Each VoIP line uses approximately 100 Kbps of upload and download. A 10-user office needs at least 1–2 Mbps dedicated to voice, well within most business internet plans.

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.
