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 the
“Supporting
802.1X Authentication on Cisco Unified IP Phones” section
on page 1-23
