Parameter

Description

NameSpecifies 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 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). These files are saved as .out files.

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 traces all the SIP PDU events (without logging other trace messages) at line-rate without dropping any PDUs. These traces are used by SIP Ladder feature for further analysis.
  • 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, and so on).
  • No other trace filters can be running at the same time as the level 4 trace (that is, do not run a level 1, 2, or 3 trace at the same time as the level 4 trace.)


Note

The Level 4 log is implemented to capture SIP Ladder diagrams 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.
    NOTE: The following characters are accepted by the SBC when specifying the Call Filter search criteria :
    • Digits 0-9

    • Plus (+) symbol

    • Wilcard characters (“x” or “X”) to match any single digit within the search string

    • Wilcard symbol (%) to match any digits from that point forward

  • 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)
