You can also enable the device to run a CRC on the downloaded configuration
file (ini) to determine whether the file has changed in comparison to the
previously downloaded file. Depending on the CRC result, the device can install
or discard the downloaded file. For more information, see 'Cyclic Redundancy
Check on Downloaded Configuration Files' on page 890.
Note:
• When this method is used, there is typically no need for the provisioning server to
check the device’s current firmware version using the HTTP-User-Agent header.
• The Automatic Update feature assumes that the Web server conforms to the
HTTP standard. If the Web server ignores the If-Modified-Since header or doesn’t
provide the current date and time during the HTTP 200 OK response, the device
may reset itself repeatedly. To overcome this problem, modify the update
frequency, using the ini file parameter AutoUpdateFrequency or CLI command
configure system > automatic update > update-frequency.
• One-time File Download: This is applicable to software (.cmp) and Auxiliary
(e.g., License Key, CPT and Dial Plan) files. The device downloads these files
only once, regardless of how many times the device may repeat the Automatic
Update process. Once they are downloaded, the device discards their configured
URLs. To update these files again, you need to configure their URL addresses
and filenames again. Below is an example of how to configure URLs for some of
these files:
Auxiliary Files:
♦ ini:
CptFileURL =
'https://www.company.com/call_progress.dat'
FeatureKeyURL =
'https://www.company.com/License_Key.txt'
♦ CLI:
(config-system)# automatic-update
(automatic-update)# call-progress-tones
http://www.company.com/call_progress.dat
(automatic-update)# tls-root-cert https://company.com/root.pem
Software (.cmp) File:
♦ ini:
CmpFileUrl =
'https://www.company.com/device/v.7.20A.000.038.cmp'
♦ CLI:
(config-system)# automatic-update
(automatic-update)# firmware
https://www.company.com/device/v.7.20A.000.038.cmp
