Telegram Calls Not Working: Fixes

Telegram calls usually fail for one of five reasons: the other person's privacy settings do not allow your call, the app lacks microphone or camera permission, the network blocks the kind of traffic calls use, a battery saver stops incoming calls from ringing, or the app is out of date. Work out which symptom you have, then jump to the matching section below.

This guide is about one-to-one voice and video calls. For how calls, group calls and screen sharing work in general, see our guide to video calls and group video calls.

Match your symptom to a cause

Different failures point to different causes, so start here.

• You see a message that you cannot call this person: their privacy settings, or a block. See Cause 1.
• The call connects but nobody hears you, or the camera is black: permissions or audio routing. See Cause 2 and Cause 6.
• It stays on "Connecting" or "Requesting" and then drops: the network. See Cause 3 and Cause 4.
• Your phone never rings when someone calls you: notification and battery settings. See Cause 5.
• Calls worked yesterday and broke after an update: see Cause 7.
• Only video fails while voice works: usually bandwidth or camera permission. See Cause 2 and Cause 3.

How Telegram calls travel

Calls are end-to-end encrypted and use a different path from normal messages. Telegram's developer documentation explains that call audio and video go either straight between the two devices (peer-to-peer) or through Telegram's relay servers when a direct path is not possible.

That matters for troubleshooting. Your messages can arrive perfectly while calls fail, because calls depend on real-time traffic that some Wi-Fi networks, firewalls, VPNs and proxies handle badly. "Messages work" does not prove "the network is fine for calls".

Cause 1: Privacy settings or a block

How to recognise it: Telegram tells you straight away that you cannot call this user, often mentioning their privacy settings. The call never starts ringing.

Every Telegram user chooses who can call them: everybody, their contacts, or nobody, with exceptions for specific people. If they chose contacts only and you are not in their contacts, the call is refused. A block has the same effect.

1. Send a normal message and ask whether they are happy to take calls.
2. Ask them to add you as a contact, or to add you to their "always allow" list for calls.
3. If they have blocked you, there is nothing to fix. Our guide on whether someone blocked you explains what Telegram shows.

Check your own side too. If nobody can call you, open Settings, then Privacy and Security, then Calls, and see who you allow. A setting of Nobody blocks every incoming call.

Cause 2: Missing microphone or camera permission

How to recognise it: the call connects and the timer runs, but the other person hears silence, or video shows a black frame.

Permissions on Android

1. Open phone Settings, then Apps, then Telegram, then Permissions.
2. Allow Microphone and Camera. "Only while using the app" is fine for calls you make.
3. Some phones also have a quick privacy toggle in the notification shade that blocks the microphone or camera for every app. Make sure it is off.

Permissions on iPhone

1. Open the iPhone Settings app, scroll to Telegram.
2. Turn on Microphone and Camera.
3. Check Screen Time content restrictions, which can block microphone access for all apps.

Permissions on Desktop and Web

• On Windows and macOS, the operating system's privacy settings decide whether apps may use the microphone and camera. Allow Telegram there.
• In Telegram Desktop, open the call settings and choose the right input and output device. A laptop with a headset plugged in often picks the wrong one.
• In a browser using Telegram Web, allow the microphone and camera when the site asks. If you clicked "block" before, change it in the site permissions next to the address bar.

If it does not work: test the microphone in another app. If no app can use it, the problem is the device, not Telegram.

Cause 3: A weak or unstable connection

How to recognise it: calls connect, then the audio breaks up, freezes, or the call drops after a few seconds. Video suffers first.

1. Switch between Wi-Fi and mobile data to see whether one works better.
2. Move closer to the router, or away from crowded public Wi-Fi.
3. Turn off downloads and video streaming on the same network during the call.
4. Try a voice call before a video call; voice needs far less bandwidth.
5. Look in Telegram's data and storage settings for an option to use less data for calls, if your version has one. It trades quality for stability.

If Telegram itself keeps showing "Connecting" at the top of the chat list, the problem is broader than calls. See Telegram stuck on connecting.

Cause 4: VPNs, proxies, firewalls and restricted networks

How to recognise it: messages send instantly but every call stays on connecting, on one network in particular, such as a workplace, school, hotel, or with a VPN switched on.

Real-time calls need traffic that some networks block or that some VPNs and proxies do not carry well.

1. Turn the VPN off and try again. If the call now works, check the VPN's settings for an option that allows this kind of traffic, or exclude Telegram from the VPN.
2. If you use a proxy inside Telegram, try without it. Not every proxy type can carry calls, and some Telegram versions show a separate switch to use the proxy for calls. Our Telegram proxy guide explains the proxy types.
3. On a work or school network, try mobile data instead. Network administrators often block call traffic, and only they can change that.
4. In some countries, internet calls on many apps are restricted by networks or authorities. If calls fail only in one country, that may be the reason. See where Telegram is banned or restricted for background.

