## DNC

If administrator wants to exclude few numbers that should not be dialed in the system, then they can be uploaded in DNC tab by adding leads. Adding numbers at the system level will apply DNC on those numbers at tenant level. They will not dial through any of the campaign or queues created under that tenant from Auto-Dial.
