## Finosu Concepts

At Finosu, we have three main concepts: customers, scheduled calls, and calls.

### Customers

Customers are the entities that you want to service. You can add customers
via the API.

### Scheduled Calls

Scheduled calls represent calls that will be potentially executed or calls that have been executed by the system.
The status designates which ones they are. You can create a series of scheduled calls for a customer, but the
the system will handle the schedule time based on the type passed.
A customer can only have one active call schedule at a time. If you generate a new schedule,
it will deactivate any existing ones and activate the new schedule.

### Calls

Calls represent calls that have been executed. Each call includes a transcript, recording URL, and post-processing flags that indicate
events and outcomes from the conversation (such as DNC requests, complaints, voicemail messages, etc.)
