Cisco Unified Communications Manager, Release 8.5(1)
Procedure
Step 1 To display information on Session Trace, from the RTMT menus, choose CallManager > Call Process
> Session Trace.
The Session Trace screen displays.
Step 2 Enter the search criteria and Click Run.
Note You can search calls based on the following criteria: Calling Number/URI, Called Number/URI,
Start Time, and Duration. The search applies to the entire Unified CM cluster, not just the local
node. If any node fails to collect the trace files, the system displays an error message in the
bottom panel and pops up the message prompt to the user.
Click Yes to ignore the error and generate the table, based on the input.
Note In Calling Number/URI, Called Number/URI, you can use wild character "*" to match any
number of characters. For example, a search for 123* fetches numbers like "123", "123456",
"123*", "1234", etc.
If you want to search for numbers with a "*" in them, use "\*". For example, to search for a
Called Number like 12*45, enter 12\*45 in the search box.
If matching calls are found, the Matching Call pane displays Start Time, Calling DN, Original Called
DN, Final Called DN, and Termination Cause Code. The Termination Cause Code helps to identify the
failure calls, and provides the reason for the failure of the calls. The Termination Cause Code is
displayed in parenthesis followed by description.
Consider the following scenario:
• If the call is in progress or if the call trace logging is turned off after the call, the Termination Cause
Code column remains blank.
Note If cause code description is missing or if you want more information on the Termination Cause
Codes, refer the CDR cause codes in Cisco Unified Call Details Records Administration Guide.
Step 3 Select a call (a row) to trace.
By default, Include SIP Message check box is selected to view the associated SIP protocol messages or
call transactions.
Step 4 To generate the SIP Message Call Flow Diagram, click Trace Call. If you want to stop the generation of
the session information, click Cancel on the progress window.
