Flexible Auto Provision
The IP phone performs auto provisioning at a random time on a random day within a specific
period of time. The random day is calculated on the basis of the phone's MAC address. You can
specify an interval and configure what time of the day to trigger the IP phone to perform auto
provisioning.
For example, you can configure the IP phone to check and update new configuration between 1
and 6 o’clock in the morning at a 30-day interval. The IP phone will perform auto provisioning at
a random time (e.g., 03:47) on a random day (e.g., 18) based on the phone's MAC address.
Note that the update time will be recalculated if auto provisioning occurs (e.g., Auto Provision
Now) during this specific period of time.
To activate the flexible auto provision mode via web user interface:
1. Click on Settings->Auto Provision.
2. Mark the On radio box in the Flexible Auto Provision field.
3. Enter the desired value in the Flexible Interval Days field.
