Provisioning Basics
Upgrading, Resyncing, and Rebooting Phones
Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide 172

General purpose parameters are provided to help service providers manage the
provisioning process. Each Cisco IP phone can be configured to periodically
contact a normal provisioning server (NPS). Communication with the NPS does not
require the use of a secure protocol because the updated profile is encrypted by
a shared secret key. The NPS can be a standard TFTP, HTTP or HTTPS server.
The administrator can upgrade, reboot, restart, or resync Cisco IP phones using
the configuration utility. The administrator can also perform these tasks using a SIP
notify message and bypassing the configuration utility.
Upgrading Firmware on a Phone
Use the upgrade URL to upgrade firmware on the Cisco IP phone. You can
upgrade from either a TFTP or HTTP server. The Upgrade Enable parameter on
the Provisioning web page must be set to yes.
STEP 1 Log in to the configuration utility.
STEP 2 Click the Provisioning tab.
STEP 3 Under Firmware Upgrade, in the Upgrade Enable field, choose yes.
Enter the upgrade command into your browser’s address bar to upgrade firmware
on a phone. Use the following syntax:
http://phone-ip-address/admin/upgrade?protocol://server-
name[:port]]/firmware-path
• Protocol defaults to TFTP.
• Server name is the host requesting the URL.
• Port is the port of the protocol being used (for example, 69 for TFTP or 80
for HTTP).
• Firmware-path defaults to /spa.bin (for example, http://192.168.2.217/
admin/upgrade?tftp://192.168.2.251/spa.bin) for SPA phones and /
wip310.img for the WIP310. The firmware-pathname is typically the file
name of the binary located in a directory on the TFTP or HTTP server.
Firmware Upgrade Parameters
The following table defines the function and usage of each parameter in the
