Call Redirection Routing Plan for Disaster Recovery

Overview

VOSS Automate provides a set of tools to configure and enable alternate call routing for disaster recovery (DR) from the failure of back-end services. This allows business continuity for end-customers, without service provider engagement.

Note

This feature only supports Oracle SBCs (Session Border Controller) and will provision the required redirection routing entries in the Local Route Table (LRT) of the Oracle SBC.

The feature provides the following:

• An interface to manage DR routing plans

• An interface to enable/disable DR routing plans

• Email notifications to addressees or groups of enabled and disabled DR routing plans

High level administrators with required permissions can expose the necessary interfaces for the models of this feature on menu layouts and ensure user access profiles are updated accordingly:

• relation/dr_routing_plan_rel: manage call redirection routing plans

• view/dr_routing_plan_view: enable/disable call redirection routing plans

The instance of data/EmailHtmlTemplate called DR Activation is the email notification template that by default contains variables:

• {{ pwf.EMAIL.status }}: activated/deactivated

• {{ pwf.EMAIL.plans }}: list of DR plans

The following macro is used when creating the redirection entry and will need to be cloned down and customized to set the value after the @ symbol, as required:

• dr_routing_OracleSBC_NewLine

Manage Call Redirection Routing Plans

If this model interface is available to an administrator, the list of plans is available to manage.

Note

The input form provides an interface to add individual numbers per plan. A separate plan is required for each number to be redirected. (This feature is typically used on a small scale.)

To add or modify a plan:

1. Add or update the DR Plan name and Description.

2. Add the Destination Number in E164 Format

3. Add or update the Network Device List that contains the session-based controller (SBC - device/oraclesbc/) that holds the local routing table configuration. This routing configuration on the SBC is then of a higher priority than any other routing.

   See: Network Device Lists (NDLs).

4. Choose to enter individual Email Addresses and select an Email Group Name from the drop-down list to receive an email notification when a redirection routing plan is activated or deactivated.

   This feature requires the setup of:

   • an SMTP server - see: Add a SMTP Server

   • if used, email groups - see: Email Groups.

5. Select an Incoming Number from the drop-down list that requires redirection.

The Current Activation Status will show if the current plan has been activated or not.

Enable or Disable Call Redirection Routing Plans

If this model interface is available to an administrator, a set of transfer boxes is available to activate or deactivate selected plans that have been created.

1. Choose the operation to be carried out on the selected plans: Enable selected DR plans or Disable selected DR plans

2. In the Plans transfer box, move created plans according to the selected required enable or disable operation.

3. When the operation is saved:

   • Individual updates are made to the SBC available in the NDL: an update per selected plan.

   • If email messaging has been set up, target addressees and groups are sent an email notification of the operations.

   • The Current Activation Status of a redirection routing plan is updated accordingly.
