# Call Quality Issues

> Troubleshoot and optimize call quality, latency, and connection issues

Call quality can be affected by both technical factors and AI settings. Here's how to optimize both:

## AI Engine Impact

Your choice of AI engine affects perceived call quality:

### Fast Engine + Filler Audio

* Minimal latency
* Quick back-and-forth
* Natural conversation flow
* Best for most calls

### Standard/Accurate Engine

* Longer processing time
* More accurate responses
* Better for complex conversations

## Optimization Tips

* Start with Fast Engine + Filler Audio
* Switch to Standard/Accurate only if needed
* Monitor call recordings for quality
* Test different voice models

## Quick Fixes

If experiencing issues:

1. Try a test call
2. Switch to a faster engine setting
3. Enable filler audio
4. Check network connection

**Tip:** The combination of Fast Engine and Filler Audio typically provides the best perceived call quality.
