Setting Up Call Detail Records Logging
Using Path Analysis with Cisco CallManager requires the installation of the Common Management Foundation 1.1.1 Voice Manager patch on the CiscoWorks2000 server.
Understanding Path Analysis
Path Analysis, a diagnostic application, traces connectivity between two specified points on a network. It analyzes both physical and logical paths (Layer 2 and Layer 3) taken by packets flowing between those points.
After a call completes, PathTool traces the route of audio packets by specifying the directory number of the calling and called parties. This applies to calls among any of the following endpoints: Cisco IP phones, analog devices connected to a station gateway, or trunk gateways (analog or digital).
For more information, consult CiscoWorks2000 online help.
The information presented here assists you in setting up Cisco CallManager. You can display the paths that are traced in the form of maps, trace logs, or tables in CiscoWorks2000 Campus Manager.

Setting Up Call Detail Records Logging
You can activate Voice over IP (VoIP) traces only when Cisco CallManager is installed with call detail record (CDR) logging enabled. The default status specifies disabled.
From the Cisco CallManager Administration window, perform the following procedure to enable CDR logging.
Step 1
Choose Service > Service Parameters.
Step 2
Choose IP address of your Cisco CallManager server.
Step 3
Click the Next button.
Step 4
Choose the Cisco CallManager service.
Step 5
In the Parameter Value field, choose True for the Cdr Enabled Flag service parameter.
Step 6
Click the Update button.
Call detail records start logging immediately.
Caution ![](../../../../../../i/templates/blank.gif)
Tracing voice connectivity requires that CDR logging be enabled on
every Cisco CallManager server in a cluster.
