Understanding Your Results

What Each Number Actually Means

Speed isn't the only thing that matters for VoIP. Here's what to look at — and why.

⬇️
Download Speed
How fast data comes to your device. For VoIP, 10 Mbps or more is plenty for most offices. This is rarely the bottleneck.
⬆️
Upload Speed
How fast data leaves your network. Upload is critical for VoIP — your voice travels outbound. Aim for at least 5 Mbps for a small team.
⏱️
Ping / Latency
The round-trip delay between your device and the server. Under 70ms is ideal. High latency causes noticeable delay in conversations — the "over and out" effect.
📊
Jitter
How consistent your connection is. Jitter is the #1 cause of choppy or robotic-sounding calls. Even a fast connection with high jitter will sound terrible on VoIP. Keep it under 20ms.
