Run the test
- Open Connection quality from the account menu, or use the connection-test shortcut in SIP lines.
- Check the displayed network and current voice region.
- Choose Run test and keep the page open until all three rounds finish. Use Cancel if you need to stop.
- Read the results and any recommendation before starting another test.
The test makes short reachability and response-time checks from your current browser. It does not place a call, use your microphone, log in to your SIP line or charge your balance.
What a result does—and does not—show
A successful result means the checked services responded from this browser at that moment. It does not guarantee that a SIP device on another network can connect or that every call will have good audio. The test does not measure bandwidth, packet loss, jitter, Wi-Fi signal strength or real call audio quality.
Use a comparison to narrow the problem
If a check is slow or fails, run it again on another available network. If permitted by your network policy, compare with the VPN disabled. Change one thing at a time so you can identify the difference. A browser extension or company network policy can also affect access.
Still having calling problems?
Check microphone permission and the selected audio device separately. For Support, include the visible results, test time, voice region, network type and the calling symptom. A screenshot of results is useful; passwords and API keys are not needed.
