Feature Description
Image authentication Signed binary files (with the extension .sbn) prevent tampering with the firmware image before
it is loaded on a phone. Tampering with the image causes a phone to fail the authentication
process and reject the new image.
802.1X Authentication The Cisco Unified IP Phone can use 802.1X authentication to request and gain access to the
network. See Supporting 802.1X Authentication on Cisco Unified IP Phones, page 1-16 for more
information.
