Registering the Phone with Cisco Unified CallManager
A Cisco Unified IP Phone can register with a Cisco Unified CallManager server
only if the phone has been added to the server or if auto-registration is enabled.
Review the information and procedures in the
“Adding Phones to the Cisco
Unified CallManager Database” section on page 2-9
to ensure that the phone has
been added to the Cisco Unified CallManager database.
To verify that the phone is in the Cisco Unified CallManager database, choose
Device > Phone > Find
from Cisco Unified CallManager Administration to
search for the phone based on its MAC Address. For information about
determining a MAC address, see the
“Determining the MAC Address for a Cisco
Unified IP Phone” section on page 2-12
.
If the phone is already in the Cisco Unified CallManager database, its
configuration file may be damaged. See the
“Creating a New Configuration File”
section on page 7-6
for assistance.
Checking Network Connectivity
If the network is down between the phone and the TFTP server or
Cisco Unified CallManager, the phone cannot start up properly. Ensure that the
network is currently running.
Verifying TFTP Server Settings
The Cisco Unified IP Phone uses the TFTP Server 1 setting to identify the primary
TFTP server used by the phone. You can determine this setting by pressing the
OK
button and choosing
Settings > Network Configuration > TFTP Server
.
If you have assigned a static IP address to the phone, you must manually enter a
setting for the TFTP Server 1 option. You can also enable the phone to use a
dynamic TFTP server.
For more information on configuring network settings, see the
“Configuring
Network Settings” section on page 4-3
.
