====== Joining by telephone ======

You can also join a meeting with an **ordinary phone call** – for example when someone has no computer at hand or has trouble with browser audio. Telephone participation is **audio only** (no video, no sharing).

===== How it works =====

Telephone access is **not available for arbitrary rooms**. It works on a **fixed binding: phone number → a specific room**. Whoever dials the assigned number lands **directly in that room** – no code, no room name, the call connects straight through.

  * **The number is created on request.** Write to the administrator (see [[:en:app:ac:zoomterms|Terms of service and privacy]]) saying which room it is for; the administration sets up a phone number for it and gives it to you.
  * One number always leads to one specific room.
  * Pass the number to participants who will join by phone, together with the room link.

===== Steps for the caller =====

  - Dial the phone number that belongs to that room.
  - Once connected you are in the meeting – you hear the other participants and they hear you. In the Jitsi client you appear as a participant connected by phone.

===== Worth knowing =====

  * **The public-room PIN does not apply to phone calls.** If you join a PIN-protected room by phone, you enter no code – the call connects directly. (The PIN only guards browser entry.)
  * A **password set by a moderator** during the meeting, and the **lobby**, do not apply to phone participants the same way as to the browser – arrange it with the moderator in advance.
  * **Dial-out** (having the meeting call your number) **is not supported** – the call is always placed by the caller toward the service.
  * **Muting:** a moderator can mute a phone participant; they unmute themselves (with a key on some phones, otherwise by asking to be unmuted).
  * Audio quality is that of an ordinary phone call.

===== Troubleshooting =====

  * **Call connects but there is silence in one direction** – Hang up and call again; if it persists, report it to support with the time of the call.
  * **Cannot get through** – Check you are dialing the correct number in international format; try from a different network.
  * **I ended up in a different room than expected** – Check that your number is the one assigned to the correct room – one number = one room.
