Firmware and Configuration Files
Description
When the IP phone is initialized for the first time, DHCP is enabled by default.
Depending on the type of configuration server setup you may have, the IP phone
may download a firmware version and configuration files automatically, or you
may need to download it manually.
The firmware consists of a single file called:
• <phone model>.st
The configuration files consist of two files called:
• aastra.cfg
•<mac>.cfg
The following table provides the firmware for each Aastra IP phone model.
Note: Automatic download is dependant on your configuration server
setup.
