Cisco IP phones support secure remote provisioning (configuration) and firmware
upgrades. An unprovisioned Cisco IP phone can receive an encrypted profile
specifically targeted for that device without requiring an explicit key by using a
secure first-time provisioning mechanism using SSL functionality.
User intervention is not required to initiate or complete a profile update or
firmware upgrade. If intermediate upgrades are required to reach a future upgrade
state from an older release, the Cisco IP phone upgrade logic is capable of
automating multi-stage upgrades. A profile resync is only attempted when the
Cisco IP phone is idle, because this might trigger a software reboot and
disconnect a call.
General purpose parameters 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 with client certificates.
The administrator can upgrade, reboot, restart, or resync Cisco IP phones by using
the phone web user interface. The administrator can also perform these tasks by
using a SIP notify message.
Configuration profiles are generated by using common, open-source tools that
integrate with service provider provisioning systems. (Provisioning is described in
detail in the Cisco Small Business IP Telephony Devices Provisioning Guide
