7 Provisioning Basics Provisioning Capabilities Provisioning Capabilities The Cisco IP phones provide for secure provisioning and remote upgrade. Provisioning is achieved through configuration profiles transferred to the device via TFTP, HTTP, or HTTPS. The Cisco IP phones can be configured to automatically resync their internal configuration state to a remote profile periodically and on power up. The automatic resyncs are controlled by configuring the desired profile URL into the device. The SPA9000 accepts profiles in XML format, or alternatively in a proprietary binary format, which is generated by a profile compiler tool, SIP Profile Compiler (SPC), available from Cisco. The SPA9000 supports up to 256-bit symmetric key encryption of profiles. For the initial transfer of the profile encryption key (initial provisioning stage), the SPA9000 can receive a profile from an encrypted channel (HTTPS with client authentication), or it can resync to a binary profile generated by the Cisco SIP profile compiler. In the latter case, the SIP profile compiler can encrypt the profile specifically for the target SPA9000, without requiring an explicit key exchange. Remote firmware upgrade is achieved via TFTP or HTTP or HTTPS (TFTP or HTTP for WIP310). Remote upgrades are controlled by configuring the desired firmware image URL into the Cisco IP phone via a remote profile resync. Provisioning Configuration from Phone Keypad Remote provisioning can be performed from a phone keypad. After the user enters the IP address of the provisioning server, the unit resyncs to a known path name. This feature enables service providers to have VARs install and provision Cisco phones. 134 Cisco SPA and Wireless IP Phone Administration Guide
