Overview

As part of the Wrangler WxC-DI Migration Dial plan Type Template - an option exist to select SDP (Simplified Dial Plan). This will enable the push of a Simplified country dial plan to the target WxC-DI server. The Source CUCM Dial Plan objects are then mapped to the pre provisioned dial plan and device objects transformed and migrated

The dial plan is created in wrangler using templates and libphone library. A dialplan instance will be automatically created / country and sites, then pushed by Wrangler to the target as part of the migration

The existing SDP templates part of the Default Schema in Wrangler may be freely modified or new created as required.

Migration with SDP Dial Plan

The process to initiate a migration with SDP is the same as to initiate any migration with Wrangler. Selections as per below screenshot, then follow normal migration process here wrangler_ WxC-DI Migration User Guide | Template Dialplan Migration (Push Dialplan From Templates)

Dial Plan Functionality

The SDP creates a Dialplan in target that uses a single loop prior to routing calls. All Dial Prefixes for supported call types are created by Wrangler SDP as Translation Patterns.

For every external call, numbers dialed match a TP (Translation Pattern) entry depending on COS. The TP strips the prefix and add routing prefix using calling parties CSS, pointing to a Route pattern that in turn selects appropriate RL to route the call

Call Flow Sample below

1. DN 35100 dials 912343555555

2. Line has CSS C01S02USA-NationalCLIP-CSS that contains RP USA-Natl-PT

3. This matches a TP 91.23[149][2-9]XXXXXX which strips predot (91) and prefixes **021 Creating new number **0212343555555 using original DN 35100’s CSS

4. This new number matches Route Pattern **02.! in USA-NatlCLIPRtg-PT (This RP part of DN35100 CSS) This Route pattern strips predot (**02) and prefixes with + creating number +12343555555 routing it to RL USA-Natl-RL allowing CLIP

Call Types

Whilst the default schema for SDP only utilise some Call Types, the following Call Types are supported

• National

• Mobile

• Local

• International

• Premium

• TollFree

• Service

• Personal Comm Service

• Emergency

• Special Rate Service

• Operator Service

Dial Plan Objects Created

As mentioned above using libphone library, call types and templates, The SDP will create a basic dial plan including dial out prefixes, country dial plan translation patterns allowing for COS, blocking, CLIP/CLIR and routing in the target supporting a number of call types with the following objects

• CSS’s

• Route Partitions

• Translation Patterns

• Route Lists

• Route Groups (Trunk/ GW’s need to be added to RG’s as required)

• Route Patterns

Templates Explained

The templates uses macros to create the required dialplan objects in the target. To explain how the templates are built we use the preview function, further explained later on this page. The template used here is the National call type for USA. Note that whilst the template will generate multiple entries in CUCM (one for each national dial prefix), the preview will only display one of them.

Corresponding WxC-DI output for above template

CSS’s

Calling search spaces are created for COS and routing.

There are COS for Internal Only created/ cluster and country, National, International and Premium calling with CLIR or CLIP created/ site

Route Partitions

Route partitions are created to support COS including Blocking partitions, routing partitions, partitions for all call types with CLIP and CLIR

Translation Patterns

The TP’s are the core of the SDP. The Wrangler schema templates using libphonenumber library, creates a set of TP Dialplan prefix entries for each call type for the nation selected in the target CUCM.

The Sample template below will generate a set of TP entries for national US prefixes

Route Lists

The Route List SDP templates will create a RL / country. The SDP will create a set of Route Lists for Each type National, International and Services Routes for each country supported by cluster.

Below template will create a RL with selected RG for CBO

Route Groups

Same as Route Lists above, SDP will create a Set of Route Groups for National, International and Services for each country supported. Any trunks/ GW\s for the RG’s will need to entered manually as required.

Route Patterns

A set of Route Patterns are created by SDP to support Each of National, International and Services trunk routing for each of CLIP and CLIR and individual country

Modifying the Dialplan Templates

The existing Dial Plan templates may be modified or new ones created as required. They may be modified ‘globally’ or they may be modified on a per migration basis.

Global Template Creation and modification

To modify templates globally requires that existing Default Schema is Cloned and downloaded. To do this, select Schemas, then Default Schema from menu

Next create Clone by selecting +Clone Schema, name the clone and +Clone

The newly created clone can now be modified as required. To narrow down the view, select Filter All Groups → simplifiedDialplan, which will show all the SDP templates

From here, any of the existing SDP templates may be selected and modified as required by selecting the individual template in the Name column.

If we for example wanted to view/ modify template that creates TP’s with country national prefixes, we select SDP - TransPattern - Country CallType Pattens National Fixed Line voip which brings up below display

To the left of the screen we have template attributes which determines how the template will be used and to the right the template fields with macros

When any changes have been completed, select Save Changes

To use the new modified schema in a migration - when initiating a new migration, select the new schema rather than Default Schema

Changing Template per migration

Templates may also be modified/ per migration. To do this, within migration, select Schema → Templates

Then from All Groups filter select simplifiedDialplan

from here select the Template that should be viewed/ modified. In below screenshot we have selected

SDP - TransPattern - Country CallType Patterns National Fixed Line voip

To Modify any field in the template as required, you select Overview Template, modify as required, then Save Changes. There is here a preview option that shows the output from modification for testing before deploying

To use the preview function, select Preview Template then select required options and Generate Report

This will show the template and the output of the template for verification
