When starting, most Avaya IP phones go through a process of requesting various files from a file server:
Usually this starts with a request an upgrade file. That file will indicate what firmware the phone should be running. If this differs from the firmware it is running, it will add the software files listed to those it will download. The last line of the upgrade file tells the phone the name of settings file it should request.
The phone requests a settings file. This passes a large number of configuration settings to the phone. It may also list additional files that the phone should request such as language files and screen savers.
The phone requests additional files:
Any firmware files indicated by the upgrade file.
Any additional files indicated by the settings file.
Any additional settings files.
The phone can also request a user settings file.
The above is just a general summary. Depending on the phone, the order of file request may vary. In addition, if requesting firmware for an upgrade, the phone may not request other files until the firmware upgrade has been completed and it has restarted.
When the IP Office system is used as the file server, it has the ability to auto-generate many of the files requested by the phone.
