Is your Internet ready for VoIP?
This test measures from your browser what matters for call quality: latency, jitter, packet loss, speeds and UDP traversal. Run it from where you'll use your phones.
How to read the results
| Metric | Excellent | Acceptable | Why it matters |
|---|---|---|---|
| Latency | under 120 ms | under 250 ms | Beyond that, people talk over each other. |
| Jitter | under 20 ms | under 40 ms | High jitter makes the voice choppy. |
| Packet loss | under 1% | under 3% | Lost packets mean missing words. |
| Bandwidth | about 100 kb/s per call, each way | A 5 Mb/s upload easily handles more than 20 calls. | |
The test measures an HTTP round trip to our server in Canada: actual call latency is usually a little lower. The UDP test uses a public STUN server.
Improve call quality
- Connect desk phones and the home adapter to the router by cable rather than Wi-Fi when possible.
- Avoid very large uploads (cloud backups) during calling hours, or limit them in the router.
- With Starlink: keep the dish free of obstructions; typical latency is well suited to voice.
- Weak result? Call us: we'll look at your situation for free before you order.
Frequently asked questions
What Internet speed do I need for VoIP?
About 100 kb/s per simultaneous call, each way. For 5 employees on the phone at once, 1 Mb/s upload is enough; stability (latency, jitter) matters more than speed.
Does VoIP work over cellular Internet or Starlink?
Yes, in the vast majority of cases. Run the test from that connection to confirm.
