Having VoIP Call Issues? Check These 5 Things for Clearer Connections.

Every deal, every strategy session, every customer conversation depends on a strong connection—literally. If your VoIP calls are cutting out or sounding garbled, it’s not just annoying—it’s bad for business. “Can you hear me now?” isn’t a question you should be asking in the middle of an important call. Clear communication starts with a fast, stable Internet connection that keeps up with the way you work. Whether you’re leading a virtual meeting, checking in with a client, or closing a major deal, your VoIP service should be the least of your worries.

The good news? Most VoIP issues aren’t actually VoIP issues at all—they’re network issues. And the better news? You can fix them. A few simple optimizations can make a big difference in call quality, keeping your conversations clear and frustration-free. Here’s where to start:

1. Check Your Bandwidth (Because Not All Internet is Created Equal)

The Issue: VoIP might need more bandwidth than you think, (about 100 kbps per call). If your network is overloaded with video calls, cloud apps, and random downloads, your voice traffic might be getting squeezed out.

The Fix:

• How many simultaneous calls are happening? Multiply that by 100 kbps and make sure your Internet package can handle the load.
• Check what else is eating up your bandwidth. A single HD video stream can take 20-100 times more bandwidth than a VoIP call.

How SupraNet Helps: We’ll analyze your bandwidth needs and make sure your Internet is more than capable of handling your business’s call volume.

2. Prioritize Your VoIP Traffic (Because Your Calls Shouldn’t Wait in Line)

The Issue: If your VoIP calls have delays, lag, or choppy audio, your router might be treating voice traffic the same way it treats everything else—meaning it gets stuck behind large file downloads and cat videos.

The Fix:

• Turn on Quality of Service (QoS) in your router settings. This gives VoIP calls VIP treatment so they always go through smoothly.
• Segment your network. A dedicated VLAN (Virtual Local Area Network) for VoIP keeps call data separate from everything else.

How SupraNet Helps: We’ll configure QoS for you so your VoIP calls always come first. No more battling your own network for a clear conversation.

3. Get Wired (Wi-Fi is Convenient, but Ethernet is King)

The Issue: Wi-Fi is great for browsing the web, but for real-time communication like VoIP, it can be inconsistent. If your calls keep dropping or the audio randomly cuts in and out, your wireless connection might be to blame.

The Fix:

• Use a wired Ethernet connection for your VoIP phones whenever possible—it’s faster and more reliable than Wi-Fi.
• If you must use Wi-Fi, make sure your router is in a central location, and you’re not dealing with interference from walls, appliances, or even that suspiciously thick conference table.

How SupraNet Helps: We optimize your network setup for maximum VoIP reliability—wired or wireless.

4. Watch Out for Latency & Jitter (Because No One Likes Talking Over Each Other)

The Issue: Ever had a conversation where there’s a weird delay between when you talk and when the other person hears you? Or when voices sound robotic or distorted? That’s latency and jitter, and it happens when data packets aren’t moving smoothly across the Internet.

The Fix:

• Check your Internet connection speed—a good VoIP experience requires low latency (under 150ms) and minimal jitter (under 30ms).
• Use a high-quality router designed for business VoIP. Some consumer-grade routers just can’t keep up.
• Choose a business-class ISP that prioritizes low-latency, high-quality connections (hey, we know a great one).

5. Work With the Right VoIP Provider (Because Not All VoIP is Created Equal)

The Issue: Sometimes, it’s not your Internet—it’s the VoIP provider itself. Some providers compress voice data too much, leading to lower call quality, while others just don’t have the right infrastructure to handle high call volumes.

The Fix:

• Make sure your VoIP provider supports HD voice for the clearest audio possible.
• Choose a provider that prioritizes uptime and reliability.
