Is your network ready for TSN Phone?
Test your internet connection’s latency, jitter, and reliability to identify potential issues that could affect voice quality and calling performance.
TSN Phone readiness test
Check whether your current internet connection and browser are suitable for internet-based phone calls. Our diagnostic tool evaluates connection responsiveness, consistency, and browser capabilities to help identify potential call quality issues. No installation or login required.
Phone connection readiness
Check your current internet connection for conditions that may affect TSN Phone call quality.
Preparing connection diagnostics…
The test performs a series of small HTTPS requests to measure connection timing and reliability. No phone-system credentials or installation are required.
Connection test results
These measurements represent your browser’s connection to a public HTTPS test service. They may help identify conditions affecting call quality, but they do not directly test your TSN Phone server or voice traffic.
Please note: This test provides an estimated assessment of your connection’s suitability for TSN Phone. Results vary with network conditions, device performance, and routing. This test does not establish a live phone call or directly measure SIP/RTP voice traffic. Failed HTTPS requests should not be interpreted as VoIP packet loss.
Understand your results
Latency & Call Responsiveness
Latency measures how quickly information travels across a network. High latency can cause noticeable delays during conversations, making calls feel less natural.
Jitter & Connection Stability
Jitter measures variations in network response times. Excessive jitter can cause choppy audio, inconsistent sound quality, and interruptions during calls.
Network Reliability & Browser Compatibility
Network interruptions and browser limitations can affect internet calling. This test checks request reliability and supported browser features to identify potential issues.
