By default many Avaya SIP phones poll their configured file server hourly to check for new or changed files. This applies to H175, J100 Series and Vantage K100 Series phones. This allows the phones to download new settings without being restarted. They can also download new firmware and then automatically upgrade.

The 46xxsettings.txt file can be edited to include settings to control the frequency of polling and set when phones will automatically upgrade if not rebooted. Refer to the relevant administrators manual for the phone series for details of the available settings.
