1 | Call Trace Filter parameters |
---|
|
|
Parameter | Description |
---|
Name | Specifies the name of the Call Trace filter that you are about to create. |
State | Specifies the state of this filter. The options are: Enabled: If enabled, this filter can be used for Call Trace.
Disabled (default): If disabled, it is not used for Call Trace.
|
Capture type | Specifies the type of logs that need to be captured while running the Call Trace. The options are: TRC logs : Capture trace information (.trc logs) only.TRC and PKT logs : Capture trace information (.trc logs) and media information (.pkt logs).
Note |
---|
You can even save the CLI call details and statistics by selecting this additional option, Also save CLI call details and statistics for traced calls (Call Detail Status, Call Media Status, Call Resource Detail Status). |
|
Detail level to log | Specifies the level of details that need to be capture in the log file when the trace is complete. The options are: Level 1 - Everything Level 2 - Everything but raw hex dump. Level 3 - Only external message information and errors. Level 4 - Only SIP PDU events.
Note |
---|
Level 4 Call Trace Filter conditions/behavior: - Level 4 filters based ONLY on
Peer IP Address . This call trace method does not trace/filter based on trunk group, called number, calling number, etc. - Configure a Level 4 filter with a wildcard
Peer IP Address of 255.255.255.255 to match ALL packets to/from any IP address. - Level 4 filters identify GCID when possible. However, some messages do not contain GCIDs and may have 0xfffffffff as the GCID (registration, notify, options ping, etc.).
|
Note |
---|
The Level 4 log is implemented to capture SIP Ladder diagrams (which is currently not supported) for the interpretation of calls. |
|
Capture calls that match these filters | Specifies the criteria that need to be captured in the logs in a Call Trace (these are optional). The options are: Called Number: Specifies the called party number to trace. An X or x means accept anything in that digit position. For example, 617xxx1212 would filter for all numbers 6170001212 through 6179991212. The % symbol acts as a wildcard for all remaining digits. For example, use 978% to trace all calls with a 978 prefix. Field Length is upto 30 characters.Calling Number: Specifies the calling party number to trace. An X or x means accept anything in that digit position. For example, 617xxx1212 would filter for all numbers 6170001212 through 6179991212. The % symbol acts as a wildcard for all remaining digits. For example, use 978% to trace all calls with a 978 prefix. Field Length is upto 30 characters.Contractor Number: Specifies the contractor number to trace. An X or x means accept anything in that digit position. For example, 617xxx1212 would filter for all numbers 6170001212 through 6179991212. The % symbol acts as a wildcard for all remaining digits. For example, use 978% to trace all calls with a 978 prefix. Field Length is upto 30 characters.
Note |
---|
For the above parameters, use "X" or "x" wildcard characters to match any single digit and "%" symbol to match any digits from that point forward. |
Redirecting Number: Specifies the redirecting number to trace. An X or x means accept anything in that digit position. For example, 617xxx1212 would filter for all numbers 6170001212 through 6179991212. The % symbol acts as a wildcard for all remaining digits. For example, use 978% to trace all calls with a 978 prefix. Field Length is upto 30 characters.CDDN number: Specifies the Called Directory Number to trace. Field Length is upto 30 characters.
Transfer capability: Specifies the transfer capability of the call trace filter. Options are:
Audio31Khz - 3.1 kHz Audio - ITC 3.1 kHz audio calls are traced. The default setting is disabled.Speech - ITC Speech based calls are traced. The default setting is disabled.Unrestricted - Calls with ITC Unrestricted are traced. The default setting is disabled.Unrestricted With Tones - Unrestricted Digital Information With Tones Announcements - Calls with ITC Unrestricted Digital Information With Tones Announcements are traced. The default setting is disabled.video - Calls with ITC Video are traced. The default setting is disabled.
Trunk Group: The name of a trunk group to trace. This string must match the trunk group name exactly. You cannot use wildcard characters for this argument. Field Length is upto 23 characters.Peer IP Address: Specifies the peer IpV4 or IpV6 Address for call tracing.
|
stop match | Specifies the criteria to stop the Call Trace. The options are: When a match occurs in this filter, stop trying to match the other filters Continue to try to match up to two other filters after a match is found in this filter (default)

Before you start a Call Trace, let us examine the conditions and the required fields to execute a Call Trace. The following conditions appear on the Call Trace Status and Settings panel.

|
|
Parameter | Description |
---|
Call Trace Duration | Specifies the duration for the Call Trace to run on the selected filter. The options are: Run trace until stopped (by clicking the Stop Trace button): If selected, the trace will keep running till it is stopped manually (by clicking the Stop Trace button).
Stop trace after __ minutes: If selected, add the number of minutes for the Call Trace to run. The value ranges from 1 to 360 minutes and the default value is 360 minutes.
|
Number of Matches (optional) | Specifies the number of times the Call Filter criteria should match before stopping the trace. The value ranges from 1 to 64 times. |
Trace Calls with errors of the type | Enable this option to trace the calls with error type as: none (default)— No SIP PDU logging, including validation/parsing errors.Any —Log all SIP PDUs that meet the requirement of the Parse Error, Out of Dialog, and Early Attempt options below.Parse Error —Log received SIP PDUs that fail parsing. If an error is detected by SIP signaling, the accompanying PDUs will not be associated with any dialog, including an existing dialog. Hence all in dialog and out of dialog PDUs are assigned to this category. If an error is detected at the front end pre-parser, the PDU is logged by this software and not forwarded to SIP signaling. This prevents an offending PDU from being logged by both the pre-parser and SIP signaling.Out of Dialog —Log incoming syntactically correct SIP PDUs (except INVITE) that do not belong to an existing dialog.Early Attempt —Logs incoming SIP PDUs that result in early termination of the call (by either the pre-parser or SIP signaling).

Call Trace Status | Displays the current status of the Call Trace. - When there are no trace running, the application states Call trace stopped with a red dot.
- when a trace is running, the application states Call trace running with a green dot.

To Run Call Trace
Follow these simple steps to run a Call Trace on a selected filter:
- Create a Call Trace Filter with the required parameters and conditions mentioned. Refer to To Create Call Filter section to activate the required parameters.
- The newly created filters are displayed in the Call Trace Filter panel.
- In the Call Trace Status and Settings panel, choose the required conditions to run the trace. Refer to Call Trace Status and Settings to know more on the conditions.
