Parameter Name

Description

Default Value

Provision Enable

Enable or disable the Provision functions.

Enable

Resync On Reset

Triggers a resync after every reboot except for reboot caused by parameter updates and firmware upgrades.

Enable

Resync Random Delay

The maximum value for a random time interval that the device waits before making its initial contact with the provisioning server. This delay is effective only on the initial configuration attempt following device power-on or reset. The delay is a pseudo-random number between zero and this value.

This parameter is in units of 1 seconds; the default value of 40 represents 40 seconds. This feature is disabled when this parameter is set to zero.

This feature can be used to prevent an overload of the provisioning server when a large number of devices power-on simultaneously.

40 seconds

Resync Periodic

The time interval between periodic resyncs with the provisioning server.

Set this parameter to zero to disable periodic resyncing.

3600 seconds

Resync Error Retry Delay

If the last resync was failure, IP542N will retry resync after the "Resync Error Retry Delay" time

3600 seconds

Forced Resync Delay

Maximum delay (in seconds) the VOIP ATA OR IP PHONE waits before performing a resync.

The device does not resync while one of its phone lines is active. Because a resync can take several seconds, it is desirable to wait until the device has been idle for an extended period before resyncing. This allows a user to make calls in succession without interruption.

The device has a timer that begins counting down when all of its lines become idle. This parameter is the initial value of the counter. Resync events are delayed until this counter decrements to zero.

14,400 seconds

Resync After Upgrade

Attempt

Triggers a resync after every firmware upgrade attempt.

Enable

Option 66

Allow or not allow DHCP option 66 to override server.

Yes

Configfile

Configuration file is used for overriding the server

nf

Profile Rule

This parameter is a profile script that evaluates to the provisioning resync command. The command is a TCP/IP operation and an associated URL. The TCP/IP operation can be TFTP, HTTP, or HTTPS.

The file name can have macros, such as $MA, which expands to the device MAC address.

Such as: https://192.168.20.17/param_$nf

Empty

Phone Num1 for config

The first phone number which used to reboot IP542N in remote.

Empty

Phone Num2 for config

The second phone number which used to reboot IP542N in remote.

Empty

Upgrade Enable

Enables firmware upgrade operations independently of resync actions

Enable

Upgrade Error Retry Delay

The upgrade retry interval (in seconds) applied in case of upgrade failure. The device has a firmware upgrade error timer that activates after a failed firmware upgrade attempt. The timer is initialized with the value in this parameter. The next firmware upgrade attempt occurs when this timer counts down to zero.

3600 seconds.

Downgrade Rev Limit

Enforces a lower limit on the acceptable version number during a firmware upgrade or downgrade. The device does not complete a firmware upgrade operation unless the firmware version is greater than or equal to this parameter.

Not effect yet.

Empty

Upgrade Rule

This parameter is a firmware upgrade script with the same syntax as Profile Rule. Defines upgrade conditions and associated firmware URLs.

Such as: https://192.168.20.17/G502_F107_S334.bin

Empty
