Audio Quality VoIP: Fix Crackles, Delays, and Choppy Calls
When your audio quality VoIP, the clarity and reliability of voice transmitted over internet-based phone systems. Also known as VoIP voice quality, it determines whether a call feels natural or like you're talking through a tin can. Poor audio isn't just annoying—it kills productivity, frustrates customers, and makes remote teams feel disconnected. You don't need expensive gear to fix it. Most issues come down to network settings, codec choices, and how your device handles voice packets.
The real problem? Many people think better internet speed alone solves audio quality VoIP issues. It doesn't. A 100 Mbps connection won't help if your router drops voice packets or your codec uses 30ms intervals when 20ms is the sweet spot. MOS, a standard score from 1 to 5 that rates voice clarity in VoIP systems and PESQ, an objective measurement tool used by engineers to predict how humans perceive call quality tell you exactly where your call is failing—whether it's jitter, latency, or packet loss. And codec packetization, how often voice data is bundled into packets before sending—10ms, 20ms, or 30ms—can make or break your call. Most businesses stick with 20ms because it balances quality and bandwidth. Go too low, and you strain your network. Go too high, and voices sound robotic or delayed.
It’s not just about the tech. Your headset, Wi-Fi signal, and even background noise matter. A DECT headset gives stable audio in an office, while Bluetooth might drop calls when you walk away from your laptop. If your calls sound fine on Zoom but terrible on your VoIP app, the issue isn’t your internet—it’s how your phone system handles audio processing. And if you’re using an old analog phone with an ATA adapter, you might be fighting echo or low volume because the device isn’t configured right.
Below, you’ll find real fixes—not theory. From tuning packet intervals to stopping SIP brute-force attacks that degrade performance, these posts give you the exact steps to make your calls clear, consistent, and professional. No fluff. No jargon. Just what works.
