Intermittent Network Outages

Solution

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

whether the particular port or switch to which the phone connects is down and that the switch is not rebooting.

Also ensure that no cable breaks exist.

Intermittent Network Outages

Problem

Your network may be experiencing intermittent outages.

Solution

Intermittent network outages affect data and voice traffic differently. Your network might be 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 to the network. Contact the system

administrator for information on known problems in the voice network.

Problem

The DHCP settings may be incorrect.

Solution

The following suggestions can help you determine if the phone has been properly configured to use DHCP:

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

more information.

2. Verify that the DHCP server has been set up properly.

3. Verify the DHCP lease duration. We recommend that you set the lease duration to 8 days.

Cisco Unified IP Phones send messages with request type 151 to renew their DHCP address leases. If the

DHCP server expects messages with request type 150, the lease renewal is denied, forcing the phone to restart

and request a new IP address from the DHCP server.

Problem

The static IP address assigned to the phone may be incorrect.

Solution

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