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 2-13

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 of a Cisco Unified IP Phone” section on page 2-20

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 9-7

for assistance.

Symptom: Cisco Unified IP Phone Unable to Obtain IP Address

If a phone is unable to obtain an IP address when it starts up, the phone may be

not be on the same network or VLAN as the DHCP server, or the switch port to

which the phone is connected may be disabled.

Make sure that the network or VLAN to which the phone is connected has access

to the DHCP server, and make sure that the switch port is enabled.

Cisco Unified IP Phone Resets Unexpectedly

If users report that their phones are resetting during calls or while idle on their

desk, you should investigate the cause. If the network connection and

Cisco Unified Communications Manager connection are stable, a Cisco Unified

IP Phone should not reset on its own.

Typically, a phone resets if it has problems connecting to the Ethernet network or

to Cisco Unified Communications Manager. These sections can help you identify

the cause of a phone resetting in your network:
