MORE THAN A SPEED TEST
Measure What Matters for Business Calls
Internet speed is only one part of call quality. VoIP also depends on the consistency and responsiveness of your connection.
Use our guide to understand what latency, jitter, packet loss and QoS results mean for business calls.
Download & Upload
Measure how quickly your connection receives and sends data. Upload performance is especially important when several employees are using business phones at the same time.
Latency & Jitter
Latency measures delay. Jitter measures how much that delay changes from moment to moment. Excessive values can contribute to delayed, robotic or choppy audio. Learn What is a good jitter score for VoIP? Learn What is acceptable latency for VoIP?
Connection Consistency
A fast connection can still perform poorly when the network is busy. Loaded latency helps show how responsive the connection remains under demand.
How to Get a More Accurate Result
Test the correct network
Use the same office Internet connection and network your business phones normally use.
Use a wired connection when possible
Wi-Fi interference can affect the result. A wired computer provides a clearer picture of the Internet connection itself.
Pause heavy Internet activity
Temporarily pause cloud backups, large downloads, video streaming and software updates.
Test more than once
Run the test at different times of day. Intermittent ISP congestion may not appear in a single test.
Important: This browser-based test is a useful screening tool, but it does not replace a complete network assessment or continuous VoIP monitoring. Learn how continuity planning goes beyond connection quality.
