User's Manual 5. Automatic Configuration Options
Version 6.6 39 MediaPack Series
5.3 Option C - HTTP-based Automatic Updates
An HTTP (or HTTPS) server can usually be placed in the customer's core network, where
configuration and software updates will be available for download.
For example, assume the core network HTTP server is https://www.corp.com.
A master configuration *.ini file should be placed on the HTTP server, e.g.
https://www.corp.com/audiocodes/master.ini . This *.ini file could point to additional *.ini
files, auxiliary files (voice prompts, call progress tones, coefficients etc.) and software
upgrades (CMP files), all on the HTTP server or other HTTP servers in the core network.
The major advantage of this method is that the HTTP configuration can be checked
periodically, when the device is deployed at the end customer site; HTTP(S) is not
sensitive to NAT devices, allowing configuration to take place as needed, without on-site
intervention.
For additional security, the URL may contain a different port and a upassword.
The MP-1xx devices should only be configured with the URL of the initial *.ini file. There
are several ways of doing this:

Using Options A or B above - via TFTP at a staging warehouse. The INI file parameter
controlling the configuration URL is IniFileURL.

Private labeling at AudioCodes.

Using DHCP option 67 (see method D below).

Manually on-site, using the RS-232 port or web interface.
When the device is deployed at the end-customer site, local DHCP provides IP addressing
and DNS server information. The MP-1xx can then contact the HTTP server at the core
network and complete its configuration.
The URL can be a simple file name, or contain the device MAC address or IP address,
e.g.:
http://corp.com/config-<MAC>.ini turns into http://corp.com/config-00908f030012.ini
http://corp.com/<IP>/config.ini turns into http://corp.com/192.168.0.7/config.ini
Software upgrades may be performed using the parameter CmpFileURL. Inclusion of this
parameter in the master INI file will cause the MP-1xx to download and store the specified
software image.
Refer to the user documentation for additional examples of Automatic Updates.
This alternative does not require additional servers at the customer premises.
This alternative is NAT-safe.
