Telegram Conference Calls: Encrypted Calls Without a Group

A Telegram conference call is a voice or video call with several people that does not live inside a group chat. You start it from the Calls tab, from a call link, or by adding someone to an ordinary one-to-one call, and the call is end-to-end encrypted. Everyone can confirm that encryption by comparing a short row of emoji on their screens.

This guide explains what the feature is, how to start and join one on each platform, how the encryption check works and what it does not cover, and what to do when a call will not connect.

What a conference call is, and what it is not

Telegram has had several kinds of calls for years, and the names overlap. It helps to separate them before you start.

• One-to-one calls. A voice or video call between two people. These have been end-to-end encrypted since they launched, with an emoji key you can compare.
• Video chats and voice chats in a group or channel. These belong to a group or channel. Anyone in the group can join while it runs, and a channel can use the same feature as a live stream for a large audience. They are built for communities, not for private meetings. Our guide to voice chats and live streams covers them in depth.
• Conference calls. A group call that is not attached to any group or channel. Telegram's developer documentation describes it exactly that way: a group call with no chat behind it, joined through an invite link or by being added. These calls are end-to-end encrypted.

The difference matters for two reasons. First, you no longer need to create a throwaway group just to talk to four people at once. Second, a group's video chat is not the same as an encrypted conference call, so if privacy is the reason you are calling, you want the conference call.

Why Telegram built it this way

Before conference calls, a private group meeting meant making a group, adding everyone, starting a video chat, and then leaving the empty group behind. That group kept a member list and a chat history that nobody needed. A conference call carries none of that. The call exists while people are in it, and the link is the only thing you hand out.

The second reason is encryption. Group video chats are protected in transit like normal cloud chats, but they are not end-to-end encrypted. Conference calls were designed from the start so that only the people in the call hold the keys.

Before you start

A few checks save most of the trouble people run into.

1. Update Telegram on every device you plan to use. Conference calls are a newer feature. An older app may not show the option at all, or may not be able to join a call someone else created.
2. Ask the other people to update too. If one person is on an old version, the app may not offer to add them, or they may see the link but fail to join.
3. Check microphone and camera permissions. On a phone, the operating system asks the first time Telegram wants the microphone or camera. If you refused once, Telegram cannot ask again, and you have to allow it in the phone's own settings.
4. Prefer the app over a browser. Telegram's own interface text notes that encrypted group calls are not supported in every browser, and asks people to open the call in a supported Telegram app instead.
5. Know who should be on the call. A call link works for anyone who has it. Decide in advance whether you will add people directly or share a link, and where that link will be posted.

How to start a conference call

There are three ways in. All of them lead to the same kind of call.

Start one from the Calls tab

This is the simplest path when you already know who should be on the call.

1. Open the Calls section of Telegram. On Android it is in the side menu; on iPhone it is a tab at the bottom if you have it enabled; on Desktop it is in the main menu.
2. Start a new call and choose several contacts instead of one.
3. Pick voice or video.
4. Telegram rings each person. Those who answer join the call; the others can join later through the call's link if you send it.

If you do not see the Calls tab on iPhone, it can be switched on in Telegram's settings. The exact location of that switch has moved between versions, so look in the general or appearance settings, or search the settings for "Calls".

Create a call link

A link is best when you are planning ahead or inviting people who are not in your contacts.

1. In the Calls section, choose the option to create a call link.
2. Telegram generates a link for a new call. You can copy it, share it in a chat, or show it as a QR code.
3. Send the link to the people who should join. Telegram's own announcement suggests this for scheduling calls in advance, since the link can be sent by email or another app as well.
4. When it is time, open the link yourself and join. Others join by opening the same link.

A link does not ring anyone. People have to open it at the agreed time, so put the time in the message that carries the link.

Turn a one-to-one call into a conference

You are already talking to one person and need a third.

1. During the call, look for the option to add a person or participant.
2. Choose the contact or contacts to add.
3. Telegram moves the call to a conference. Telegram's developer documentation describes this as the app creating a new conference call and then ending the one-to-one call, with the other person joining the new one automatically.

You may notice a brief pause while this happens. That is the switch from one call type to the other, not a dropped connection. The add option only appears when the other person's app supports conference calls, so if you cannot find it, an outdated app on either side is the usual reason.

Platform differences

The feature is the same everywhere, but where you find it and how it behaves differs.

