Once the remote reboot process is initiated on the phone via the Notify message,
the following actions take place:
1.
If the phone is currently in an idle state, the phone will wait 20 seconds and
then contact the TFTP server for the syncinfo.xml file. If the phone is not in
an idle state, the phone will wait until it is in an idle state for 20 seconds and
then contact the TFTP server for the syncinfo.xml file.
2.
The phone reads the syncinfo.xml file and performs the following as
appropriate:
a.
Determines whether the current image is specified. If so, the phone
proceeds to c. If not, the phone proceeds to b.
b.
Determines whether there is a wildcard entry (*) in the image version
parameter. If so, the phone proceeds to c. If not, the phone proceeds to d.
c.
Determines if the sync value is different than what is stored on the phone.
If so, the phone proceeds to e. If not, the phone proceeds to d.
d.
The phone does nothing.

The phone reboots.
The phone the performs a normal reboot process as described in
“Initialization Process Overview” section on page 2-1, sees the new
