Chapter 7 Troubleshooting and Maintenance

Resolving Startup Problems

Verifying IP Addressing and Routing

You should verify the IP addressing and routing settings on the phone. If you are
using DHCP, the DHCP server should provide these values. If you have assigned
a static IP address to the phone, you must enter these values manually.

On the Cisco Unified IP Phone, press the

OK

button and choose

Settings >

Network Configuration > DHCP Enabled.

•

DHCP Enabled—Verify that

DHCP Enabled is set to

yes

. If it is not, check

your IP routing and VLAN configuration. Refer to

Troubleshooting Switch

Port Problems

, available at this URL:

http://www.cisco.com/warp/customer/473/53.shtml

•

IP Address, Subnet Mask, Default Router—If you have assigned a static IP
address to the phone, you must manually enter settings for these options. See
the

“Configuring Network Settings” section on page 4-3

for instructions.

If you are using DHCP, check the IP addresses distributed by your DHCP server.
Refer to

Understanding and Troubleshooting DHCP in Catalyst Switch or

Enterprise Networks

http://www.cisco.com/warp/customer/473/100.html#41

Verifying DNS Settings

If you are using DNS to refer to the TFTP server or to Cisco Unified CallManager,
you must ensure that you have specified a DNS server. You should also verify that
there is a CNAME entry in the DNS server for the TFTP server and for the
Cisco Unified CallManager system.

Verifying Cisco Unified CallManager Settings

On the Cisco Unified IP Phone, press the

OK

button and choose

Settings >

Network Configuration > CallManager 1 - 6

. The Cisco Unified IP Phone

attempts to open a TCP connection to all the Cisco Unified CallManager servers
that are part of the assigned Cisco Unified CallManager group. If none of these
options contain IP addresses or show Active or Standby, the phone is not properly
registered with Cisco Unified CallManager. See the

“Registering the Phone with

Cisco Unified CallManager” section on page 7-4

for tips on resolving this

problem.
