Usage Notes

Unified IP Phones use the TLS protocol when
securely registering with Cisco Unified CM.
For more information, refer to the Cisco Unified
Communications Manager Security Guide.
TFTP requires a TFTP server in your network,
which can be automatically identified from the
DHCP server. If you want a phone to use a TFTP
server other than the one specified by the DHCP
server, you must manually assign the IP address of
the TFTP server by using the Network Setup menu
on the phone.
For more information, go to the
in the Cisco Unified Communications Manager
System Guide.
Cisco Unified IP Phones transmit and receive RTP
streams, which utilize UDP.
