# Blocking contacts
> Block unwanted callers and manage your blocklist to protect your time from spam and unwanted communications
## Overview
Blocking unwanted contacts helps protect your time and maintain a professional communication environment. Quo, formerly OpenPhone's blocking features allow you to prevent spam calls and messages while maintaining full control over your blocklist for easy management.
## Understanding blocking
When you block a contact in Quo:
* **Calls are silenced**: Blocked numbers cannot reach you by phone
* **Messages are filtered**: Text messages from blocked contacts are hidden from your inbox
* **Team protection**: Blocked contacts are prevented from reaching your entire team
* **Easy reversal**: You can unblock contacts at any time through your blocklist
Blocked conversations are moved out of your main inbox but remain accessible through your blocklist for reference.
