Understanding the Phone Startup Process
3. Configuring VLAN If the Cisco Unified IP Phone is connected to a
Cisco Catalyst switch, the switch next informs the
phone of the voice VLAN defined on the switch.
The phone needs to know its VLAN membership
before it can proceed with the Dynamic Host
Configuration Protocol (DHCP) request for an IP
address.

4. Obtaining an IP
Address
If the Cisco Unified 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. • Understanding the

5. Accessing a TFTP
Server
In addition to assigning an IP address, the DHCP
server directs the Cisco Unified IP Phone to a
TFTP Server. If the phone has a statically defined
IP address, you must configure the TFTP server
locally on the phone; the phone then contacts the
TFTP server directly.

6. Requesting the
Configuration File and
the Profile File
The TFTP server has configuration files and
profile files. A configuration file includes
parameters for connecting to
Cisco Unified CallManager and information about
which image load a phone should be running. A
profile file contains various parameters and values
for phone and network settings. • Understanding
