Multiple Pattern Support on a Voice Dial Peer

Overview

The Multiple Pattern Support on a Voice Dial Peer feature enables you to configure multiple patterns on a VoIP dial peer using an E.164 pattern map. A dial peer can be configured to match multiple patterns to an incoming calling or called number or an outgoing destination number.

Matching an incoming or outgoing call using a pattern defined in a VoIP dial peer is an existing feature on the Cisco Unified Border Element (Enterprise) and Session Initiation Protocol (SIP) Gateway. You can now support multiple patterns on a VoIP dial peer using an E.164 pattern map. You can create an E.164 pattern map and then link it to one or more VoIP dial peers.

When a pattern is the only source to enable a dial peer, a valid E.164 pattern map enables the linked dial peers, whereas an invalid E.164 pattern map disables the linked dial peers. Additionally, whenever an E.164 pattern map is created or reloaded, one or more dial peers linked with an E.164 pattern map is enabled or disabled based on the validation of a pattern map.

You can match a pattern map to an incoming calling or called number or an outgoing destination number.

When a dial peer has multiple patterns, the pattern with the longest prefix is considered as the matching criteria.

Configuring Multiple Pattern Support on a Voice Dial Peer (Inbound Calls)

Cisco IOS 15.4 (1)T

Cisco IOS XE 3.11S

This feature was extended for inbound VoIP dial peers for incoming calling and called numbers.

Configuring Multiple Pattern Support on a Voice Dial Peer (Outbound Calls)

Cisco IOS 15.2(4)M

This feature allows you to add more than one E.164 destination pattern inside a pattern map and configure that pattern map for one or more VoIP dial peers.

This feature is supported for outbound peers only.

The following commands were introduced or modified: destination e164-pattern-map , e164 , show voice class e164-pattern-map , url , voice class e164-pattern-map load , voice class e164-pattern-map .

Restrictions for Multiple Pattern Support on a Voice Dial Peer

  • This feature is supported only on a VoIP dial peer.

  • Duplicate patterns cannot be added to a pattern map.

Configure Multiple Pattern Support

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. voice class e164-pattern-map pattern-map-id
  4. Do one of the following:
    • e164 pattern-map-tag
    • url url
  5. (Optional) description string
  6. exit
  7. dial-peer voice dial-peer-id voip
  8. {destination | incoming called | incoming calling} e164-pattern-map pattern-map-group-id
  9. end

  11. show dial-peer voice [summary | dial-peer-id]

DETAILED STEPS

  Command or Action Purpose

Step 1

enable

Example:


Device> enable

Enters privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Device# configure terminal

Enters global configuration mode.

Step 3

voice class e164-pattern-map pattern-map-id

Example:


Device(config)# voice class e164-pattern-map 1111

Creates a pattern map for configuring one or multiple E.164 patterns on a dial peer and enters voice class configuration mode.

Step 4

Do one of the following:

  • e164 pattern-map-tag
  • url url

Example:

Using URL text file: 


Device(voice-class)# url http://http-host/config-files/pattern-map.cfg

Directly specifying match patterns: 


Device(voice-class)# e164 5557123

Configure one or more E.164 telephone number prefix match patterns for the pattern map.

  • Repeat this step for each pattern if you are using the e164 command.

  • You can specify a file URL containing the patterns for this dial peer using the url url command. You must then load the E.164 telephone prefixes using Step 10. The file can be internal (on the device) or external.

Step 5

(Optional) description string

Example:


Device(voice-class)# description It has 1 entry
(Optional)

Provides a description for the pattern map.

Step 6

exit

Example:


Device(voice-class)# exit

Exits voice class configuration mode and enters global configuration mode.

Step 7

dial-peer voice dial-peer-id voip

Example:


Device(config)# dial-peer voice 2222 voip

Defines a VoIP dial peer and enters dial peer configuration mode.

Step 8

{destination | incoming called | incoming calling} e164-pattern-map pattern-map-group-id

Example:


Device(config-dial-peer)# incoming calling e164-pattern-map 1111

Links a pattern-map group with a dial peer.

  • Use the destination keyword for outbound dial peers.

  • Use the incoming called or incoming calling keywords for inbound dial peers using called or calling numbers.

Step 9

end

Example:


Device(config-dial-peer)# end

Exits dial peer configuration mode and enters privileged EXEC mode.

Step 10

(Optional) voice class e164-pattern-map load pattern-map-group-id

Example:


Device# voice class e164-pattern-map load 1111
(Optional)

Loads the specified pattern map with E.164 match patterns from a text file configured in the pattern map.

  • This step is required only if patterns have been defined for the specified pattern map using a file URL in Step 4.

Step 11

show dial-peer voice [summary | dial-peer-id]

Example:


Device# show dial-peer voice 1111

Displays the status of a pattern map when the pattern map is associated with a dial peer.

SUMMARY STEPS

  1. show voice class e164-pattern-map [summary | pattern-map-id]
  2. show dial-peer voice [summary | dial-peer-id]
  3. show dialplan incall {sip | h323} {calling | called} e164-pattern

DETAILED STEPS

Step 1

show voice class e164-pattern-map [summary | pattern-map-id]

Displays the status and contents of a specified pattern map or a status summary of all pattern maps.

Example:

Device# show voice class e164-pattern-map 200

e164-pattern-map 200
-----------------------------------------

        incoming calling e164-pattern-map tag = `200' status = valid,
        destination e164-pattern-map tag = 3000 status = valid,

Device# show dial-peer voice 2222| include  e164-pattern-map

        incoming calling e164-pattern-map tag = `200' status = valid,

Step 3

show dialplan incall {sip | h323} {calling | called} e164-pattern

Displays inbound dial peer details and associated pattern maps based on an incoming calling or called number.

Example:

Device#  show dialplan incall voip calling 23456
