Description Parameter
A random delay following the boot-up sequence before performing the reset, specified
in seconds. In a pool of IP Telephony devices that are scheduled to simultaneously
power up, this introduces a spread in the times at which each unit sends a resync request
to the provisioning server. This feature can be useful in a large residential deployment,
in the case of a regional power failure.
The value for this field must be an integer ranging between 0 and 65535.
• In the phone configuration file (cfg.xml) with XML , enter a string in this format:
<Resync_Random_Delay ua="na">2</Resync_Random_Delay>
• On the phone web page , specify the time in seconds between 0 and 65535 for
the phone to delay resync after power-up or reset.
The default value is 2.
Resync Random
Delay
The time (HHmm) that the phone resynchronizes with the provisioning server.
The value for this field must be a four-digit number ranging from 0000 to 2400 to
indicate the time in HHmm format. For example, 0959 indicates 09:59.
• In the phone configuration file (cfg.xml) with XML , enter a string in this format:
<Resync_At__HHmm_ ua="na">0959</Resync_At__HHmm_>
•
On the phone web page
, specify the time in HHMM format for the phone to
start resync.
The default value is empty. If the value is invalid, the parameter is ignored. If this
parameter is set with a valid value, the
Resync Periodic
parameter is ignored.
Resync At (HHmm)
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
resynchronizes 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.
• In the phone configuration file (cfg.xml) with XML , enter a string in this format:
<Resync_At_Random_Delay ua="na">600</Resync_At_Random_Delay>
• On the phone web page , specify the time period in seconds.
The valid value ranges between 0 and 65535.
This feature is disabled when set to zero. The default value is 600 seconds (10 minutes).
