V7122 Gateway User Guide

The Automatic Update mechanism assumes the external 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
gateway may reset itself repeatedly. To overcome this problem, adjust the update
frequency (AutoUpdateFrequency)
Three methods are used to activate the Automatic Update mechanism:
After the gateway starts-up (see the Startup process described in
Figure 88
).
At a configurable time of the day (for example, 18:00). This option is disabled by default.
At fixed intervals (for example, every 60 minutes). This option is disabled by default.
The following
ini
file example can be used to activate the Automatic Update mechanism.
Figure 87
Example of an
ini
File Activating the Automatic Update Mechanism
# DNS is required for specifying domain names in URLs
DnsPriServerIP = 10.1.1.11
# Load an extra configuration ini file using HTTP
IniFileURL = 'http://webserver.corp.com/AudioCodes/inifile.ini'
# Load Call Progress Tones file using HTTPS
CptFileUrl = 'https://10.31.2.17/usa_tones.dat'
# Load Voice Prompts file using FTPS with user ‘root’ and password ‘wheel’
VPFileUrl = 'ftps://root:[email protected]/vp.dat'
# Update every day at 03:00 AM
AutoUpdatePredefinedTime = '03:00'
# Note: The cmp file isn’t updated since it is disabled by default
(AutoUpdateCmpFile).
See the following notes:
When HTTP or HTTPS are used, the gateway contacts the Web server/s and queries for
the requested files. The
ini
file is loaded only if it was modified since the last automatic
update. The
cmp
file is loaded only if its version is different from the version stored on
the gateway’s non-volatile memory. All other auxiliary files (for example, CPT) are
updated only once. To update a previously-loaded auxiliary file, you must update the
parameter containing its URL.
To load different configurations (
ini
files) for specific gateways, add the string ‘<MAC>’ to
the URL. This mnemonic is replaced with the gateway’s hardware MAC address.
Resulting in an
ini
file name request that contains the gateway’s MAC address.
To automatically update the
cmp
file, use the parameter ‘CmpFileURL’ to specify its
name and location. As a precaution (in order to protect the gateway from an accidental
update) the Automatic Update mechanism doesn’t apply to the
cmp
file by default.
Therefore, (to enable it) set the parameter ‘AutoUpdateCmpFile’ to 1.
