# 1. Setup your calling operations

{% hint style="info" %}
**‘Calling Operations’ are day-to-day calling use-cases of a Department. These are pre-defined to help your business with a quick setup.**

**A ‘Department’ is an autonomous business unit that can have multiple calling operations inside it. If your business has multiple units or has subsidiary businesses with similar calling operations, having different departments gives a clear picture of each respective calling metrics and helps to keep your business numbers and their feature sets properly segregated.**
