Dealing with Poor Call Quality? JustCall Can Help You Troubleshoot.

Have you ever been in the middle of a crucial sales call, only to have your voice turn into a robotic mess? It’s enough to make you feel like Darth Vader himself is interrupting your pitch. As we’ve discussed previously, a single bad call can leave a lasting negative impression.

Here’s a statistic to chew on: While 97% of calls going through JustCall happen seamlessly, around 3% of calls are impacted by network conditions each month. Now, before you hit the panic button, here’s the silver lining – a whopping 80% of those call quality woes can be traced back to a single foe: jitter.

So… what’s the jazz with jitter?

Jitter, for those unfamiliar with the villainous term, is the Darth Vader of call quality – that pesky culprit that wreaks havoc, turning your voice into a robotic mess. Technically speaking, it’s the statistical variance in transmission delay, i.e., voice packets not arriving in calls at the same time. Some of the common issues of jitter include:

  • Poor network connection: When your network connection is weak or unstable, data packets can arrive at their destination at different times, causing jitter. This can happen due to factors such as interference, signal attenuation (loss of signal strength in networking cables or connections), or a long distance between the sender and receiver.
  • Network congestion: High network traffic can lead to congestion, causing delays in packet delivery and increasing jitter. This typically occurs during peak usage hours or in environments with limited bandwidth, such as shared networks or public Wi-Fi hotspots.
  • Hardware issue: Faulty or outdated networking equipment, such as routers or modems, can contribute to jitter. Issues like outdated firmware, hardware malfunctions, or improper configurations can disrupt the smooth transmission of data packets, leading to jittery audio.

So, now that you know what jitter is and how it can mess with your calls, let’s zoom out and see how it fits into the whole picture, especially with the 80-20 rule.

The 80:20 rule

We’re all familiar with the 80-20 rule: 80% of negative impact stems from just 20% of recurring issues. This principle applies to the call quality of VOIP calls as well. Consider this: out of 1000 calls made on JustCall, if 10 are affected by poor quality, eight of those suffer from Jitter (resulting in robotic voices), while the remaining two are influenced by other network factors like latency and packet loss. So, what can you do about it? You’re about to find out.

How JustCall helps users identify call quality issues

The first step to solving a problem is acknowledging it exists. That felt therapeutic for a moment, right?

The good news is that JustCall equips its customers with all the tools they need to identify call quality issues:

1. Slow internet connection mode

For situations with limited bandwidth, you can switch to this mode to optimize call quality without sacrificing clarity.

2. Real-time network alerts

Imagine having a trusty sidekick whispering warnings during your calls, discreetly alerting you to any potential network issues. That’s the magic of JustCall’s real-time network alerts! These helpful notifications pop up during your call, highlighting any potential problems so you can take action and ensure a smooth conversation.

3. Diving deeper into the alerts

You can click on ‘Troubleshoot’ to reveal specific network issues like high latency, jitter, packet loss, or a low MOS score. You can also access relevant troubleshooting steps for each issue through the dropdown menu.

In case of a significant network drop, JustCall will show a ‘Reconnecting’ notification, signaling users to consider switching to a stable connection. JustCall attempts to restore the connection; if unsuccessful within a minute, the call drops, prompting users to troubleshoot and make a new call.

JustCall doesn’t just identify problems – we empower you to fix them! Keep reading to find out how.

What steps can you take as a user to troubleshoot call quality issues proactively

1. Choppy audio or voice breakup:

  • Check your internet connection speed using a speed test tool.
  • Limit the number of devices using the network during calls.
  • Consider using a wired connection instead of Wi-Fi for more stability.

2. Echo or audio feedback:

  • Ensure you’re using a headset with noise-cancellation features.
  • Adjust your microphone and speaker volumes to avoid feedback loops.
  • Close any unnecessary applications that might be causing audio interference.

3. Dropped calls:

  • Restart your router and modem to refresh the internet connection.
  • Optimize your network by minimizing the use of bandwidth-intensive activities during calls.

4. Audio delays (Lag):

  • Choose a server or data center closer to your geographical location, under JustCall settings.
  • Close background applications that might be consuming network resources.

5. VoIP Quality of Service (QoS) configuration:

  • Want to squeeze even more performance out of your JustCall experience? You can prioritize VoIP traffic to ensure your voice data gets sent first, and minimize delays by using a smaller buffer size on your router (check your router’s manual if needed). Opening specific ports (10,000-60,000) and whitelisting JustCall’s global IP address (168.86.128.0/18) can further enhance uninterrupted communication.
  • Regularly updating your router and device software keeps things running smoothly and eliminates bugs that might affect call quality. You can even experiment with different audio codecs on your device to find the perfect balance for your setup.
