Provisioning Flow; Pre-Provisioning; Provisioning Proper - Linksys SPA941 Administration Manual

• Provisioning Flow

Provisioning a pool of SPA941 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 SPA941 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 SPA941 will resync out-of-the-box to the
configuration profile spa941.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 SPA941 to its eventual home URL.
This pre-provisioning step is typically performed in a controlled environment. For sufficiently large volume
orders, Linksys 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/spa941/profile/$MA.cfg" ;
Here, the macro variable $MA expands to the MAC address of each specific SPA941 (e.g. $MA.cfg would
expand to 000e08dabcde.cfg for a unit with that MAC address).

Provisioning Proper

Once the SPA941 is pre-provisioned it will resync periodically to the specified profile URL, maintaining its
internal configuration synchronized with the provisioning server. Typically, a separate configuration file is
maintained for each SPA941 in the network.
The periodic profile would contain individual information about each phone, including account identifiers
and credentials.
