Configure a Custom DNC Source

To use a custom table in the Dialer database as a DNC Source:

  1. In Interaction Administrator, expand the Advanced Interaction Dialer container. Then select the DNC Sources container.

  2. Click Add to create a new entry.

  3. Enter a descriptive name in the Name field.

  4. Set Type to Custom. This indicates that you want to define the source using a table in Dialer's database that contains do-not-call numbers.

  5. Use the Connection drop list to select a database connection.

  6. Use the Table drop list to select the name of the table that contains the list of DNC numbers. These are the telephone numbers that will be used later to scrub contact lists.

  7. Specify which column in that table contains the blocked numbers. Use the Phone Number Column drop list to select the name of the column that contains telephone numbers.  All the numbers in the DNC data source must be in the same format, e.g. (xxx) xxx-xxxx, and the numbers in the contact list must also be in that same format (Varchar), so that no normalization has to be done.

    Important: The data type of the phone number column of the table used as a custom DNC source must be of type Varchar. If a column of a different data type is used, the bulk scrub will fail and Dialer will warn: "Bulk scrubbing failed due to an internal Dialer error".

  8. You must assign a value to "Phone Number Column", "Database Column to Exclude" or both:

    • Select a column from the Database Column to Exclude list. A campaign can be configured to match a contact list column against an additional column in the custom DNC table. This drop list selects a column in the DNC table that DNC processing will be compare to a similarly named column in the contact list, for the purpose of not dialing matching records. These columns might store account numbers, for example. When there is a match, Dialer will not call any phone number in the matching account.

      And/Or

    • Select an Expiration Column. This identifies an expiration date-time column in the DNC table, after which time the DNC entry is ignored or deleted. If a campaign is configured to use this DNC source, the time in the DNC column is compared with the current time.

      If the current time is previous to the expiration time, the number is not dialed. It is treated like a traditional do-not-call number.

      If the current time is past the expiration time, the number is dialed because the entry has expired.

  9. Click Save to save changes.

  10. At this point you have configured a DNC source. The next step is to Configure a Campaign to use a DNC Source.

  11. Afterward you can perform an initial bulk scrub of the campaign's contact list.
