5.3 Updating Software on the ZIP4x4
5.3.1 Introduction
You must connect the phone to a LAN that has a TFTP server and a DHCP server.
1
The DHCP
server provides an IP address to the phone and also the address of the TFTP server. The phone
accesses the TFTP server to locate and retrieve its configuration files. It reads the configuration
files to identify what software version it should be using. If the files specify a different version
from that on the phone, the phone retrieves the specified software version from the TFTP server.
5.3.2 Specific Description
To update the software, one or both of the configuration files described in section 5.2 must specify
the software version that the phone must use. This is specified on the line shown in figure 5-2 as:
software_version=0.1.4
The phone compares the version specified to that installed on the phone. If the versions are the
same, the phone continues with the startup process. If the versions are different, the phone
retrieves the software from the TFTP site. The phone looks first in the root directory of the TFTP
site then in the subdirectory of the TFTP site where the specific configuration file may be stored,
if one is specified.
The software name is:
ZIP4x4_<version>.bin
For example:
ZIP4x4_0_1_4.bin
The file name uses the underscore character to separate the three parts of the software version
number.
