DNC Sources

The DNC Sources view configures DNC Sources that you can assign to a campaign. DNC Scrubbing is a contact list management feature that compares telephone numbers in a contact list with a list of do-not-call (DNC) numbers. This process flags numbers in the call list so that they are never dialed. Do-not-call lists are acquired from the government entities or using DNC.com, a third-party list cleansing service provided by the Contact Center Compliance Corporation.

Scrubbing is a two-step process:

1. An initial, bulk scrub of the entire contact list is performed first. This typically removes 30-40% of the entries.

2. When the contact list is dialed by a campaign, Dialer performs just-in-time scrubbing to exclude contacts whose DNC status changed between the time the contact list was bulk scrubbed and the time the contact is being dialed.  Just-in-time scrubbing is performed when records are pulled into cache.

It is not uncommon for a list to be dialed for days or weeks, so changes in DNC status should be expected to occur.  Just-in-time scrubbing is intended to remove relatively few numbers while initial bulk DNC scrubbing can remove as many as 40% of the entries in a contact list.

Just-in-time scrubbing is performed for scheduled calls too. Calls to custom numbers that are blocked by a custom DNC source are not logged.
