Reboot History on the Phone Web User Interface

You can view the reboot history as follows:
• From the phone web user interface
• From the IP phone screen
• From the phone Status Dump file (http://phoneIP/status.xml or http://phoneIP/admin/status.xml)
Reboot History on the Phone Web User Interface
On the Info > System Status page, the Reboot History section displays the device reboot history, the five
most recent reboot dates and times, and a reason for the reboot. Each field displays the reason for the reboot
and a time stamp that indicates when the reboot took place.
For example:
Reboot Reason 1: [08/13/14 06:12:38] User Triggered
Reboot Reason 2: [08/10/14 10:30:10] Provisioning
Reboot Reason 3: [08/10/14 10:28:20] Upgrade
The reboot history displays in reverse chronological order; the reason for the most recent reboot displays in
Reboot Reason 1.

Reboot History on the Cisco IP Phone Screen

Reboot History is located under Apps > Admin Settings > Status menu. In the Reboot History window, the
reboot entries displays in reverse chronological order, similar to the sequence that displays on the phone web
user interface.

Reboot History in the Status Dump File

The reboot history is stored in the Status Dump file (http://<phone_IP_address>/admin/status.xml).
In this file, tags Reboot_Reason_1 to Reboot_Reason_3 store the reboot history, as shown in this example:
<Reboot_History>
<Reboot_Reason_1>[08/10/14 14:03:43]Provisioning</Reboot_Reason_1>
<Reboot_Reason_2>[08/10/14 13:58:15]Provisioning</Reboot_Reason_2>
<Reboot_Reason_3>[08/10/14 12:08:58]Provisioning</Reboot_Reason_3>
<Reboot_Reason_4>
<Reboot_Reason_5>
<Reboot_History/>

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect Cisco IP Phone voice and video quality, and in some
cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following
activities:
• Administrative tasks, such as an internal port scan or security scan
• Attacks that occur on your network, such as a Denial of Service attack
