Why is Your GoHighLevel Call Quality Bad?

Poor call quality in GoHighLevel can disrupt your sales, support, and client communication. Issues like robotic voices, dropped calls, or delays often stem from your internet connection, device setup, or browser environment. By systematically addressing these common culprits, you can restore clear and professional audio for all your calls. Resolving these problems not only enhances your communication but also boosts team efficiency and protects your brand's reputation. A stable calling environment ensures your team can focus on engaging leads rather than battling technical issues.

1
Use a Wired Internet ConnectionConnect your computer directly to your modem or router using an Ethernet cable. Wi-Fi connections are more prone to signal drops and packet loss, which severely impact VoIP call quality.
2
Check Your Internet Speed and StabilityVisit a site like SpeedTest.net to test your upload and download speeds. You need a minimum of 5 Mbps for both upload and download to ensure clear VoIP calls without interruption.
3
Close Bandwidth-Heavy ApplicationsShut down any applications that consume significant internet bandwidth, such as streaming services, large file downloads, or cloud backup processes. This frees up crucial resources for your GoHighLevel calls.
4
Restart Your Router and ModemUnplug the power cables from both your internet modem and Wi-Fi router. Wait for at least 30 seconds before plugging them back in, then allow them to fully reconnect to the internet. This can resolve minor network glitches.
5
Update Your Browser or GoHighLevel AppEnsure your Google Chrome browser or the GoHighLevel desktop application is updated to its latest version. Outdated software can create compatibility issues that degrade call performance and audio quality.
6
Use Google Chrome for Web CallsAlways make calls from the GoHighLevel web app using Google Chrome. It provides the most stable and optimized VoIP performance, minimizing issues compared to other browsers or mobile web access.
7
Utilize a Headset with a Built-In MicrophoneUse a quality headset that includes a microphone for all your professional calls. Headsets significantly reduce background noise, prevent echo, and deliver clearer audio than laptop speakers and built-in mics.
8
Disable Third-Party Browser ExtensionsTemporarily disable any browser extensions or third-party software that might interfere with audio settings or consume bandwidth. This helps isolate conflicts that could be causing poor call quality.
9
Check Firewall or Port Blocking SettingsIf you are on a managed network, ask your IT team to ensure that UDP Ports 10000–20000 are open. Some firewalls might block these ports, which are essential for SIP (VoIP) traffic.

Understanding GoHighLevel Call Quality Indicators

GoHighLevel provides real-time indicators during calls to help you pinpoint the exact nature of any audio problems. Understanding these terms and alerts allows you to quickly diagnose and address underlying network issues, whether you're using the web app or mobile app. These warnings appear at the top of your dashboard during a live call. By recognizing these indicators, you can take immediate action—like switching networks or closing apps—to prevent further call degradation and ensure a smoother conversation.

1
Identify 'high-rtt' (High Round-Trip Time)This indicator means there's a significant delay between when a sound is sent and when it's received. You might experience calls where audio feels out of sync or delayed, making conversations awkward. Aim for an RTT under 150ms.
2
Recognize 'high-jitter' (Inconsistent Packet Delivery)Jitter refers to irregular delays in how voice data packets arrive. When jitter is high, calls can sound robotic, crackly, or choppy, making speech difficult to understand. Target a jitter value of less than 30ms.
3
Spot 'high-packet-loss' (Lost Voice Data)Packet loss means some parts of your voice data are not reaching their destination. This results in calls where words or entire phrases cut out, making the conversation incomplete and frustrating. Packet loss should always be 0% for clear audio.
4
Interpret 'low-mos' (Low Mean Opinion Score)A 'low-mos' warning indicates poor overall call quality, often a result of combined issues like high RTT, jitter, or packet loss. This is a general alert that your call experience is significantly degraded.
🔥 Pro Tip

If you see a quality indicator, try pausing your call briefly to implement a quick fix, like closing a background app or switching to a wired connection, before resuming.

Troubleshooting Common Issues

⚠️ My calls sound robotic, crackly, or choppy.
This usually points to 'high-jitter' or 'high-packet-loss'. Ensure you are using a wired internet connection, close all unnecessary background applications, and update your browser.
⚠️ There's a noticeable delay in my calls, or I hear an echo of my own voice.
This is often caused by 'high-rtt' (latency). Verify your internet connection's stability and speed. For echoes, ensure you are using a quality headset with a built-in microphone.
⚠️ The other person can't hear me, or my audio cuts out completely.
First, check your microphone input settings on your computer and within Google Chrome's site permissions. If settings are correct, investigate 'high-packet-loss' issues by restarting your router and modem.
⚠️ My GoHighLevel calls frequently drop or disconnect.
Dropped calls often indicate severe network instability. Restart your modem and router, confirm a strong, wired internet connection, and ensure your browser or GoHighLevel app is fully updated.
⚠️ I see a 'low-mos' warning, but no specific error code.
A 'low-mos' indicates general poor call quality. Systematically go through all the troubleshooting steps outlined above, focusing on network stability, device setup, and browser optimization.

Common Mistakes to Avoid

  • Relying solely on Wi-Fi instead of a more stable wired Ethernet connection for calls.
  • Not using a dedicated headset with a microphone, leading to echoes and poor audio input.
  • Keeping multiple bandwidth-intensive applications open in the background during calls.
  • Using an outdated version of Google Chrome or the GoHighLevel desktop application.
  • Ignoring the real-time call quality indicators within GoHighLevel, delaying diagnosis.

Frequently Asked Questions

QWhy do my calls sound robotic or distorted in GoHighLevel?
Robotic or distorted audio in GoHighLevel calls is typically a sign of 'high-jitter' or 'high-packet-loss' on your network. Jitter causes inconsistent delays, while packet loss means parts of your voice data are lost. To fix this, switch to a wired Ethernet connection, close any background applications consuming bandwidth, and ensure your internet speed meets the minimum requirements. Updating your browser can also help resolve these issues.
QIs it better to use a wired internet connection or Wi-Fi for GoHighLevel calls?
It is significantly better to use a wired internet connection (Ethernet) for GoHighLevel calls. Wi-Fi is more susceptible to interference, signal drops, and packet loss, which can severely degrade VoIP call quality. A wired connection provides a stable, consistent, and faster data flow, ensuring clearer audio and fewer interruptions for professional communication.
QWhich web browser is recommended for making calls within GoHighLevel?
Google Chrome is the recommended web browser for making calls within the GoHighLevel web application. GoHighLevel's VoIP features are optimized for Chrome, offering the most stable performance and compatibility. Always ensure your Chrome browser is updated to its latest version to prevent any software-related audio issues and ensure the best possible call quality.
QWhat should I do if the GoHighLevel app shows a 'high-rtt' warning during a call?
A 'high-rtt' warning indicates high round-trip time, meaning there's a delay in your network connection causing audio to sound out of sync. To address this, first, restart your modem and router to refresh your network. Close any background applications that might be consuming bandwidth. If possible, switch to a wired internet connection. Ensure your internet service provider isn't experiencing outages or congestion in your area.
QMy microphone isn't working during GoHighLevel calls. What should I check?
If your microphone isn't working during GoHighLevel calls, start by checking your computer's sound settings to ensure the correct microphone is selected as the input device. Next, verify that Google Chrome or the GoHighLevel desktop app has permission to access your microphone. You can usually find this in your browser's site settings or your operating system's privacy settings. Also, test your headset on another application to rule out a hardware issue.
