Unified upgrade
When an IP phone is powered on or restarted, it obtains the version file URL from the
DHCP server, and compares the version file that is stored on the file server and its own
version. If the versions are different, the IP phone automatically upgrades and starts. If
the versions are the same, the IP phone starts normally.
Centralized configuration
When an IP phone is powered on or restarted, it obtains the configuration file URL from
the DHCP server, and compares the configuration in the configuration file that is stored
on the file server and its own configuration. If the configurations are different, the IP
phone automatically upgrades and starts. If the configurations are the same, the IP phone
starts normally.
4.2.1 Preparations for Configuration and Upgrading IP Phones
To configure and upgrade IP phones in batches during the deployment, prepare the following
items:
Configuration file template
The configuration template is an .xml file. You can change the parameter values in the
template based on the site scenarios.
File server
The HTTP server is used.
DHCP server
When configuring the DHCP server, define a Option248 parameter as the file server
URL. After this parameter is set, the DHCP server sends the file server URL to the IP
phone that applies for an IP address. The phone downloads the version files and
configuration file from this URL.
DNS server
A DNS server is required when you use domain names to configure the configuration file
URL.
Version software
The version software is not required if you only want to configure IP phones in batches.
