Why is my VoIP call quality poor or choppy?
In the modern business landscape, clear communication is the bedrock of professional relationships. However, few things are as frustrating as a VoIP (Voice over Internet Protocol) call that sounds like a robot underwater or cuts out at a critical moment. If your business is plagued by “choppy” audio or dropped calls, you aren’t alone—but you also don’t have to settle for it.
At Buracom, we specialize in providing crystal-clear communication solutions. In this comprehensive guide, we will break down exactly why your VoIP quality might be suffering and provide a step-by-step roadmap to fixing it.
1. Understanding the “Big Three” of VoIP Issues
To fix poor call quality, we must first understand the technical culprits. Unlike traditional landlines, VoIP breaks your voice into small “packets” of data. If these packets don’t arrive on time or in order, the call fails.
A. Latency (The Delay)
Latency is the time it takes for a data packet to travel from your mouth to the listener’s ear. High latency results in that awkward “talk-over” effect where both parties speak at once because of the delay.
- Ideal Latency: Under $150ms$.
- The Buracom Standard: We optimize routing to ensure your packets take the shortest path possible.
B. Jitter (The Choppiness)
Jitter occurs when data packets arrive at irregular intervals. Imagine a line of cars on a highway; if they arrive one by one, traffic flows. If they arrive in a sudden cluster, it causes a “choppy” sound.
- Ideal Jitter: Below $30ms$.
C. Packet Loss (The Gaps)
Packet loss is exactly what it sounds like—some of the data simply disappears. This leads to missing words, robotic voices, or the call dropping entirely.
- Ideal Packet Loss: Less than $1\%$.
2. Common Causes of Poor VoIP Quality
Why are these technical issues happening in your office? Usually, it comes down to one of these four areas:
Insufficient Bandwidth
Every VoIP call requires a specific amount of “space” on your internet connection. If your team is running large file backups, streaming 4K video, or hosting high-def webinars on the same connection as your phones, the voice quality will suffer.
Outdated Hardware
Your router is the “traffic cop” of your office. If you are using a consumer-grade router for a business-grade workload, it likely lacks the processing power to handle real-time voice data efficiently.
Interference from Wi-Fi
While Wi-Fi is convenient, it is the enemy of VoIP. Walls, microwaves, and other electronic devices can interfere with the signal, causing the “jitter” mentioned above.
SIP ALG Settings
Many routers have a setting called SIP ALG (Session Initiation Protocol Application Layer Gateway). While it was designed to help VoIP, it often does the opposite—corrupting data packets and causing “one-way audio” where you can hear the client, but they can’t hear you.
3. How to Fix Your VoIP Quality: A Step-by-Step Guide
Step 1: Prioritize Voice Traffic (QoS)
This is the most effective fix. Quality of Service (QoS) is a router setting that tells your network: “Voice calls are more important than YouTube or emails.” When QoS is enabled, your router will always let voice packets go to the front of the line.
Step 2: Switch to a Wired Connection
If you are using a softphone on a laptop or a desk phone, plug it directly into the wall via an Ethernet cable (Cat6 or higher). This eliminates the instability of Wi-Fi and provides a dedicated “lane” for your data.
Step 3: Upgrade to Business-Grade Hardware
If your business is growing, it’s time to retire the home-office router. Buracom recommends using enterprise-level switches and routers that are specifically designed for high-concurrency VoIP environments.
Step 4: Disable SIP ALG
Log into your router’s administrative panel and find the “Firewall” or “Advanced” settings. Look for SIP ALG and turn it OFF. This simple click often solves $90\%$ of connection issues.

The Buracom Difference
We don’t just “plug and play.” We perform a full Network Assessment to ensure your bandwidth, jitter, and latency meet our rigorous standards before we even go live. If your current provider is leaving you with “choppy” calls, it’s time to switch to a provider that values clarity as much as you do.
5. Proactive Monitoring: The Final Piece
The best way to fix a problem is to prevent it. Buracom uses advanced monitoring tools to track your Mean Opinion Score (MOS). The MOS is a rating from 1 to 5 that measures how humans perceive the call quality.
- Score 4.0 – 4.5: Excellent (The Buracom Goal)
- Below 3.5: Noticeable issues
By monitoring these metrics in real-time, we can often identify a network issue before your employees even notice a dip in quality.
Conclusion
Poor VoIP quality is not a “fact of life” in the digital age—it is a symptom of a misconfigured network. By addressing bandwidth bottlenecks, optimizing router settings like QoS, and moving away from unstable Wi-Fi, you can achieve the “landline-clear” audio your business deserves.
Ready to stop apologizing for your call quality? Let Buracom handle the technical heavy lifting. We’ll audit your network and provide a seamless, high-definition communication experience that lets you focus on what matters: your business.
