An outbound call center is the exact opposite of an inbound call center. Rather than having a majority of your calls come in to your call center, agents in outbound call centers are, for the most part, making outgoing calls.
This definition means that most outbound call centers are sales focused. When agents are making phone calls out of the call center, they’re focused on a list of customers or potential customers that they’d like to get in touch with. Most of the time, this means that they’re targeting them for a sale.