Android

The Calls list sits in the side menu. Android asks for microphone and camera access per app, and some phone makers add their own battery restrictions that can cut a call when the screen turns off. If calls drop when you lock the phone, allow Telegram to run in the background in the phone's battery settings.

iPhone and iPad

Telegram calls use Apple's calling interface, so an incoming conference call can appear on the lock screen like a normal phone call. If you never see incoming calls, check that Telegram is allowed to send notifications and that Focus modes are not silencing it.

Telegram Desktop

Desktop can start and join calls, and it is the most comfortable place for a long video meeting or for sharing your screen. Check the audio input and output device in Telegram's call settings before the meeting. Many "nobody can hear me" problems on a computer are the wrong microphone being selected.

Web and browsers

Telegram's web versions handle many features, but encrypted group calls depend on what the browser supports. If the web version tells you the call is not supported, open the link in the Desktop or mobile app. Joining from the app also gives you more reliable access to the microphone and camera than a browser tab.

How to join a conference call

Joining is the same whichever way the call was created.

1. If someone adds you, your phone rings like a normal Telegram call. Answer it.
2. If someone sends you a link, tap it. Telegram shows a preview of the call and lets you join.
3. If someone shows you a QR code, scan it with your phone's camera or from within Telegram. It opens the same link.
4. Choose whether to join with your camera on or off, and whether your microphone starts muted, if the app asks.

Once inside, you can see who else is on the call. Check the list before you speak about anything private. A call that was created from a shared link can include people you did not expect if the link travelled further than intended.

The emoji check: how to prove the call is encrypted

End-to-end encryption means the keys that lock the call live only on the participants' devices. Telegram's servers carry the call but cannot decode it. The emoji are how you confirm that nobody slipped in between.

How to do the check

1. While the call is running, look for the row of emoji on the call screen. Telegram shows four emoji.
2. Ask one person to read their emoji out loud, in order.
3. Everyone compares with their own screen.
4. If every participant sees the same four emoji, the call's keys match and the call is secure.
5. If anyone sees different emoji, end the call and start a fresh one. Do not continue the conversation.

Why the emoji mean something

The emoji are a short, readable fingerprint of the key that encrypts the call. Each device computes them from the key it holds. If an attacker had placed themselves between participants, the devices would hold different keys and produce different emoji. Reading them aloud over the call works because a person's voice is hard to fake in real time.

When someone joins or leaves, the key changes and so can the emoji. That is expected. If you are checking during a long call, compare again after the participant list changes.

What sits behind the scenes

Telegram's developer documentation describes conference calls as using a blockchain-style shared log to manage the call's state, including who is in it and which keys are current. Each participant's app checks that log, so the participant list itself is something the devices agree on rather than something the server alone decides. You do not need to understand the details to use the feature. The practical meaning is that the list of people on screen is the list of people who can decode the call.

What encryption protects, and what it does not

Encryption is a strong guarantee about one thing: nobody outside the call, including Telegram, can listen to the content. It says nothing about the people inside the call.

It protects against:

• Someone intercepting the call on the network.
• The server operator decoding the audio or video.
• A participant being silently impersonated, provided you do the emoji check.

It does not protect against:

• A participant recording the call. Anyone in the call can record their screen or hold another device up to the speaker. Treat every call as something that could be kept.
• The link travelling. Anyone with a valid link can try to join. Encryption keeps outsiders out of the content, but someone who joins with the link becomes an insider.
• Metadata. The fact that a call happened, roughly when, and between which accounts is not hidden in the same way as the content.
• A compromised phone. If a device has malware or someone else has access to the account, encryption cannot help.

For a fuller picture of which parts of Telegram are encrypted end to end and which are not, read is Telegram end-to-end encrypted. If you want encrypted text as well, secret chats are the one-to-one option.

Conference call or group video chat: which to use

Both let several people talk at once. They suit different jobs.

Choose a conference call when:

• The meeting is private and you want end-to-end encryption.
• The people do not share a group, and you do not want to create one.
• It is a one-off: a family call, a client meeting, an interview.
• The number of people is small to medium. Telegram's announcement put the cap for adding people to an active call at 200 participants at the time; check inside the app if you need a precise current figure.

Choose a video chat in a group or channel when:

• The call belongs to a community that already exists.
• You want people to drop in and out of a call that is announced to the whole group.
• You need very large audiences or a live stream to a channel.
• You want features tied to the community, such as letting members raise their hand or giving speaking rights to some people.

