How do you ensure call quality when using WiFi calling apps?

1 Optimize Network

The backbone of WiFi calling is your internet connection. To ensure call quality, it's crucial to have a stable and robust WiFi network. Start by checking your internet speed; you need a minimum of 1 Mbps for a clear voice call. Place your router in a central location, away from obstructions and other electronic devices that could cause interference. If your signal is weak in certain areas, consider using a WiFi extender to increase coverage throughout your space.

2 Update Regularly

Software updates are often released to improve performance and fix bugs. Ensure that your WiFi calling app and your device's operating system are up to date. Developers continuously refine their software to optimize call quality, so running the latest version can make a significant difference. Additionally, check for firmware updates for your router which can enhance its functionality and stability.

3 Manage Bandwidth

Bandwidth is like a highway for internet traffic; too many vehicles can lead to congestion. When using WiFi calling apps, ensure that other devices on the network aren't hogging bandwidth. Streaming video or downloading large files can significantly impact call quality. Prioritize your call by temporarily disabling heavy bandwidth-consuming activities on other devices or setting up Quality of Service (QoS) rules on your router to give voice calls priority.

4 Control Environment

Your physical environment can impact call quality as much as your network does. Echoes in large rooms, background noise, and even the device's position can affect how well you're heard. Use a headset with a noise-cancelling microphone to minimize ambient noise. If possible, take calls in a quiet, enclosed space to prevent echoes and ensure your voice is clear and audible.

5 Monitor Performance

Keeping an eye on your WiFi calling app's performance during calls can help preempt issues. Most apps have built-in indicators that show signal strength and call quality. If you notice a decline in performance, you might need to move closer to your WiFi router or disconnect other devices that could be interfering with your connection. Proactive monitoring allows you to address issues before they disrupt your call.

6 Troubleshoot Issues

Even with all precautions, issues may arise. If you experience poor call quality, start by rebooting your router and device to clear any temporary glitches. If problems persist, run a diagnostic test on your network to check for packet loss or high latency, which can cause choppy audio or delays. Contacting your internet service provider or the app's support team can also provide solutions tailored to your specific situation.
