Parameter Name
Resync_At_Random_Delay
(firmware v7.4.9c and higher)
Resync_Periodic
Description and Default Value
Prevents an overload of the provisioning
server when a large number of devices
power-on simultaneously.
To avoid flooding resync requests to the
server from multiple phones, the phone
resyncs in the range between the hours and
minutes, and the hours and minutes plus the
random delay (hhmm,
hhmm+random_delay). For example, if the
random delay = (Resync_At_Random_Delay
+ 30)/60 minutes.
The input value in seconds is converted to
minutes, rounding up to the next minute to
calculate the final random_delay interval.
This feature is disabled when this
parameter is set to zero. The default value is
600 seconds (10 minutes). If the parameter
value is set to less than 600, the default
value is used.
The time interval between periodic resyncs
with the provisioning server. The associated
resync timer is active only after the first
successful sync with the server.
Set this parameter to zero to disable
periodic resyncing.
The default value is 3600 seconds.
