follows:
1. The DHCP server provides an IP address to the phone and also the address of the TFTP
server.
2. The phone accesses the TFTP server to locate a configuration file that is common for all
ZIP4x4 phones connected to your network.
3. The phone reads the common configuration file. The configuration file points to a directory
where the phone can find its specific configuration file.
4. The phone reads its specific configuration file.
5. The phone uses the data retrieved from the configuration files to configure itself so that it
can operate properly in the network.
5.1.1.1 DHCP Support

with the following options for your network to fully support the ZIP4x4:
