# Call quality troubleshooting

> Diagnose and resolve call quality issues including choppy audio, delays, echoes, and dropped calls

## Overview

Most Quo, formerly OpenPhone, calls deliver crystal clear audio, but connection or device issues can occasionally affect call quality. This comprehensive guide helps diagnose and resolve common audio problems to ensure optimal call experiences.

<Note>
  Call quality issues are often caused by network jitter, device settings, or hardware positioning. Most problems can be resolved with [simple troubleshooting steps](https://support.quo.com/core-concepts/calling/call-quality-metrics#quick-fixes-based-on-what-you%E2%80%99re-hearing).

## Common call quality issues

<AccordionGroup>
  <Accordion title="Audio is choppy, robotic, or breaking up during calls">
    **Symptoms:**

    * Audio "breaking up" or cutting out
    * Robotic or distorted voice quality
    * Intermittent sound drops

    **Primary cause:** [Jitter](https://www.quo.com/blog/what-is-jitter/) in your internet connection affects audio data packets, causing packet loss and degraded audio quality.

    **Quick fixes:**

    1. Reset internet router and wait 60 seconds
    2. Switch from WiFi to cellular data or vice versa
    3. Close background applications consuming CPU resources
    4. Try different device (mobile vs desktop)
    5. Contact support if issue persists with one contact only
  </Accordion>

  <Accordion title="One party cannot hear the other during calls">
    **Symptoms:**