A simple rule: if you would be annoyed that strangers can find the call, use a conference call. If the point is that the community can find it, use the group's video chat.

Managing a call while it runs

What you can do in a call depends on the app version, and some controls are limited to whoever started the call. These are the controls people look for most.

Muting and camera

Each person controls their own microphone and camera with the buttons at the bottom of the call screen. Muting yourself when you are not speaking reduces echo and background noise for everyone.

Adding more people

You can add more people during the call, either directly from your contacts or by sharing the call link again. Each person you add directly gets a ring.

Removing someone

If a person should not be there, the call's creator can usually remove them from the participant list. If the call came from a link that has spread too far, removing people one by one is a losing game. End the call and create a fresh one with a new link, then send it only to the right people.

Screen sharing

On Desktop and on recent mobile versions, you can share your screen or a single window during a call. Our guide to sharing your screen on Telegram covers how it works on each platform and what to close before you share.

Worked examples

These are illustrations of how people use the feature, not instructions you must copy.

Example: a family call across countries

Ana wants her parents and her brother on a weekly video call. They all have Telegram but no shared group. She opens the Calls section, picks the three contacts, and starts a video call. Everyone's phone rings. Her father's app is old and he cannot join, so she asks him to update and then sends him the call link. He joins two minutes later. At the start, Ana reads out the four emoji, everyone confirms, and the call goes on.

Example: a freelancer's client meeting

Tom has a call with a client and the client's designer. He creates a call link the day before and sends it in his chat with the client, together with the time. The client forwards it to the designer. At the meeting time, all three open the link. Tom notices a fourth name he does not recognise. He asks the client, who says it is a colleague. Tom keeps the call going but makes a mental note: forwarded links reach people you did not invite, so he says nothing confidential until he knows who everyone is.

Example: turning a quick call into a meeting

Sara is on a one-to-one call with a colleague when they realise they need the team lead. She taps the option to add a person and picks the lead. The call switches to a conference, there is a short pause, and the lead's phone rings. When the lead joins, the emoji on the screen change because the key changed. They compare the new emoji and carry on.

Running a meeting that goes smoothly

A conference call has no agenda, chat history or shared notes attached to it, because there is no group behind it. That is the point of the feature, but it means the organiser has to do a little more.

1. Put the context in the invitation. The message that carries the link should say the time, the time zone, the topic and roughly how long it will take. Nobody can scroll back through the call itself to find it.
2. Join a few minutes early. You can check your microphone and camera, and you are there to confirm who is who as people arrive.
3. Ask people to mute when they are not speaking. With several open microphones, one noisy room or one speakerphone without echo cancellation affects everyone.
4. Decide where notes and files go. Links, documents and decisions shared during the call need a home afterwards. A one-to-one chat, a small group or a shared document works; the call will not keep them.
5. End the call when you are done. Leaving it running means the link still leads somewhere.

If you find you run the same meeting with the same people every week, that is a sign a small group might suit you better after all: the group keeps the history, and you can still start an encrypted conference call from the Calls section whenever you need privacy.

Keeping call links under control

Links make conference calls easy and also make them leak. A few habits help.

• Send the link in a private chat, not in a public group or a channel post.
• Make a new link for each meeting rather than reusing one link for weeks. A link from last month's meeting may still be sitting in a dozen chats.
• Say who the link is for in the message that carries it, so people know not to forward it.
• Check the participant list at the start. Do not discuss anything private until everyone on screen is someone you expect.
• Be wary of call links from strangers. A link that promises a prize, a job interview or a crypto opportunity is a common opener for scams. Our guide to spotting Telegram scams lists the usual patterns. Nobody legitimate will ask you for your login code during a call.

Privacy settings that affect calls

Telegram lets you choose who can call you. That setting lives in the privacy and security section of the app's settings.

• If you limit calls to your contacts, people outside your contacts cannot ring you directly, including adding you to their conference call.
• They can still send you a call link in a chat if they can message you, and you decide whether to open it.
• For one-to-one calls, you can also choose whether calls are relayed through Telegram's servers instead of a direct peer-to-peer connection. Relaying hides your IP address from the other person, at some cost to quality on poor connections. Since a call you later expand into a conference starts as a one-to-one call, it is worth knowing where this setting is.

Our Telegram privacy settings checklist walks through these and the other settings worth reviewing.

