For MSPs & IT Providers
Send this to your client before blaming the carrier
A browser-based VoIP quality test your clients can run themselves. No install, no account, no mic permissions -- just a link and a shareable report.

Methodology & metrics
The workflow
1. Send the link
Client reports choppy audio or dropped calls? Send them voiptest.com/tools/voip-test/run. It runs in any modern browser -- nothing to install, no mic permissions, no account to create. Even non-technical users can run it in under two minutes.
2. They run the test
The test sends real WebRTC media traffic from their desk -- the same codecs, packet sizes, and timing as an actual call. It measures the path your client's calls actually take, not a generic speed test.
3. You get the report
Every test produces a shareable report link with MOS (ITU-T G.107), packet loss, jitter, and latency. Your client sends you the link; you read the numbers before anyone opens a ticket with the carrier.
4. Escalate with evidence
If the numbers point at the network, attach the report to the carrier ticket. If they don't, you just saved a truck roll and a week of finger-pointing. Either way, the conversation starts from data.
Why MSPs use it
End the blame game
Carrier says it's the LAN. ISP says it's the provider. An independent test from the client's own machine gives you a neutral data point nobody's support script can wave away.
Qualify before you deploy
Rolling out hosted voice for a new client? Have them run the test from the desks that will make calls -- before you sign off on the network. Run up to four simultaneous calls and see whether the connection actually holds them, rather than dividing bandwidth by a codec bitrate and hoping.
Zero client friction
No agent to deploy, no software to license, no credentials to manage. A link in an email or ticket reply is the entire rollout.
Hear what they hear
The audio reconstruction demo plays back what the test audio sounded like after crossing the network -- useful when a client insists calls are fine, or insists they're not.
Frequently asked questions
Does my client need to install anything or create an account?+
No. The basic test is free, anonymous, and runs entirely in the browser. No downloads, no extensions, no microphone permissions, and no sign-up. You send a link; they click Run.
How do I get the results from my client?+
Every completed test generates a shareable report link. Your client copies the link and sends it to you -- in a ticket reply, email, or chat. The report includes MOS, jitter, packet loss, latency, and methodology notes.
Is this just a speed test?+
No. Speed tests measure bulk throughput, which says almost nothing about voice quality. This test sends real RTP-path media traffic with voice-sized packets at voice timing, and measures jitter, loss, and latency -- the metrics that actually determine whether calls sound good.
Can I use the results in a carrier or ISP dispute?+
That's the point. Reports use industry-standard metrics (ITU-T G.107 MOS scoring) and include methodology notes, so the evidence holds up when you escalate to a provider or ISP.
What does it cost?+
The basic test is free with no account required, for you and for your clients. Premium features -- extended durations, multi-path concurrent load testing, test history, scheduled recurring tests, and PDF export -- are on the roadmap under a paid tier.
