Inbound calls happen when a customer, client, or other individual calls into an organization. For instance, these are examples of inbound calls – if you call a customer service department for help, dial a phone number to place an order after seeing an offer on TV, or make a call to a business to schedule an appointment. These are considered inbound calls, because the phone rings in the call center to initiate the conversation. Basically, an inbound call is when a company receives a phone call from a customer.
