For information about how to manage the MIC for your phone, refer to the "Using the Certificate Authority Proxy Function" chapter in Cisco Unified Communications Manager Security Guide.

CFG file not found

The name-based and default configuration file was not found on the TFTP Server.

The configuration file for a phone is created when the phone is added to the Cisco Unified Communications Manager database. If the phone has not been added to the Cisco Unified Communications Manager database, the TFTP server generates a CFG File Not Found response.

Phone is not registered with Cisco Unified Communications Manager.

You must manually add the phone to Cisco Unified Communications Manager if you are not allowing phones to auto-register. See the "Methods for Adding Phones to Cisco Unified Communications Manager" section for details.

If you are using DHCP, verify that the DHCP server is pointing to the correct TFTP server.

If you are using static IP addresses, check configuration of the TFTP server. See the "Configuring IP Network Settings" section for details on assigning a TFTP server.

CTL Installed

A certificate trust list (CTL) file is installed in the phone.

None. This message is informational only.

For more information about the CTL file, refer to Cisco Unified Communications Manager Security Guide.

CTL update failed

The phone could not update its certificate trust list (CTL) file.

Problem with the CTL file on the TFTP server.

For more information, refer to Cisco Unified Communications Manager Security Guide.

Viewing Call Statistics

You can access the Call Statistics screen on the phone to display counters, statistics, and voice quality metrics in these ways:

During call—You can view the call information by pressing the Select button twice rapidly.

After the call—You can view the call information captured during the last call by displaying the Call Statistics screen.


Note You can remotely view the call statistics information by using a web browser to access the Streaming Statistics web page. For more information about remote monitoring, see Chapter 9 "Monitoring the Cisco Unified Wireless IP Phone Remotely."


A single call can have multiple voice streams, but data is captured for only the last voice stream. A voice stream is a packet stream between two endpoints. If one endpoint is put on hold, the voice stream stops even though the call is still connected. When the call resumes, a new voice packet stream begins, and the new call data overwrites the former call data.

To display the Call Statistics screen for information about the last voice stream, follow these steps:

Procedure


Step 1 Press Settings > Status.

Step 2 Scroll to and select Call Statistics; the list of statistics appears.

Step 3 Use the Navigation button to scroll through the items in the Call Statistics screen.
