Usage Notes
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 using the Network
Configuration menu on the phone.
Cisco Unified IP Phones transmit
and receive RTP streams, which
utilize UDP.
