Make sure you can make and receive calls in your browser. Run a call quality test in your telephony settings.
Connect your headphones before you start the test. You won’t hear the test audio without headphones or speakers. You also need a microphone to complete the test.
Ad blockers or antivirus software may block calls. Add your Bitrix24 account address and the test page to the exception list.
Take the test
To check your connection quality, open:
https://echo.voximplant.com/iframe.html
Then click Get started.
The test checks:
- Browser version
- SDK load
- Media access
- Authorization
- Test call
- Connection quality (audio clarity and packet loss)
When the test finishes, you’ll see the results. If there’s an issue, the page will show how to fix it.
If everything is working, the test will pass successfully.

Browsers usually ask for microphone access in a pop-up. If you don’t see it and the test says no microphone is found, allow access in your browser settings.
