How to Fix Telegram Calls Connecting With No Voice on Either Side

You join a Telegram call, the timer starts running, and the other person appears connected, yet neither of you can hear anything. No voice on your side, no voice on their side, just silence. This is one of the most frustrating Telegram problems because the call itself looks successful, so there is no obvious error to work from.

The good news is that silent calls are almost always caused by a small setting, a permission, or a network block, not by a broken account. Work through the checks below in order and you will usually find the cause within a few minutes.

Quick Answer

Most Telegram calls with no voice are caused by the microphone permission being switched off, a Bluetooth device stealing the audio, or a network or VPN blocking voice traffic. First, check that Telegram is allowed to use your microphone, disconnect any Bluetooth headset you are not using, and test the call on a different network. If the call works on mobile data but not on Wi-Fi, your router or internet provider is blocking the voice connection.

Check the Basics First

Before changing any deep settings, rule out the simple causes. Many silent calls are fixed by one of these quick checks.

• Turn your phone volume up and make sure media volume, not just ringtone volume, is raised.
• Check that you have not accidentally tapped the mute button inside the call screen.
• Remove your phone case if it covers the speaker or microphone holes.
• Restart the Telegram app completely, then try the call again.
• Ask the other person to do the same checks, because the problem may be on their side.

If you can hear other apps, such as music or videos, but not Telegram, the issue is inside Telegram or its permissions. If nothing on the phone makes sound, the problem is with the device itself.

Fix Microphone and Speaker Permissions

Telegram cannot send your voice if the app does not have permission to use the microphone. Updates, new phones, and privacy settings can switch this permission off without warning.

On Android

1. Open your phone Settings and tap Apps.
2. Find Telegram in the list and tap Permissions.
3. Tap Microphone and select Allow only while using the app.
4. Go back and make sure Phone and Notifications are also allowed.
5. Open Telegram and start a test call.

On iPhone

1. Open Settings and scroll down to Telegram.
2. Switch the Microphone toggle on.
3. Also check Settings, then Privacy and Security, then Microphone, and confirm Telegram is listed and enabled.
4. Return to Telegram and try the call again.

On a computer, check your system sound settings as well. In Windows, open Sound settings and confirm the correct microphone and speakers are selected as the default input and output devices. Inside Telegram Desktop, open Settings, then Advanced, then check the call input and output device choices.

Check Bluetooth and Audio Output

A very common hidden cause is Bluetooth. If your phone is connected to a car system, a smartwatch, wireless earbuds left in another room, or a Bluetooth speaker, Telegram may send the call audio there. You hear silence because the sound is playing somewhere else.

During the call, tap the speaker or audio output button on the call screen and choose your phone speaker manually. If that fixes the sound, turn Bluetooth off completely for the next call to confirm.

Test Your Network Connection

Voice calls need a steady two-way connection. Telegram may connect the call using one type of traffic, then fail to carry the actual voice because a firewall, router setting, or provider blocks it.

1. Switch from Wi-Fi to mobile data and try the call again.
2. If the call works on mobile data, restart your router and try Wi-Fi again.
3. Turn off any VPN, proxy, or private DNS app and retest. VPNs often block or slow voice traffic.
4. If you use Telegram’s built-in proxy, open Settings, then Data and Storage, then Proxy, and disable it for the test.
5. Try a call on a completely different network, such as a friend’s Wi-Fi, to confirm where the block sits.

On office, school, or hotel networks, voice calling is often blocked on purpose. In that case, your own mobile data is the simple workaround.

Clear Cache and Update Telegram

A damaged cache or an old app version can break audio handling. Clearing the cache does not delete your chats, because Telegram stores messages on its servers.

1. Open Telegram Settings, then Data and Storage, then Storage Usage.
2. Tap Clear Cache and confirm.
3. Open your app store and install any pending Telegram update.
4. Restart your phone after the update.
5. Place a short test call to check both directions of audio.

If the problem started right after an update, check the official Telegram frequently asked questions page for known issues, and make sure you are using the official app from the app store rather than an old third-party build.

Check In-App Call Settings and Test Voice

Telegram lets you test your setup before a real call matters. Send yourself a voice message in your Saved Messages chat. Play it back. If you cannot hear your own recording, the microphone or playback path is the problem. If the recording sounds clear, your device is fine and the fault is likely network related or on the other person’s side.

Also try a group voice chat or a call with a different contact. If one person is always silent but others work, ask that person to check their own microphone permission and Bluetooth. Silent calls are very often a one-sided problem that looks like a two-sided one.

On desktop, test with a headset and without one. A faulty USB headset or a wrong default device in the system settings is a frequent cause of complete silence on computers.

Check Data Saver, Battery, and App Restrictions

Modern phones try hard to save battery and mobile data, and voice calls can suffer because of it. If your phone restricts Telegram from using data freely in the background, or puts the app to sleep aggressively, the call may connect but fail to carry sound properly.

On Android, open Settings, then Apps, then Telegram, then Mobile Data, and allow background data and unrestricted data use. Then open Battery settings for the app and choose Unrestricted if it is available. On Samsung phones, also check the list of sleeping apps under Battery and Device Care, and remove Telegram from it. On iPhone, open Settings, then General, then Background App Refresh, and confirm Telegram is allowed.

Also test with Low Power Mode or Battery Saver switched off. These modes reduce background activity, and while a call is on screen they should not normally block audio, real-world results vary by phone model. Turning them off for one test call quickly shows whether they are part of your problem.

Common Mistakes to Avoid

• Do not reinstall Telegram before checking permissions. Reinstalling rarely fixes a permission problem, and you may face a login code delay.
• Do not assume the other person is at fault. Test with two different contacts before deciding.
• Do not leave a VPN running while testing. It changes the result and hides the real cause.
• Do not ignore Bluetooth. Earbuds in a pocket or a car connection are the silent cause in many cases.
• Do not turn on battery saver during calls. Aggressive battery saving can restrict Telegram in the background and affect audio.

Conclusion

A Telegram call that connects with no voice on either side is usually fixed by allowing microphone access, choosing the correct audio output, or removing a network block such as a VPN or strict Wi-Fi. Work through the checks in order, test with a voice message in Saved Messages, and confirm with a second contact. Once you find which step restores sound, you have found your cause, and the same fix will solve it if it returns.

Frequently Asked Questions

Why can the other person hear me but I cannot hear them?

This usually points to your speaker, your audio output choice, or a Bluetooth device taking the sound. Tap the output button during the call, select the phone speaker, and raise the media volume.

Why do Telegram calls have no sound only on Wi-Fi?

Your router, network firewall, or internet provider is likely blocking voice traffic. Restart the router, disable any VPN or proxy, and if the network belongs to a workplace or school, use mobile data instead.

Does clearing the Telegram cache delete my chats?

No. Your chats are stored on Telegram servers. Clearing the cache only removes temporary downloaded files from your device, and the app downloads them again when needed.

How can I test my microphone before making a call?

Record a voice message in your Saved Messages chat and play it back. If the recording is clear and audible, your microphone and speaker are working correctly.

What should I do if no fix works?

Update Telegram, restart the device, and test on a different network with a different contact. If silence continues on every call, report the problem through Telegram Settings, then Help, and include your device model and app version.
