Overview

Push notifications are essential for Quo, formerly OpenPhone functionality, alerting you to incoming calls, messages, and other important events. When notifications fail, you may miss critical communications. This guide helps restore reliable notification delivery across all devices.
Push notifications require proper permissions on all devices. Different issues may require platform-specific solutions for iOS, Android, web, and desktop applications.

​
Understanding notification issues

Call notifications:
  • Incoming call alerts with caller information
  • Missed call notifications with timestamps
  • Call connection status updates
  • Voicemail arrival alerts
Message notifications:
  • New text message alerts with previews
  • Message delivery confirmations
  • Group message updates
  • MMS arrival notifications
System notifications:
  • Account status updates
  • Service announcements
  • Billing and subscription alerts
  • Security notifications
Different problem types:
  • No notifications: Not receiving any push alerts
  • No ringing: Getting missed call notifications but no live ring
  • Delayed notifications: Receiving alerts late
  • Partial notifications: Some alerts work, others don’t
If you receive missed call notifications but don’t hear incoming calls ring, see the Connection Issues guide for call-specific troubleshooting.
Quick diagnosis:
  • If you see missed calls but never heard ring = Ringing issue
  • If you don’t see any alerts at all = Notification issue
  • If alerts arrive late = Network or device performance issue

​

Diagnostic checklist:
  • Frequency: Do notifications never work or work intermittently?
  • Platform specific: Issues on one device type or all platforms?
  • Timing patterns: Problems at specific times or consistently?
  • Content types: Some notification types work while others don’t?
What results mean:
  • No notifications ever = Permission or setup issue
