In this way, a service provider is given full control over which parameters become end-user inaccessible,
read-only, or read-write following provisioning of the SPA.
In its most basic configuration, the SPA-841 resyncs to the provisioning server periodically, downloading
the configuration profile specified as a URL in the Profile_Rule parameter.
Eample:
Profile_Rule “http://my.local.server.net/profile-path/spa841.cfg” ;
Please refer to the Sipura SPA Provisioning Guide for a more exhaustive description of the available
provisioning features in the SPA-841.
13 Provisioning
Flow
Provisioning a pool of SPA841 phones consists of two main steps:
•
Configuring all devices to their common provisioning environment, and
•
Configuring each device to their unique network attributes.
The first step (also known as pre-provisioning) includes programming initial parameters such as a resync
URL, a resync period, and an administrator password.
The second step (provisioning proper) manages the SPA841 under normal provisioned conditions,
configuring all pertinent parameters for normal operation unique to each device.
Pre-Provisioning
New units need to be told where to find their configuration within the customer’s network. This step can
be automated within a local network. By default, each SPA841 will resync out-of-the-box to the
configuration profile spa841.cfg located in the virtual root directory of the TFTP boot server specified by
the Local Area Network’s DHCP parameters (DHCP option 66). This shared configuration profile can
redirect the SPA841 to its eventual home URL.
This pre-provisioning step is typically performed in a controlled environment. For sufficiently large volume
orders, Sipura can customize the pre-provisioning parameters into each unit at the time of manufacture.
For instance, pre-provisioning can be as simple as configuring only the Profile Rule parameter with the
final URL of the phone’s profile.
For example:
Profile_Rule “http://prov.voip.one.com/spa841/profile/$MA.cfg” ;
Here, the macro variable $MA expands to the MAC address of each specific SPA841 (e.g. $MA.cfg would
expand to 000e08dabcde.cfg for a unit with that MAC address).
