Deskphone Initialization Process Overview
These steps offer a high-level description of the information exchanged when the deskphone
initializes and registers. This description assumes that all equipment is properly administered
ahead of time. Installing and Maintaining Avaya 9601/9608/9608G/9611G/9621G/9641G IP
Deskphones SIP provides a detailed description of initialization (power-up and reset).
Step 1: Accessing the network
The deskphone is appropriately installed and powered. After a short initialization process, the
deskphone displays the speed at which it is connected to the network and determines whether
to initiate 802.1X network access procedures.
Step 2: DHCP processing
If an IP address has not been manually configured in the deskphone, the deskphone initiates
DHCP, as described in
Administering the DHCP and File Servers on page 43. For a list of all the
parameters that you can set via DHCP, see
Parameters set by DHCP in a site-specific
option on page 45.
Step 3: Downloading files
The Deskphones can download configuration files, certificate files, and language files from
either an HTTP or HTTPS server but they can only download software files from an HTTP
server. When the deskphone boots, the deskphone first downloads an upgrade configuration
file. The upgrade configuration file specifies the deskphone which software files the deskphone
should use. The deskphone then downloads a settings configuration file. Based on the settings
in the configuration file, the deskphone may then download language files and/or certificate
files. Finally, the deskphone downloads one or two new software files, depending on whether or
not the software in the deskphone is the same as that specified in the upgrade file. For more
information about this download process and settings file, see.
