Common Causes of Poor Call Quality

Understanding the root causes of call quality issues helps you quickly identify and resolve problems. Poor call quality typically manifests as choppy audio, static noise, echo, delays, or dropped connections.

Insufficient Bandwidth, Low internet speeds or network congestion can cause audio to drop or become distorted during calls.Browser Issues, Outdated browsers, excessive extensions, or browser cache problems can interfere with call performance.Hardware Problems, Malfunctioning microphones, speakers, or headsets can produce poor audio quality or fail to transmit sound properly.Network Configuration, Firewall settings, router configurations, or Quality of Service (QoS) settings may block or deprioritize voice traffic.High CPU Usage, Running multiple resource-intensive applications simultaneously can reduce available processing power for calls.2

Check Your Internet Connection

A stable, high-speed internet connection is essential for clear voice calls. Open Doors requires consistent bandwidth to transmit audio data in real-time without interruptions.

Step 1Test Your Internet Speed

Visit a speed testing website (such as Speedtest.net) and run a test. For optimal call quality, you need at least 1 Mbps upload and 1 Mbps download speed, though 5 Mbps or higher is recommended.

Step 2Use a Wired Connection

If you're using WiFi, try switching to a wired Ethernet connection. Wired connections provide more stable speeds and reduce the risk of interference or signal drops.

Step 3Close Bandwidth-Heavy Applications

Pause downloads, close streaming services, and exit video conferencing tools that aren't needed. These applications compete for bandwidth and can degrade call quality.

Step 4Restart Your Router

Unplug your router for 30 seconds, then plug it back in. This clears temporary network issues and can improve connection stability.

Note

If multiple users share your network, their activity can impact your call quality. Consider scheduling important calls during off-peak hours or upgrading your internet plan.

Optimize Browser Settings

Browser configuration plays a critical role in call performance. Outdated browsers, cache buildup, and conflicting extensions can all interfere with audio transmission.

Step 1Update Your Browser

Ensure you're using the latest version of Google Chrome, Firefox, Edge, or Safari. Open Doors works best on up-to-date browsers with current security and performance features.

Step 2Clear Browser Cache and Cookies

Access your browser settings and clear browsing data, including cached images and cookies. This removes corrupted files that may interfere with call functionality.

Step 3Disable Browser Extensions

Try disabling all browser extensions temporarily, then make a test call. Extensions like ad blockers, VPNs, or privacy tools can block the connections Open Doors needs for calls.

Step 4Grant Microphone Permissions

Verify that Open Doors has permission to access your microphone. In your browser settings, check site permissions and ensure microphone access is allowed for the Open Doors domain.

Step 5Try Incognito or Private Mode

Open Open Doors in an incognito or private browsing window. This disables all extensions by default and can help identify if an extension is causing the issue.

Recommended Browser

Google Chrome typically provides the best performance for Open Doors calls. If you're experiencing persistent issues, try switching to Chrome as your primary browser for calling.

Test Your Audio Hardware

Hardware issues with your microphone, speakers, or headset can significantly impact call quality. Testing and properly configuring your audio devices ensures clear communication.

Step 1Test Your Microphone

Use your computer's sound settings or an online microphone test to verify your microphone is working. Speak into the microphone and confirm that audio levels respond to your voice.

Step 2Select the Correct Input Device

In your computer's sound settings, ensure the correct microphone is selected as the default input device. If you have multiple microphones connected, verify you're using the intended device.

Step 3Adjust Input Volume

Set your microphone input volume to an appropriate level, typically 70-80%. Volume that's too high can cause distortion, while too low may make you inaudible to callers.

Step 4Check Speaker/Headset Connections

Ensure all cables are securely connected. For USB devices, try a different USB port. For Bluetooth devices, verify they're properly paired and have sufficient battery charge.

Step 5Update Audio Drivers

Check your computer manufacturer's website for the latest audio driver updates. Outdated drivers can cause compatibility issues and degrade audio quality.

Hardware Recommendation

For the best call quality, use a dedicated USB headset rather than built-in computer microphones and speakers. Headsets reduce echo and background noise while providing clearer audio capture.

Quick TipStill Having Issues?If basic troubleshooting doesn't resolve the problem, the issue may be related to network configuration or advanced settings. Continue to the next sections for more detailed solutions.5

Configure Network Settings

Network configuration can have a significant impact on call quality. Firewalls, routers, and Quality of Service settings may need adjustment to prioritize voice traffic.

Factor 1Whitelist Required Ports

Open Doors requires certain ports to be open for voice traffic. Ensure your firewall allows UDP traffic on ports 3478-3481 and TCP traffic on ports 5060-5061. Contact your IT administrator if you need assistance configuring firewall rules.

Factor 2Enable Quality of Service (QoS)

QoS settings on your router prioritize voice traffic over other types of data. Access your router's admin panel and enable QoS for VoIP or real-time communications to ensure calls receive sufficient bandwidth.

Factor 3Disable VPN When Making Calls

VPNs can introduce latency and reduce call quality. If you use a VPN for security, try temporarily disabling it during calls to see if performance improves. If calls must be made over VPN, choose a server location close to your physical location.

Factor 4Check for Network Interference

If using WiFi, interference from other wireless devices can degrade performance. Move closer to your router, switch to a less congested WiFi channel (such as 5GHz instead of 2.4GHz), or reduce the number of devices connected to your network.

Note

Network configuration changes may require administrative access or assistance from your IT department. Document the original settings before making changes so you can revert if needed.

Advanced Troubleshooting

If standard troubleshooting steps haven't resolved the issue, these advanced techniques can help identify and fix persistent call quality problems.

Technique 1Monitor CPU and Memory Usage

Open your computer's Task Manager (Windows) or Activity Monitor (Mac) during a call. If CPU or memory usage exceeds 80%, close unnecessary applications. High resource usage can cause audio processing delays and dropped packets.

Technique 2Test on a Different Device

Try making a call from a different computer, tablet, or mobile device on the same network. If the issue persists across devices, the problem is likely network-related. If it only occurs on one device, focus on that device's settings and hardware.

Technique 3Test on a Different Network

Connect to a different internet network (such as a mobile hotspot) and make a test call. If quality improves, your primary network configuration is the likely cause. Work with your internet service provider or IT team to resolve network issues.

Technique 4Analyze Call Logs

Review call logs in Open Doors for patterns. Note if quality issues occur at specific times of day, with certain contacts, or after particular actions. This information helps identify whether the problem is environmental, network-related, or tied to specific configurations.

Technique 5Reset Open Doors Settings

In Open Doors' phone settings, reset your audio device selections and re-grant microphone permissions. Sometimes corrupted settings can cause persistent issues that only a reset will fix.

Success Indicator

Call quality is considered good when both parties can hear each other clearly with no delays, static, or interruptions. If you can have a natural conversation without repeating yourself or asking the other person to repeat what they said, your settings are optimized.
