Appendix A: How to Use the Update Server

A.1 Summary
Automatic update is based on configuration and firmware information stored on a
standard web server and retrieved by the devices on a regular basis.
There are 2 modules in the device which work in tandem. The first is known as "UP0" and
actually executes the upload and download of configuration information as well as the
download of updated firmware. UP0 is controlled by commands as described below.
The second module is known as "UP1". It serves to poll a given website for changed
configuration information. If certain conditions are met, UP1 will issue commands to UP0
to perform the requested updates.
UP0 can also receive commands from the "Update clients" page of the PBX
Administration user interface.
A.1.1 System Requirements
One or more regular Web Server that can be accessed by all devices are required. This has
been tested with Microsoft IIS and Apache, but any regular Web Server should do.
For best results, the Web Server should be able to maintain a large number of HTTP
sessions simultaneously, since potentially all devices may attempt a configuration update
at the same time. For example, Microsoft's Personal Web Server is not adequate, since it
only support 10 simultaneous sessions.
Following URLs are supported: HTTP, HTTPS and TFTP.
A.1.2 Installation
To be able to upload (save) device configuration information on the web server, it must
allow HTTP PUT requests. All other functions require HTTP GET permissions only.
Since all HTTP requests are performed unauthenticated, the website used must allow
anonymous read (and potentially write) access. You may want to restrict access to that site
to certain network address ranges.
Configure a Microsoft IIS URL to allow PUT commands:
1 Create a directory where you want to save configurations to
2 Create a virtual directory in Microsoft's IIS manager
3 Select "read" and "write" access
No installation is needed on the IPBS/IPBLs.
A.1.3 Configuration
See 8.1.4 Configure Automatic Firmware Update
IPBS/IPBLs for automatic update.
The URL parameter must point to the site where the file containing the maintenance
commands is stored. Note that in this URL, no host names are supported. The web servers
IP address must be used.
A.1.4 Setting the UP1 Parameters
The applet saves the configuration in a line starting config change UP1.
