Voice Call Debug Filtering Overview

Use voice call debug filtering to get selected debugging traces for voice calls. This feature allows you to filter and trace voice call debug messages based on selected filtering criteria, reducing the volume of output for more efficient troubleshooting.

Restrictions for Voice Call Debug Filtering

  • End-to-end filtering between gateways is not supported.
  • Filtering for CAS, IOS-AAA, IVR Version 1.0, media, and VoiceXML is not supported.
  • Matching conditions cannot be set for specific signaling protocols.
  • Matching conditions based on current DSP information are not supported.

Information About Voice Call Debug Filtering

Information from using debug commands for voice calls is crucial for troubleshooting, but the volume of raw data can be very large. In order to isolate the most valuable data, use the Voice Call Debug Filtering feature. This feature allows the debug output for the voice call to be filtered according to a variety of criteria, including:

  • Calling party number with prefix
  • Called party number with prefix
  • Carrier IDs
  • Dial peers
  • Local IP address
  • Remote IP address
  • Telephony interface or port
  • Trunk groups
Note Note: Call filtering also works on IP-to-IP gateway connections using H.323.

The selected criteria are set on the gateway, and different sets of criteria can be stored.

To better understand the voice call debug filtering on Cisco voice gateways, see the following sections:

Note Note: See the Cisco IOS Debug Command Reference for detailed information about these debug commands.

Generic Call Filter Module

The debug commands described in the Debug Commands that Support Voice Call Filtering support the following voice modules within the voice gateway:

  • CCAPI
  • Dial peers
  • H.323
  • ISDN
  • IVR (Version 2.0 only)
  • MGCP
  • SIP
  • SSAPP
  • TGRAM
  • Voice AAA
  • VTSP

The filtering for these modules is managed by the generic call filter module (GCFM). The filtering conditions are configured in the GCFM, and then the individual modules are informed when a call has to be filtered. The GCFM coordinates between multiple modules to handle filtering conditions.

All modules use the global unique identifier (GUID) to identify an individual call to GCFM. Each call is assigned a GUID and retains the same GUID throughout the entire network and over time. Gateway information and time stamp are embedded in the GUID. GUIDs identify an individual call among the multiple filtered-out calls so that the call can be isolated. For more information about GUIDs and the debug header, see the Debug Command Output on Cisco IOS Voice Gateways.

Activity in the GCFM can be traced using the debug call filter detail and debug call filter inout commands. See the Cisco IOS Debug Command Referencefor more information about these debug commands.

Calling and Called Number Strings

The string pattern for calling and called numbers can be either a complete telephone number or a partial telephone number with wildcard digits, represented by a period (.) character. Each "." represents a wildcard for an individual digit that the originating voice gateway expects to match. For example, if the calling and called number strings is defined as "555....", then any dialed string beginning with 555, plus at least four additional digits, matches this calling or called number.

Table: Symbols Used in Calling and Called Number Strings shows all of the wildcard symbols that are supported in the calling and called number strings.

Table: Symbols Used in Calling and Called Number Strings
Symbol Description

.

Indicates a single-digit placeholder. For example, 555.... matches any dialed string beginning with 555, plus at least four additional digits.

[ ]

Indicates a range of digits. A consecutive range is indicated with a hyphen (-); for example, [5-7]. A nonconsecutive range is indicated with a comma (,); for example, [5,8]. Hyphens and commas can be used in combination; for example, [5-7,9].

Note Note: Only single-digit ranges are supported. For example, [98-102] is invalid.

( )

Indicates a pattern; for example, 408(555). It is used in conjunction with the symbol ?, %, or +.

?

Indicates that the preceding digit occurred zero or one time. Enter ctrl-v before entering ? from your keyboard.

%

Indicates that the preceding digit occurred zero or more times. This functions the same as the "*" used in regular expression.

+

Indicates that the preceding digit occurred one or more times.

T

Indicates the interdigit timeout. The voice gateway pauses to collect additional dialed digits.

Note Note: The period (.) is the only wildcard character that is supported for dial strings that are configured using the answer-address or incoming called-number command.

Table: Number Matching Examples Using Wildcard Symbols shows some examples of how these wildcard symbols are applied to the calling and called number strings and the dial string that results when dial string 4085550199 is matched to the calling or called number. The wildcard symbols follow regular expression rules.

Table: Number Matching Examples Using Wildcard Symbols
Destination Pattern Dial String Translation String After Stripping

408555.+

408555, followed by one or more wildcard digits. This pattern implies that the string must contain at least seven digits starting with 408555.

0199

408555.%

408555, followed by zero or more wildcard digits. This pattern implies that the string must contain at least 408555.

