Imagine you are managing a call center. You have 10 agents but 100 phone numbers to call.

You use an auto dialer that calls multiple numbers simultaneously. Each of your agents call 10 numbers at once.

If two people pick up for that specific agent, the second person to answer doesn’t connect to the agent, because they’re already on
The first call. They just get dead air.

Realistically, you’ll have thousands of numbers to call.

Note: this is illegal.