The peer-to-peer setting

In the Calls privacy settings, a peer-to-peer option decides whether calls may connect directly to the other device. Telegram's own help text for it explains the trade-off: turning it off sends the call through Telegram's servers, which hides your IP address from the other person but may lower quality a little.

Changing it is worth trying in both directions. On some strict networks a relayed call connects when a direct one fails. On others the reverse is true.

Cause 5: Incoming calls do not ring

How to recognise it: people say they called you, but you only see a missed call later, or nothing at all.

Ringing on Android

1. In Telegram's notification settings, make sure calls notifications are on and have a ringtone.
2. In Android settings for Telegram, allow notifications, including the category used for calls.
3. Under Battery for Telegram, choose unrestricted. Battery optimisation is the most common reason incoming calls are missed.
4. On newer Android versions, check special app access for full-screen notifications. Without it, an incoming call may arrive as a quiet banner on a locked screen.
5. Check Do Not Disturb exceptions.

Ringing on iPhone

1. In the iPhone Settings app, allow notifications for Telegram.
2. Check Focus modes. A Focus that silences Telegram also silences its calls unless Telegram is allowed in it.
3. Telegram on iPhone can show calls through the system call screen. If calls behave oddly, look in Telegram's call or notification settings for that integration option and try switching it.

For message notifications that also fail, see Telegram notifications not working.

Cause 6: Audio goes to the wrong place

How to recognise it: you hear nothing, or the other person hears an echo, or sound comes from the earpiece when you expected a speaker.

1. Check whether a Bluetooth headset, car system or smartwatch is connected. Calls often route to it automatically.
2. During the call, use the speaker or audio button to pick the output.
3. On Desktop, select the input and output devices in the call settings, and check the volume mixer of the operating system.
4. Echo usually means one side is on a loud speaker. Using headphones on one side fixes it.

Cause 7: An outdated or broken app

How to recognise it: calls stopped working after an update, after a long time without one, or crash the app.

1. Update Telegram on both devices. Calls rely on both apps speaking a compatible version.
2. Restart the phone.
3. Clear Telegram's cache, which does not delete chats. See how to clear Telegram's cache.
4. As a last step, reinstall. Your chats are in the cloud, but secret chats are not and are lost when you log out.

If the app crashes as soon as a call opens, our guide to Telegram crashing on Android or iPhone goes further.

Worked example: calls fail only at the office

Example scenario. Sam can call friends from home but every call on office Wi-Fi stays on connecting, while messages are fine. Sam switches the phone to mobile data during lunch and the call connects at once. That isolates the office network. Turning off the peer-to-peer option makes no difference, so the network blocks call traffic completely. Sam either uses mobile data for calls at work or asks IT, who may have a policy reason for the block.

Common mistakes

• Reinstalling first. It rarely fixes calls and can cost local data. Settings and network checks find most problems in minutes.
• Assuming a block. Most "cannot call" messages come from privacy settings, which a friendly message can resolve.
• Testing only one network. Without switching networks you cannot tell a phone problem from a network problem.
• Forgetting the other device. If one side has an old app, no microphone permission or a poor connection, the call fails for both.
• Using a random public proxy to fix calls. Many free proxies do not carry calls at all, and you are routing traffic through a stranger's server.

FAQ

Why does Telegram say I cannot call someone?

They have limited who can call them, or they have blocked you. Ask them by message whether they take calls and whether they can add you as an exception.

Are Telegram calls encrypted?

Yes. Voice and video calls are end-to-end encrypted. Telegram shows emoji on both screens that you can compare to confirm the connection.

Do Telegram calls use a lot of data?

Video uses far more than voice. If data is a concern, use voice calls, Wi-Fi, or the reduced data option for calls. Our guide on how much data Telegram uses has more.

Why do group calls work but personal calls do not, or the reverse?

Group calls and video chats use a different setup from one-to-one calls, and privacy settings for personal calls do not apply to them. A failure in only one type points to settings rather than your microphone.

Can I call someone who is not in my contacts?

Yes, if their privacy settings allow calls from everybody. If they allow contacts only, you need to be in their contacts first.

Summary

Read the symptom first. A refusal message points to privacy settings or a block. Silence points to permissions or audio routing. Endless connecting points to the network, a VPN, a proxy or local restrictions. Missed calls point to notification and battery settings. Change one thing at a time, test on a second network, and make sure both people have an updated app.
