Calls and conferences
Applies to: SimpleTwo 0.9.x · Checked: 20.09.2026
A call starts where the conversation is: from a chat, from a person's card or from a meeting. There is no separate app for calls.
One to one
Press the call button in a conversation. The other person gets an incoming call — with sound and on the lock screen, like an ordinary phone call. They can answer with voice or with video.
During the call:
| Control | What it does |
|---|---|
| Microphone, Camera | turn off and back on |
| Screen | share the screen or a single window |
| Audio | choose the speaker, a headset or headphones |
| Hold | pause: the other side sees "On hold" and audio stops in both directions |
| Transfer | hand the conversation to somebody else |
| Invite | bring in a third person — the call becomes a group call |
The back gesture minimises the call rather than ending it: the conversation continues while you walk around other screens.
In a secret chat media goes between the devices, bypassing the server. There is no room to enter, which is why no link into such a call can be made. If the other side's keys are not the expected ones, the call is refused: "keys did not match".
Inviting a third person
Invite shows who can be brought in and — this matters — what the invitation gives them:
- a member of this conversation simply hears the call;
- somebody from the directory is first added to the conversation or the meeting, otherwise they cannot be let in, and that outlives the call: they stay a member and see the messages.
The app says so at the moment of choosing, so that "let me pull a colleague in for five minutes" does not turn into silently adding them to a closed conversation.
A link into a call in progress
Conference link turns the conversation into a conference: anyone holding the link can enter. Useful when somebody without an account is needed quickly.
- The link lives while this call lasts; if nobody enters, it closes after 15 minutes.
- A guest arriving by link waits in the lobby until somebody lets them in.
- They get the call and nothing else: no messages, no history, no member list.
- The link can be closed at any moment with Close link.
For external participants you need to invite in advance, a meeting with a lobby fits better — it has a time, an invitation and a calendar entry.
Conference: presenter and floor
Large conversations use floor mode: only the speakers are heard, everybody else listens.
- Raise hand — ask to speak; the host sees the raised hands.
- Give the floor — the host grants the right to speak; Return to the floor takes it back.
- Mute switches a participant's microphone off; Ask to mute is the polite version, for when the person can do it themselves.
The right to speak is taken back by the server, not by the other person's app, so "it stayed on" does not happen here.
Recording
The host can start recording — everybody sees a RECORDING badge. The finished recording goes into the organisation's storage; where exactly, and who has access, is the administrator's decision.
A meeting created with a transcript requested is recorded automatically from the moment the first participant enters — even if the organiser never came.
0.9.x records the meeting; turning that recording into readable text is the next stage.
Calling a phone number
If the organisation has telephony, you can call an ordinary number from the app, and join a conference by phone when the internet is poor.
Dial the number the way you always do: converting it to international form is not your job — the server does that, using your site's country. That is why the same short number reaches the right place for colleagues in different countries.
Calling 112 or another emergency service from the app is refused — use a mobile phone. This is first-version behaviour and the refusal is deliberate: silently routing such a call "somewhere" is worse than an honest no.
When something goes wrong
| What you see | What it means |
|---|---|
| "Could not connect" | media did not get through — usually the network; try another one, or Wi-Fi instead of mobile |
| "Connection lost, reconnecting…" | the app is reconnecting itself; wait a few seconds |
| "The coordinator did not grant access to the call" | you have no right to this call: ask your administrator |
| "Could not reach the call server" | the call server is unavailable — a question for the administrator, not for you |
| "Waiting: the organiser has not let you in yet" | you are in the lobby |
Reporting a bad call
After a call the app shows its summary — who, how long — and closes it by itself in a few seconds (8 on a phone, 5 on a Mac). If the call was bad — the sound dropped, the connection broke, something did not work — press Report a problem with the call on that screen (iOS, Android, macOS). The report goes at once, with one tap and no form: support receives the call's number, the connection quality the app measured and the app version — the caption under the button says so. The button turns into "Sent, thank you" and the screen closes in three seconds.
The report reaches support like any problem report: you are answered in your chat with the support bot when an issue is filed for it. Several people reporting the same call make one issue. To describe it in more detail, write to the support bot or use "Report a problem" in Settings.
