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.
