DescriptionParameter
If a resync operation fails because the IP Telephony
device was unable to retrieve a profile from the server,
or the downloaded file is corrupt, or an internal error
occurs, the device tries to resync again after a time
specified in seconds.
The valid formats are as follows:
• An integer
Example: An input of 300 indicates that the next
retry for resync occurs in 300 seconds.
• Multiple integers
Example: An input of 600,1200,300 indicates
that the first retry occurs in 600 seconds after the
failure, the second retry occurs in 1200 seconds
after the failure of the first retry, and the third
retry occurs in 300 seconds after the failure of
the second retry.
• A time range
Example, an input of 2400+30 indicates that
the next retry occurs in between 2400 and 2430
seconds after a resync failure.
If the delay is set to 0, the device does not try to resync
again following a failed resync attempt.
Resync Error Retry Delay
Maximum delay (in seconds) the phone waits before
performing a resynchronization.
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
resynchronizing. 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.
The valid value ranges between 0 and 65535.
The default value is 14,400 seconds.
