Internal DNC vs campaign DNC: what's the difference

VICIdial doesn't keep just one Do-Not-Call list. It keeps two flavors: a system-wide internal list and per-campaign lists. The DNC (do not call) concept is the same either way, a set of phone numbers you must not dial, but where a number lands changes who it blocks. Knowing the difference keeps you compliant without accidentally muting a number across your whole operation.

The internal DNC list is global

The Internal DNC list is one shared list for the whole system. A number on it is blocked no matter which campaign tries to dial it. Think of it as your master suppression list: once a number is here, nobody on any campaign will call it again. This is the right place for a hard, organization-wide "never call this person" instruction.

Campaign DNC is scoped to one campaign

A Campaign DNC list belongs to a single campaign. A number on it is blocked only for that one Campaign, while other campaigns can still reach it. This is useful when someone opts out of a specific offer but is still a valid contact for a different program. You suppress them where it matters and leave them dialable everywhere else.

How a number gets checked

Both lists filter leads in real time as they move into the Hopper, the queue of numbers waiting to be dialed, but only if you've switched DNC checking on for the campaign. When it's active, a number on the relevant list simply doesn't get loaded for dialing.

  A[Lead headed to hopper] --> B{DNC check active?}
  B -->|No| C[Dialed normally]
  B -->|Yes| D{On internal DNC?}
  D -->|Yes| E[Blocked everywhere]
  D -->|No| F{On this campaign DNC?}
  F -->|Yes| G[Blocked for this campaign]
  F -->|No| C

There's also an automatic path. When an agent ends a call with a Disposition whose DNC flag is set to Y, the number is added to the internal and/or campaign-specific list right away. So your DNC lists grow on their own as agents work, not just through manual entry. This matters when you're picking which list to use: if a contact never wants a call from anyone again, the internal list is the safe choice, while a one-program opt-out belongs on that program's campaign list. Choosing the wrong scope either over-suppresses a good number across the whole shop or leaves a number dialable where it shouldn't be.