0199

408555+

40855, followed by 5 repeated one or more times.

0199

408555%

40855, followed by 5 repeated zero or more times. Any explicitly matching digit before the % symbol is not stripped off.

50199

408555?

40855, followed by 5 repeated zero or one time. Any explicitly matching digit before the ? symbol is not stripped off.

50199

40855[5-7].+

40855, followed by 5, 6, or 7, plus any digit repeated one or more times.

50199

40855[5-7].%

40855, followed by 5, 6, or 7, plus any digit repeated zero or more times.

50199

40855[5-7]+0199

40855, followed by 5, 6, or 7 repeated one or more times, followed by 0199.

50199

408(555)+0199

408, followed by 555, which may repeat one or more times, followed by 0199.

5550199

In addition to wildcard characters, the following symbols can be used in the calling and called number strings:

  • Asterisk (*) and pound sign (#)-These symbols on standard touchtone dial pads can be used anywhere in the pattern. They can be used as the leading character (for example, *650), except on the Cisco 3600 series.
  • Dollar sign ($)-Disables variable-length matching. It must be used at the end of the dial string.

Exact and Partial Matching

The conditions under each set of call filters are inclusive, so if multiple conditions are specified under a filter, they are all matched. To compare different conditions, create additional filters.

Matching conditions are as follows:

  • Exact match-All related debug output is filtered until all conditions in the match list are explicitly met. This is the best choice for most situations because the output is the most concise.
  • Partial match-No related debug output is filtered until there is a single explicit match failure. As long as zero or more conditions are met, debug output is not filtered. This choice is useful in debugging call startup problems like digit collection, but is not ideal for many situations because of the large amount of debug output that might be generated before matches explicitly fail.

Media and Signaling Streams

Media streams carry voice, video, fax, and data. Examples of media streams are G.711 or G.723 encoded voice streams or fax data. With the voice call debug filter, the media streams are traced for the voice gateway receiving the media stream. Some traces associated with media streams can be filtered, such as SPI-level traces associated with opening and closing the media channels. However, media RTP/RTCP packet-level traces are not filtered.

Signaling streams include both address signaling and supervisory signaling. Examples of signaling streams include H.323 and SIP protocol streams. With the voice call debug filter, the signaling streams are traced for the gateway or endpoint for the signaling stream.

Configuring the Voice Call Debug Filter

To configure the voice call debug filter, perform the following tasks:

Troubleshooting Tips

To verify the conditions that you have set, use the show call filter match-list command. This command displays the criteria set for the specified match list.

What to Do Next

After the conditions are set for the voice call debug, debug commands can be enabled. Proceed to the Enabling Debug for the Set Filtering Conditions.

Enabling Debug for the Set Filtering Conditions

Use the debug command to enable the set conditions to get the filtered output.

Prerequisites

The conditions for the voice call debug filter must be set as described in the Configuring Call-Specific Conditions.

Troubleshooting Tips

To verify debug conditions, use the following commands:

  • show debug
This command displays the debugs that are enabled.
  • show call filter components
This command displays the components that register internally with the filtering module. This command shows which components are registered with the GCFM, which is the internal module that controls which components are filtered.
  • show call filter match-list
This command displays the criteria set for the specified match list. It shows a list of all the match lists, shows which ones are enabled, and shows whether they are enabled for partial or exact matching.

Output Examples for Voice Call Debug Filtering

This section provides configuration examples to match the identified configuration tasks in the previous section:

Exact Match Filtering: Example

When the exact match condition is used for voice call debug filtering, all related debug output is filtered until all conditions in the match list are explicitly met. In the following example, the configuration, enabled debugs, and debug output for a Cisco AS5400 universal gateway are shown.

Partial Match Filtering: Example

When the partial match condition is used for voice call debug filtering, no related debug output is filtered until there is a single explicit match failure. In the following example, the configuration, enabled debugs, and debug output for a Cisco 3745 modular access router are shown. Because partial match is set, the router displays the ISDN debug messages on all calls and displays only the debug vtsp event messages on the specified dial peer, dial peer 1.


Debug Output for Partial Match Filtering
Router# show debug
The following ISDN debugs are enabled on all DSLs:
debug isdn error is             ON.
debug isdn q931 is              ON.   (filter is ON)
Voice Telephony event debugging is on (filter is ON)

In the following output, the show call filter match-list command is used to show which conditions are set for the specified call filter:

Router# show call filter match-list 4
  incoming calling-number 10..
  incoming called-number 50..
  incoming dialpeer 1
 debug condition match-list is set to PARTIAL_MATCH

The following debug output shows ISDN debug messages on all calls, but displays only the debug vtsp event messages on dial peer 1.
