Chapter 9 Troubleshooting and Maintenance
Using the Quality Report Tool
After you press these keys, the line buttons on the phone flash red and the phone
goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the
main screen appears.
Using the Quality Report Tool
The Quality Report Tool (QRT) is a voice quality and general problem-reporting
tool for the Cisco Unified IP Phone. The QRT feature is installed as part of the
Cisco Unified Communications Manager installation.
You can configure users’ Cisco Unified IP Phones with QRT. When you do so,
users can report problems with phone calls by pressing the QRT softkey. This
softkey is available only when the Cisco Unified IP Phone is in the Connected,
Connected Conference, Connected Transfer, and/or OnHook states.
When a user presses the QRT softkey, a list of problem categories appears. The
user selects the appropriate problem category and this feedback is logged in an
XML file. Actual information logged depends on the user selection and whether
the destination device is a Cisco Unified IP Phone.
For more information about using QRT, refer to Cisco Unified Communications
Manager Serviceability Administration Guide, Cisco Unified Communications
Manager Serviceability System Guide, and Cicso Communications Manager
Features and Services Guide.
Monitoring the Voice Quality of Calls
To measure the voice quality of calls that are sent and received within the network,
Cisco Unified IP Phones use these statistical metrics that are based on
concealment events. The DSP plays concealment frames to mask frame loss in the
voice packet stream.
• Concealment Ratio metrics—Show the ratio of concealment frames over total
speech frames. An interval conceal ratio is calculated every 3 seconds.
