1. The device loads the configuration settings stored on the flash memory. These settings are either the
factory default settings or the settings that were previously changed when restarting.
2. The device checks if the provisioning URL setting has been changed manually either by web programming
or phone programming.
If it has been changed manually, go to step 8.
If it has not been changed manually, go to the next step.
3. If SIP PnP is enabled, the device sends a multicast SIP SUBSCRIBE message. The device waits for a
response and then checks whether a SIP NOTIFY reply is received that contains the provisioning URL
setting in the body of the message.
If a valid SIP NOTIFY is received, go to step 8.
If a valid SIP NOTIFY is not received, go to the next step.
4. If DHCP option 160 is enabled, the device checks whether DHCP option 160 has been received.
If it has been received, go to step 8.
If it has not been received, go to the next step.
5. If DHCP option 159 is enabled, the device checks whether DHCP option 159 has been received.
If it has been received, go to step 8.
If it has not been received, go to the next step.
6. If DHCP option 66 is enabled, the device checks whether DHCP option 66 have been received.
If it has been received, go to step 8.
If it has not been received, go to the next step.
7. If none of the above steps could be applied, the device sends an HTTP request to the Panasonic redirection
server.
If successful, go to step 8. If it fails, go to step 9.
8. The device attempts to download the initial configuration file.
If it can be downloaded, the device downloads the device configuration file.
If it cannot be downloaded, go to the next step.
9. The device checks whether there are any locally saved configuration files.
If there are locally saved configuration files, the settings are applied.
If there are no locally saved configuration files, provisioning has failed.
The device will try provisioning again according to the interval specified by the CFG_RTRY_INTVL
parameter.
