Configuring IP
network If the Cisco Wireless IP Phone is using DHCP to
obtain an IP address, the phone queries the
DHCP server to obtain one. If you are not using
DHCP in your network, you must assign a static
IP address to each phone locally.
In addition to assigning an IP address, the
DHCP server directs the Cisco Wireless
IP Phone to a TFTP server. If the phone has a
statically defined IP address, you must
configure the TFTP server IP address locally on
the phone; the phone then contacts the TFTP
server directly.

5. Downloading Load
ID The Cisco Wireless IP Phone checks to verify
that the proper firmware is installed or if new
firmware is available to download.
Cisco CallManager informs devices using .cnf
or .cnf.xml format configuration files of their
load ID. Devices using .xml format
configuration files receive the load ID in the
configuration file.
