Before you open the room
Have two devices, two email addresses and an internet connection ready. A microphone is required on each device. Headphones are useful when the people or devices are near each other, because they help prevent sound from one speaker returning through another microphone.
Decide what you want to learn: whether a changed meeting point is understood, whether the microphone is clear, or whether using the talk control feels practical on your phone. Pick one question first.
Verify and join
Start at the free-trial page and request your private email link. Verification links are single use and expire after fifteen minutes. Open your room and share the invitation with your colleague, who verifies their own email.
Allow microphone access when your browser asks. If you cannot hear one another, check the selected microphone, speaker volume and browser permissions before starting over. Refreshing does not reset the trial allowance.
Run one short exchange
The public trial allows two people and up to ten minutes per email every twenty-four hours. Say the destination or person first, then the action. Release the talk control to listen. Ask the other person to repeat the important part in their own words.
Switch roles. Try a normal speaking volume and the headset you actually intend to use. A test in a quiet office is a first step; repeat the relevant checks on location before making operational decisions.
Save what you want to keep
Trial recordings stay in browser memory. Replay or download them before refreshing or closing the page. Unsaved audio is cleared when you leave. Tell everyone in the room that the session is being recorded.
Finish by writing down what worked and what needs another test. If you need team channels, shared history or administration, those belong to the separate workspace preview and require workspace access.
Check the input and the output separately
A microphone permission is not the same as a working input. Check that the browser is allowed to use the intended microphone, then confirm the speaker or headset is audible. If two devices are close together, use headphones or separate their locations to reduce echo. Change one setting at a time so the effect is clear.
If the other person cannot hear you, check the talking state and selected input first. If you cannot hear them, check your output volume and their input. An interrupted connection is a different issue from a muted speaker. Keep your observations specific and use the existing retry or permission controls before creating another room.
Observe the behavior that matters at work
Test the pair of devices you actually intend to use, including their normal browser and headset. A desktop-to-tablet result does not certify a different phone or background mode. Observe orientation changes, screen locking and switching away from the browser. Record what happens instead of assuming continuous background operation.
Repeat the exchange at the relevant location and under normal noise and network conditions. A loading bay, a basement and a parked vehicle can have very different connectivity. Use devices only where workplace rules permit. This checklist supports an evaluation; it does not replace your organization’s operating or emergency procedures.
Turn observations into the next test
Write down what was understood, what had to be repeated and whether either participant changed a setting. Choose one adjustment: a different microphone position, a clearer entrance name or a better test location. Repeat the same short exchange. A second controlled observation is more useful than changing everything and guessing why it improved.
