Maintenance
This section includes the following topics
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 Cisco Unified IP Phones with QRT. When you do so, users can report problems with phone
calls pressing QRT. This softkey is available only when the Cisco Unified IP Phone is in the Connected,
Connected Conference, Connected Transfer, or OnHook states.
When a user presses QRT, 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 if the destination device is a Cisco Unified IP Phone.
For more information about using QRT, see the Cisco Unified Serviceability Administration Guide.
