Chapter 9 Troubleshooting and Maintenance Cisco Unified IP Phone Resets Unexpectedly • Checking Power Connection, page 9-8 Verifying the Physical Connection Verify that the Ethernet connection to which the Cisco Unified IP Phone is connected is up. For example, check whether the particular port or switch to which the phone is connected is down and that the switch is not rebooting. Also make sure that there are no cable breaks. Identifying Intermittent Network Outages Intermittent network outages affect data and voice traffic differently. Your network might have been experiencing intermittent outages without detection. If so, data traffic can resend lost packets and verify that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather than retransmitting a lost network connection, the phone resets and attempts to reconnect its network connection. If you are experiencing problems with the voice network, you should investigate whether an existing problem is simply being exposed. Verifying DHCP Settings Follow this process to help determine if the phone has been properly configured to use DHCP: 1. Verify that you have properly configured the phone to use DHCP. See the "Network Configuration Menu" section on page 4-5 for more information. 2. Verify that the DHCP server has been set up properly. 3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days. Checking Static IP Address Settings If the phone has been assigned a static IP address, verify that you have entered the correct settings. See the "Network Configuration Menu" section on page 4-5 for more information. Verifying Voice VLAN Configuration If the Cisco Unified IP Phone appears to reset during heavy network usage (for example, following extensive web surfing on a computer connected to same switch as phone), it is likely that you do not have a voice VLAN configured. Isolating the phones on a separate auxiliary VLAN increases the quality of the voice traffic.

Troubleshooting and Maintenance

Cisco Unified IP Phone Resets Unexpectedly

•

Checking Power Connection, page 9-8

Verifying the Physical Connection

Verify that the Ethernet connection to which the Cisco Unified IP Phone is connected is up. For example,

check whether the particular port or switch to which the phone is connected is down and that the switch

is not rebooting. Also make sure that there are no cable breaks.

Identifying Intermittent Network Outages

Intermittent network outages affect data and voice traffic differently. Your network might have been

experiencing intermittent outages without detection. If so, data traffic can resend lost packets and verify

that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather

than retransmitting a lost network connection, the phone resets and attempts to reconnect its network

connection.

If you are experiencing problems with the voice network, you should investigate whether an existing

problem is simply being exposed.

Verifying DHCP Settings

Follow this process to help determine if the phone has been properly configured to use DHCP:

Verify that you have properly configured the phone to use DHCP. See the

“Network Configuration

Menu” section on page 4-5

for more information.

Verify that the DHCP server has been set up properly.

Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.

Checking Static IP Address Settings

If the phone has been assigned a static IP address, verify that you have entered the correct settings. See

the

“Network Configuration Menu” section on page 4-5

for more information.

Verifying Voice VLAN Configuration

If the Cisco Unified IP Phone appears to reset during heavy network usage (for example, following

extensive web surfing on a computer connected to same switch as phone), it is likely that you do not

have a voice VLAN configured.

Isolating the phones on a separate auxiliary VLAN increases the quality of the voice traffic. See the

“Understanding How the Cisco Unified IP Phone Interacts with the VLAN” section on page 2-2

for

details.
