How to Fix Poor Call Quality

Poor call quality can hurt your conversations with prospective families and damage your center's professional image. This article shows you how to diagnose and fix VoIP calling issues in Enrollio, including troubleshooting your devices, internet connection, and software settings.

What is Poor Call Quality?

Poor call quality affects how you communicate with families, your team's productivity, and your overall enrollment success. Common issues include choppy audio, one-way audio where parents can't hear you (or vice versa), and dropped calls in the middle of conversations.

These problems usually stem from internet instability, device interference, or network configuration issues. Because Enrollio uses internet-based calling, even small problems in your local setup can significantly impact call quality.

Why Fixing Call Quality Matters

Resolving call quality issues helps you maintain professional communication with families, reduces frustration for your team, and protects your center's reputation.

  • More Reliable Calls: Fewer dropped calls and smoother conversations with parents
  • Better Family Experience: Families can hear you clearly, building trust from the first call
  • Higher Team Productivity: Your staff spends less time troubleshooting and more time enrolling families
  • Fewer Missed Enrollments: Stable calls prevent communication gaps that could cost you enrollments
  • Professional Image: Crystal-clear audio reflects well on your childcare center

How to Fix Poor Call Quality

Follow these troubleshooting steps to resolve most call quality issues:

1. Use a Wired Internet Connection

Wi-Fi is more prone to packet loss and instability. Connect your computer directly to your modem or router using an Ethernet cable for the most reliable calling experience.

2. Close Bandwidth-Heavy Applications

Streaming services, file downloads, and cloud backups compete with your calls for internet bandwidth. Pause or close these applications during calls with families.

3. Restart Your Router and Modem

Power cycling often fixes minor internet stability issues:

  1. Unplug the power cable from your router and modem
  2. Wait 30 seconds
  3. Plug them back in and wait for full reconnection

4. Update Your Browser or App

Outdated browsers or apps may cause compatibility issues. Make sure you're using the latest version of Google Chrome or the Enrollio desktop app.

5. Use Google Chrome for Web Calling

Google Chrome provides the most stable calling performance with Enrollio. Avoid other browsers or mobile web access when making calls from your computer.

6. Use Headphones with a Built-In Microphone

Headsets reduce echo and improve microphone quality. Avoid using laptop speakers and built-in mics for calls with families—they make you sound unprofessional.

7. Disable Third-Party Browser Extensions

Some browser extensions can conflict with audio settings or consume bandwidth. Try disabling extensions temporarily to see if call quality improves.

8. Check Your Internet Speed

Your internet connection should meet minimum VoIP standards. The recommended minimum is 5 Mbps upload and download speed.

9. Check for Firewall or Port Blocking

Some firewalls block the traffic needed for calling. Ask your IT team to ensure UDP Ports 10000–20000 are open and not blocked by your firewall.

Advanced Troubleshooting: Jitter, Latency & Packet Loss

If basic troubleshooting doesn't resolve your issues, the problem may be related to advanced network metrics. Understanding these terms helps you (or your IT team) identify deeper connectivity problems:

  • Jitter: Irregular delays in how voice data is delivered. Aim for less than 30ms. High jitter causes crackling or robotic-sounding voices.
  • Latency (RTT): The delay between when sound is sent and when it's heard. Target under 150ms. High latency makes conversations feel out of sync.
  • Packet Loss: Lost voice data during transmission. Should always be 0%. Any packet loss causes choppy audio or words cutting out.

Understanding Call Quality Error Messages

Enrollio automatically detects network issues affecting your call quality and displays warnings in real time. These error messages help you quickly identify and fix problems.

Web App Error Messages

During a live call, you may see a call error indicator at the top of your Enrollio dashboard. Here's what each message means:

  • high-rtt: High round-trip time indicates network latency. Calls may sound delayed or out of sync—you might talk over each other.
  • high-jitter: Inconsistent packet delivery. This causes audio crackling or robotic-sounding voices.
  • high-packet-loss: Voice data is being lost during transfer. Calls will sound choppy or cut out completely.

Mobile App Error Notifications

The Enrollio mobile app shows real-time warnings when call quality is compromised. These alerts help you take action—like switching from Wi-Fi to cellular data—before the issue worsens.

  • high-rtt: We detect high round-trip time on this network
  • high-jitter: You could experience choppy audio or crackling noises
  • high-packet-loss: Some audio may be missing or distorted
  • low-mos: Low Mean Opinion Score, indicating poor overall call quality
Pro Tip: If you see call quality warnings on your mobile app, try switching from Wi-Fi to cellular data or moving to an area with better signal strength.

Frequently Asked Questions

Why do my calls sound robotic or distorted?

This is usually caused by high jitter or packet loss. Try switching to a wired internet connection and close any bandwidth-heavy applications running in the background.

Can I make calls over Wi-Fi?

Yes, but a wired Ethernet connection offers more stability and better quality. If you must use Wi-Fi, make sure you have a strong signal and no one else is streaming or downloading large files.

Which browser works best for calling in Enrollio?

Use Google Chrome for optimal compatibility and performance. Other browsers may work but aren't officially supported.

Why can't parents hear me on calls?

Check your microphone input settings and make sure Chrome has permission to access your microphone. Click the lock icon in your browser's address bar to check permissions.
