Troubleshooting Bad Call Quality Issues

FAQ 1: Why is my call quality poor, and how can I fix it?

Answer: If your calls sound choppy or unclear, the issue may be poor internet connectivity. To improve it:

  1. Test your internet speed using a reliable speed test tool (e.g., speed.cloudflare.com).
  2. Ensure your connection has at least 50Mbps for both download and upload speeds, a jitter under 10ms, and a ping below 40ms. If your connection is below these standards, consider upgrading your plan or router.

How to Test:

1. Visit speed.cloudflare.com to check your connection speed.

2. If your results show poor performance, contact your internet provider for assistance or consider upgrading your equipment.

FAQ 2: What does 'high-jitter' mean, and how can I fix it?

Answer: Jitter refers to the variation in time between data packets arriving at their destination. High jitter can cause audio distortion, like crackling or choppy speech. To fix this:

  1. Ensure that your router is not overloaded with other tasks.
  2. If you're using Wi-Fi, switch to a wired connection for more stable performance.
  3. Check your router's settings and consider adjusting the Quality of Service (QoS) settings to prioritize VoIP traffic.

How to Use:

  1. Connect your device directly to the router using an Ethernet cable.
  2. If you're using Wi-Fi, ensure that you are close to the router and that there are minimal obstructions.

FAQ 3: What is 'high-packet-loss,' and how can I resolve it?

Answer: Packet loss occurs when data packets fail to reach their destination. It can cause poor call quality and even drop calls. To address packet loss:

  1. Test your network using test.8x8.vc to check for compatibility with VoIP.
  2. If packet loss is detected, check if other devices are consuming too much bandwidth and consider disconnecting them during important calls.
  3. Ensure that your router firmware is up to date, and consider using a higher-quality router if needed.

How to Test:

  1. Visit test.8x8.vc to see if your network is compatible with VoIP.
  2. If packet loss is detected, contact your internet provider for troubleshooting.

FAQ 4: What does 'high-rtt' mean, and how can I fix it?

Answer: High round-trip time (RTT) means there's a delay in sending and receiving data between you and the other party. To reduce RTT:

  1. Use a local server or closer data center if possible.
  2. Check for high network congestion or background applications that may be consuming bandwidth.
  3. Switch to a faster internet connection, if possible.

How to Fix:

  1. Visit a speed test site like speed.cloudflare.com to check your RTT.
  2. If RTT is high, contact your provider to check for network issues or consider a faster internet plan.

FAQ 5: How can I ensure my mobile app doesn't experience call quality issues?

Answer: If you're using a mobile app and experiencing poor call quality, the following steps can help:

  1. Check for 'high-jitter' or 'high-packet-loss' warnings within the app. These indicators will let you know what might be wrong.
  2. Move to a location with a stronger signal if you're on Wi-Fi or cellular data.
  3. Try using the app on a different network to see if the issue persists.

How to Use:

  1. Open your mobile app and check for any call quality warnings, such as "high-jitter" or "high-packet-loss."
  2. If warnings appear, move closer to the router or switch to a more stable network.
