Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide
Cisco IP phones support secure remote provisioning and firmware upgrades. You
can generate configuration profiles using common, open-source tools that
integrate with service provider provisioning systems. Supported transport
protocols include TFTP, HTTP, and HTTPS with client certificates.
256-bit symmetric key encryption of profiles is supported. In addition, an
unprovisioned Cisco IP phone can receive an encrypted profile specifically
targeted for that device without requiring an explicit key. a secure first-time
provisioning mechanism using SSL functionality.
User intervention is not required to initiate or complete a profile update or
firmware upgrade. The Cisco IP phone upgrade logic is capable of automating
multi-stage upgrades, if intermediate upgrades are required to reach a future
upgrade state from an older release. A profile resync is only attempted when the
Cisco IP phone is idle, because this may trigger a software reboot.
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.
Log in to the configuration utility.
Click the Provisioning tab.
Under Firmware Upgrade, in the Upgrade Enable field, choose yes.
