Overview of Multiple Destination Pattern Support on a Voice Dial Peer

On Cisco Unified Border Element (Enterprise) and Session Initiation Protocol (SIP) Gateway, one VoIP dial peer can have only one destination pattern. To support multiple destination patterns on a VoIP dial peer, which involve massive dial peer configuration, use an E.164 destination pattern map. You can create a destination E.164 pattern map and then link it to one or more dial peers. A destination pattern, which is associated with a dialed string on a specific telephony device, is configured on a VoIP dial peer by using the destination e164-pattern map command. When a dialed string on a telephony device matches the destination pattern, calls are routed on to the VoIP dial peer; otherwise the call fails. You must configure an E.164 destination pattern map for each VoIP dial peer that is defined on a device. Configuring an E.164 destination pattern map on multiple dial peers requires several configurations as compared to configuring a destination pattern map on a single dial peer.

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

When a dial peer has multiple destination patterns, select the longest prefix matching criteria to count as the pattern matched for the dial peer. For example, if dial peer A has two destination patterns matched where one destination pattern is matched with five digits and the other destination pattern is matched with four digits, then dial peer A is counted as matched with five digits.

12.   show dial-peer voice

13.   show voice class e164-pattern-map [summary | tag]


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 tag


Example:

Device(config)# voice class e164-pattern-map 11

 

Creates an E.164 pattern map to configure multiple destination E.164 patterns on a dial peer and enters voice class E.164 pattern map configuration mode.

 
Step 4
url url


Example:

Device(config-voice class e164-pattern-map)# url http://http-host/config-files/destination-pattern-map.cfg

 

Defines the URL of an internally or an externally stored text file used in the E.164 pattern map.

Note    If you are using the url command, skip Step 5 and proceed to Step 6.
 
Step 5
e164 pattern


Example:

Device(config-voice class e164-pattern-map)# e164 5557123

 

Defines a complete E.164 telephone number prefix.

 
Step 6
description string


Example:

Device(config-voice class e164-pattern-map)# description It has 3 entries

 

Provides a description for a specific E.164 pattern map.

 
Step 7
exit


Example:

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

 

Exits voice class E.164 pattern map configuration mode and enters global configuration mode.

 
Step 8
dial-peer voice tagvoip system


Example:

Device(config)# dial-peer voice 123 voip system

 

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

 
Step 9
destination e164-pattern-map tag


Example:

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

 
Links an E.164 pattern map to one or more dial peers.
  • Identifies a destination E.164 pattern map associated with a dial peer with a number assigned to the destination E.164 pattern map. The range is from 1 to 10000.
Note    Repeat the Steps 1 to 9 to add multiple destination E.164 patterns to a pattern map.
 
Step 10
end


Example:

Device(config-dial-peer)# end

 

Exits dial peer configuration mode and enters privileged EXEC mode.

 
Step 11
voice class e164-pattern-map loadtag


Example:

Device# voice class e164-pattern-map load 2543

 

Loads a destination E.164 pattern map that is specified by a text file.

 
Step 12
show dial-peer voice


Example:

Device# show dial-peer voice

 

Displays the status of an E.164 pattern map when the pattern map is associated with a dial peer.

 
Step 13
show voice class e164-pattern-map [summary | tag]

Example:

Device# show voice class e164-pattern-map 11

 

Displays the status of the configured E.164 pattern maps and the status of the text file.

  • Also displays the status and the content of a particular E.164 pattern map.

Multiple Destination Pattern Support on a Voice Dial Peer

15.2(4)M

The Multiple Destination Pattern Support on a Voice Dial Peer feature is used for handling calls that have noncontiguous dial patterns. This feature allows you to create an E.164 pattern map with multiple destination E.164 pattern, which helps to define and configure destination patterns on an individual dial peer or multiple dial peers.

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.
