IP Phone Administrator Guide
Firmware and Configuration Files
Description
When the IP phone is initialized for the first time, DHCP is enabled by default
allowing the phone to automatically get its IP address from the network. Upon
bootup, the phone also automatically updates it firmware and configuration files
from the configuration server using the default TFTP protocol.
The IP Phones support TFTP, FTP, HTTP, and HTTPS as download protocols.
You can change the protocol server that you use to download firmware and
configuration files, and can perform the download manually or configure the
phone to download them automatically.
The firmware consists of a single file called:
• <phone model>.st (for example, 55i.st (for 6755i)) - This file contains
information about the specific IP Phone model and contains the language
packs to load to the phone.
The configuration files consist of two files called:
• aastra.cfg - This file contains configuration information about the IP Phone.
• <MAC>.cfg (for example, 00085D1610DE.cfg) - This file contains
configuration information about the IP Phone.
Note: Automatic download is dependant on your configuration server
setup. For more information about manual and automatic download of
firmware, see Chapter 8, “Upgrading the Firmware.” For more
information on changing the download protocol on your phone, see
Chapter 4, the section, “Configuring the Configuration Server Protocol”
on page 4-108.
