Cisco Unified SIP Phone 3911 Administration Guide for Cisco Unified Communications Manager
OL-14029-01
Registering the Phone with Cisco Unified Communications Manager
A Cisco Unified IP Phone can register with a Cisco Unified Communications
Manager 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 Communications Manager Database”
section on page 2-9
to ensure that the phone has been added to the Cisco Unified
Communications Manager database.
To verify that the phone is in the Cisco Unified Communications Manager
database, choose
Device > Phone > Find
from Cisco Unified Communications
Manager 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 Communications Manager 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
Communications Manager, 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
.
