Provisioning Basics Upgrading, Resyncing, and Rebooting Phones 6 Upgrading, Resyncing, and Rebooting Phones 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. 1- 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 web interface. The administrator can also perform these tasks using a SIP notify message and bypassing the web interface. 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: Cisco IP phone web UI: Provisioning > Firmware Upgrade > Upgrade Enable: yes Use the following syntax to upgrade firmware on a phone: http://phone-ip-address/admin/upgrade?protocol://servername[:port]]/firmware-path • Protocol defaults to TFTP. • Server name is the host requesting the URL.
