# Phonebook

The Phonebook module lets you build and manage outbound call campaigns at scale.

**Core Concept**

Use Phonebook to:

* Create contacts and groups
* Launch outbound voice campaigns

**Workflow Overview**

1. Go to Phonebook in the sidebar
2. Upload contacts via CSV or add manually
3. Assign contacts to a group (e.g., "Medical Leads," "Insurance Renewals")
4. Launch the campaign by calling a specific group.

Phonebook gives you full control over outbound strategy, agent pairing, and campaign pacing. It’s ideal for scaling voice outreach without manual dialing or scripting.
