Packet loss
Pieces of audio that never arrive. Even 1 or 2 percent is heard as clipped words and robotic voices.
Speed tests don't tell you how a phone call will sound. This one does: it sends real call-sized traffic over your connection, quiet and busy, and grades it the way the phone industry does.
We'll send call-sized packets back and forth with our network, exactly like a phone call would, on a quiet connection and then while it's busy.
The test sends about 30 seconds of traffic between your browser and our test server in Ohio. Your result is saved so you can share it; see our privacy policy.

A fast connection can still make terrible calls. Voice needs a steady stream of small packets, delivered on time, every time.
Pieces of audio that never arrive. Even 1 or 2 percent is heard as clipped words and robotic voices.
Audio that arrives unevenly. Phones have to wait for stragglers, which adds delay or drops them.
How long your voice takes to make the trip. Too much and people start talking over each other.
What happens to calls when someone downloads a file or joins a video meeting. It's the most common reason office calls turn choppy.
A speed test measures how much data your connection can move. A phone call needs very little bandwidth, but it needs every small packet to arrive quickly and on time. This test sends traffic shaped like a real call (50 small packets a second, each way) and measures what actually happens to it, first on a quiet connection and then while we keep it busy.
We use the E-model, the industry-standard way to predict call quality from packet loss, jitter, and delay, and report it as a call quality score from 1 to 5 (a mean opinion score, or MOS). Your grade reflects the worse of the quiet and busy results, because a business network is busy all day.
Not necessarily. Ordinary VoIP is at the mercy of your connection. AEGIS is designed for exactly the kind of networks this test flags: every AEGIS site runs on multiple connections at once, in both directions, and the most reliable audio wins. Hear the difference or talk to us about your results.
The test couldn't get call-style (UDP) traffic through your network, usually because of a strict firewall. Many VoIP services won't work at all on a network like that. It's fixable, and every AEGIS deployment includes the network setup your calls need.
We save your test measurements so the share link works, along with your IP address and browser type, which we use to keep the test from being abused. If you choose to send us your results, we also receive the contact details you enter. Details are in our privacy policy.
Send us your results, or let's talk about your locations and connections. We'll show you exactly what AEGIS would look like for you.
