General Troubleshooting Tips

Table 9-2

 provides general troubleshooting information for the Cisco Unified IP Phone.

802.1X Not Enabled

Phone cannot obtain a DHCP-assigned IP address These errors typically indicate that 802.1X 

authentication is not enabled on the phone. To 
enable it, see the 

“802.1X Authentication and 

Status” section on page 4-34.

Phone does not register with 
Cisco Unified Communications Manager

Phone status display as “Configuring IP” or 
“Registering” 

802.1X Authentication Status displays as 
“Disabled” 

Status menu displays DHCP status as timing out 

Factory Reset Deleted 802.1X Shared Secret

Phone cannot obtain a DHCP-assigned IP address These errors typically indicate that the phone has 

completed a factory reset (see the 

“Performing a 

Factory Reset” section on page 9-15

) while 

802.1X was enabled. A factory reset deletes the 
shared secret, which is required for 802.1X 
authentication and network access. To resolve this, 
you have two options:

  •

Temporarily disable 802.1X authentication on 
the switch.

  •

Temporarily move the phone to a network 
environment that is not using 802.1X 
authentication.

Once the phone starts up normally in one of these 
conditions, you can access the 802.1X 
configuration menus and re-enter the shared secret 
(see the 

“802.1X Authentication and Status” 

section on page 4-34

).

Phone does not register with 
Cisco Unified Communications Manager

Phone status display as “Configuring IP” or 
“Registering”

Cannot access phone menus to verify 802.1X 
status

Cisco Unified IP Phone Troubleshooting 

Summary

Explanation

Daisy-chaining IP phones

Daisy chaining (connecting an IP phone to another IP phone 
through the access port) is not supported. Each IP phone should 
directly connect to a switch port.

Poor quality when calling digital 
mobile phones using the G.729 
protocol

In Cisco Unified Communications Manager, you can configure the 
network to use the G.729 protocol (the default is G.711). When 
using G.729, calls between an IP phone and a digital mobile phone 
will have poor voice quality. Use G.729 only when absolutely 
necessary.
