Dial Plan Models

To access the latest documentation, go to Documentation and Resources at: https://voss.portalshape.com

Dial plan models (default menu: Dial Plan Management > Dial Plan Model) allow you to define the dial plan and to enter a name and type to group its elements.

The Dial Plan Type drop-down is used to tag it with its hierarchy, so that available dial plans to push or remove are filtered when using the Dial Plan Maintenance menu:

• Multi-tenant / Shared Architecture - provider hierarchy
• Global - customer hierarchy
• Site - site hierarchy

A description and notes for the Dial Plan Model definition can be added on the input form.

Dial Plan Model Elements

The remaining list of menus manage elements of dial plans created with the feature. Individual elements such as Route Patterns, SIP Trunks, and Translation Patterns each have a menu item from which it can be associated with a Dial Plan Model and managed.

The feature provides menu items or input fields to extend schema based dial plan management functionality. When a dial plan created with the feature is pushed from the Dial Plan Maintenance menu, the transaction log can be inspected to see the extended functionality:

• Device Pools - Regions - Locations -SRST
• Transcoders
• Conference Bridge
• Media Resource Groups
• Media Resource Group Lists
• Route Groups
• SIP Trunks
• CTI Route Points with Lines (Lines are not supported in schemas)

When managing these dial plan elements, the installed named macros can be used to refer to data added from the Dial Plan Input Data menu.

The list view from each of these menus shows the Dial Plan Name - as defined from the Dial Plan Model menu - to which the element belongs. The feature structures the elements as instances of distinct data models.

There is an additional flexibility in the Route Patterns and Translation Patterns dial plan model elements so that a Local Dialing check box can be selected here if required when using a simpler or flat dial plan.

Dial Plan elements, such as Calling Search Space, can be cloned and edited to easily add another element to the dial plan by defining an "add-on" dial plan model, associating the cloned CSS element with it and pushing it to the required Call Manager cluster using the Dial Plan Maintenance menu. In this way the dial plan can be then be updated - functionality that is not possible in a schema based approach.

Additional workflows in the feature allow for values (for example MRGL) to be added from for example the Device Pools - Regions - Locations -SRST element input form, since the workflow will push to the these to the Call Manager cluster only after the prerequisite values become available. Inspect the transaction log to see the required sequence of data carried out with these workflows.