When a conference call will not work

Most problems have one of a handful of causes. Work through the one that matches what you see. For general call problems that also affect one-to-one calls, see Telegram calls not working.

You cannot find the option to start one

How to recognise it: the Calls section only lets you call one person, or you see no option to create a link.

1. Update Telegram from the official app store or from Telegram's website.
2. Restart the app after the update.
3. Look again in the Calls section and in the call screen during a one-to-one call.

If it is still missing, your platform's app may not have the feature yet, or it may be rolling out. Try another device, such as Telegram Desktop.

Someone cannot join

How to recognise it: the link opens but the call does not, or the app says the call is not supported.

1. Ask the person to update their app.
2. If they are in a browser, ask them to open the link in the Telegram app instead.
3. Check that the call is still running. A link to a call that has ended will not put anyone in it.
4. If the call was full or the link was replaced, send a fresh link.

People cannot hear you, or you cannot hear them

How to recognise it: the call connects, names appear, but audio is missing one way.

1. Check that you are not muted on the call screen.
2. On a phone, make sure Telegram has microphone permission in the phone's settings.
3. On a computer, check the selected microphone and speakers in Telegram's call settings.
4. Disconnect Bluetooth headphones and try the phone's own speaker, then reconnect.

If one person has the problem in every call, the cause is on their device.

The call drops or freezes

How to recognise it: video freezes, voices break up, or the call ends unexpectedly.

1. Turn your camera off to save bandwidth.
2. Move to a better Wi-Fi signal or switch between Wi-Fi and mobile data.
3. If you use a proxy or VPN, try without it, or try a different server.
4. On Android, allow Telegram to run in the background without battery restrictions.

The emoji do not match

How to recognise it: participants read out different emoji for the same moment in the call.

1. Check that everyone is looking at the current emoji. If someone just joined, the key may have changed a second ago. Compare again.
2. If they still differ, end the call.
3. Start a new call, ideally by adding people directly rather than by a link that may have been shared.
4. Compare emoji again at the start.

Persistent mismatches are rare and worth taking seriously. Do not continue a sensitive conversation on a call that fails the check.

Common mistakes

• Posting the call link publicly. A link in a public group or channel works for everyone who reads it. Send it privately.
• Skipping the emoji check for sensitive calls. Encryption without verification protects against most problems, but the check is what proves nobody is in the middle.
• Assuming encryption stops recording. Anyone on the call can record it. Encryption only keeps outsiders out.
• Using a group's video chat when privacy is the point. A group's video chat is not end-to-end encrypted. Use a conference call for private meetings.
• Reusing one link indefinitely. Old links accumulate in chats and get forwarded. Create a new one per meeting.
• Joining from an old app. Many "the call does not work" reports come down to one participant who has not updated.
• Trusting a call link from a stranger. Treat unexpected call invitations the way you would treat unexpected links in messages.

FAQ

Do I need a group to make a group call on Telegram?

No. A conference call is a group call that is not attached to any group or channel. You start it from the Calls section, from a call link, or by adding people to a one-to-one call.

Are Telegram conference calls end-to-end encrypted?

Yes. Telegram describes conference calls as end-to-end encrypted, and you can verify it by comparing the four emoji shown on each participant's screen. If they all match, the call is secure.

How many people can join a conference call?

Telegram's announcement of the feature allowed adding up to 200 participants to an active call. Limits can change, so check inside the app if you are planning a large call. For very large audiences, a group video chat or a channel live stream is the better fit.

Can people join without a Telegram account?

They need a Telegram account to join. A call link can be sent anywhere, including by email, but opening it leads into Telegram.

Can I schedule a conference call?

You can create a call link in advance and send it with the time. Nobody is rung automatically, so people need to open the link at the agreed time. Scheduled video chats with reminders are a group and channel feature.

Why do the emoji change during the call?

The emoji are a fingerprint of the call's current key. When someone joins or leaves, the key changes, so the emoji can change too. Compare again after the participant list changes.

Summary

A Telegram conference call is an end-to-end encrypted group call with no group behind it. Start one from the Calls section by picking several contacts, create a call link to share in advance, or add a person to a call you are already on. Keep everyone's app up to date and use the Telegram app rather than a browser. At the start of any sensitive call, compare the four emoji. Send links privately, make a fresh one for each meeting, and remember that encryption keeps outsiders out but cannot stop someone inside the call from recording it. For community calls, use a group's video chat instead; for a wider look at calling features, see our guide to video calls and group video calls.
