NDM Block

Starting with Composer release 8.1.410.14, callflow diagrams add an NDM block to work with Nuance OSDM 6.1 modules used for speech and touch-tone IVR applications. The NDM block, available on the Server-Side palette, lets you choose the OSDM modules and parameters to work with the selected module.

Note: Composer has a template Project that uses Subdialog blocks to invoke OSDM modules. This new block provides in-built support to work with OSDM modules.

Global Properties

Output Result Property

You must use the Output Result property to assign the collected data to a user-defined variable for further processing.

Important

Note! This property is mandatory. You must select a variable for the output result even if you do not plan on using the variable. If this is not done, a validation error will be generated in the Problems view.

1. Select the Output Result row in the block's property table.

6. From the Expression field, click the button to use Expression Builder where you can define an expression for the input parameter(s) or select a variable containing the expression (Callflow Variables > Input).
7. Set the "browser" parameter to genesys. This is optional but helpful as this parameter directs the engine to match the Voice Platform type.
8. In the Description field, type a description for this parameter.
9. Click Add again to enter another parameter, or click OK to finish.

Security Property

When the Security property is set to true, data for this block is treated as private. GVP will consider the data associated with this block as sensitive and will suppress it in platform logs and metrics. To assign a value to the Security property:
