Linksys SPA9x2 Phone Administration Guide 57
Upgrading, Resyncing, and Rebooting Phones
Provisioning Basics
• Firmware-path defaults to /spa.bin (for example, http://192.168.2.217/admin/
upgrade?tftp://192.168.2.251/spa.bin). The firmware-pathname is typically the file
name of the binary located in a directory on the TFTP or HTTP server.
Resyncing a Phone
You can resync a SPA9x2 phone to a specific remote profile. The configuration of the phone you
resync will match the configuration of the remote phone. The SPA9x2 can be configured to
resync its internal configuration state to a remote profile periodically and on power up.
NOTE: The SPA9x2 resyncs only when it is idle.
Use the following syntax to resync a phone’s profile to a profile on a TFTP, HTTP, or HTTPS server:
http://spa9x2-ip-addr/admin/resync?protocol://server-name[:port]/profile-pathname
• Parameter following resync? defaults to the Profile Rule setting on the web server
Provisioning page.
• Protocol defaults to TFTP.
• Server-name defaults to the host requesting the URL.
•Port defaults to:
– 69 for TFTP

192.168.2.217admin/resync?tftp://192.168.2.251/spaconf.cfg).
Rebooting a Phone
You can remotely reboot a SPA9x2 phone if needed.
Use the following syntax to reboot a phone:
http://spa9x2-ip-addr/admin/reboot
SPA9x2 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
SPA9x2 can receive an encrypted profile specifically targeted for that device without requiring
an explicit key. a secure first-time provisioning mechanism using SSL functionality. 1-3
User intervention is not required to initiate or complete a profile update or firmware upgrade.
The SPA9x2 upgrade logic is capable of automating multi-stage upgrades, if intermediate
