File Download Sequence - AudioCodes Mediant 3000 User Manual

•
One-time File Download: This is applicable to software (.cmp) and Auxiliary
(e.g., call progress tone / CPT) 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:
♦
CptFileURL = 'https://www.company.com/call_progress.dat'
♦
(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:
♦
CmpFileUrl =
'https://www.company.com/device/v.6.80A.227.005.cmp'
♦
(config-system)# automatic-update
(automatic-update)# firmware
https://www.company.com/device/v.6.80A.227.005.cmp
Notes:
•
For one-time file download, the HTTP Get request sent by the device does not
include the If-Modified-Since header. Instead, the HTTP-User-Agent header can
be used in the HTTP Get request to determine whether firmware update is
required.
•
When downloading SSL certificates (Auxiliary file), it is recommended to use
HTTPS with mutual authentication for secure transfer of the SSL Private Key.
5. If the device receives an HTTP 301/302/303 redirect response from the provisioning
server, it establishes a connection with the new server at the redirect URL and re-
sends the HTTP Get request.

39.3.6 File Download Sequence

Whenever the Automatic Update feature is triggered (see 'Triggers for Automatic Update'
on page 627), the device attempts to download each file from the configured URLs, in the
following order:
1. ini file
2. Periodic software file (.cmp) download
3. One-time software file (.cmp) download
4. Auxiliary file(s)
The following files automatically instruct the device to reset:

Periodic software file (.cmp)

One-time software file (.cmp)
When multiple files requiring a reset are downloaded, the device resets only after it has
downloaded and installed all the files. However, you can explicitly instruct the device to
immediately reset for the following files:
