When using the IP Office system as the file server, when the phone requests a file, if that file is not available the IP Office system auto-generate a temporary file for the phone.
The settings in an auto-generated file can vary depending on the type of phone requesting the file.
The settings also vary depend on whether the request is from a phone on the same network as the IP Office system or from a remote phone.
The auto-generated files are not cached by the IP Office. The files are generated when requested and deleted after the request.
If an actual file with the same name is uploaded to the system, auto-generation of that particular file stops. See Loading files onto the system.
