The SRTP media encryption feature provides encrypted media. A
preshared secret is embedded in the Nortel IP Phone to generate and to
exchange encryption parameters without any Call Server involvement.

"Features overview" on page 493 and System Security Management
(NN43001-604).

40 Upgrade the IP Phone 2007 firmware.
The IP Phone 2007 supports remote firmware upgrades through a TFTP
process and an automated UFTP process.
The method to upgrade the firmware depends on the following Call Server
software:
• For Succession Release 3.0 or CS 1000 Release 4.0, the TFTP
Server is required to download the current firmware. Enter the TFTP
Server IP address at the prompt.
• For CS 1000 Release 4.5 and later, use either a TFTP Server to
upgrade the firmware (at the prompt accept the default entry of
0.0.0.0), or UFTP to download the current firmware.
For further information about TFTP Server configuration, see
