The situation when Telegram does not emit a sound signal when there is an incoming call is a common problem for users of Androidsmartphones. You may see a call notification on your lock screen or curtain, but your phone remains silent and you miss important conversations. This causes irritation, especially if the call concerns work issues or urgent matters.
The reasons for this behavior of the messenger can vary from a simple silent mode switch to complex system restrictions imposed by MIUI, EMUI or OneUI. The operating system often aggressively conserves battery power by putting background processes to sleep, resulting in delayed or no sound. In this article, we will analyze in detail all possible factors and ways to eliminate them.
Checking the internal settings of the messenger
First of all, you need to make sure that the problem does not lie in the application settings themselves. The developers Telegram provided for a flexible notification system that the user could accidentally change. Go to the menu and select Settings → Notifications and sounds. Here you will see the “Calls” section.
Make sure the Sound switch is active. If it is turned off, then even with the phone volume at maximum, the call will be silent. Also check the “Ringtone” item. Sometimes users accidentally install an empty audio file or a file that has been deleted from the device’s memory.
- 🔊 Check if the “Mute” option is checked in the profile of a particular contact.
- 🎵 Make sure that the standard melody is selected and not a custom file that could be damaged.
- 📢 Test the media and call volume separately through the engineering menu or system settings.
It is important to note that notification settings for groups and channels do not affect personal calls, but the overall sound profile may be affected by global system changes. If you recently updated the application, the settings may have been reset to default. Resetting notification settings within the application often solves the problem if system permissions are fine.
Android system permissions and notification channels
Starting with version Android 8.0, the notification management system has become more detailed. Now each alert type has its own “channel”. If the “Incoming calls” channel in the application system settings is muted, then the internal settings Telegram will not have any effect.
Go to Settings → Applications → Telegram → Notifications. Here you will find a list of categories. Find the "Calls" or "Calls" category. Click on it and make sure the sound is unmuted and the importance is set to High or Urgent. Without this, the system may consider the call to be a normal background event and not wake up the screen.
Also check the application permissions. Log in Settings → Applications → Telegram → Permissions. Make sure access to your microphone and contacts is allowed. Although lack of access to the microphone does not always block incoming audio, it can disrupt the protocol VoIPthat the messenger uses to transmit voice.

The impact of power saving mode and battery optimization
One of the most common reasons for the lack of sound is aggressive battery optimization, built into the shells of smartphone manufacturers. Systems MIUI from Xiaomi, ColorOS from Oppo or standard power saving mode Android can completely stop running Telegram in the background to save battery.
When the screen is off, the system freezes the application. At the moment of an incoming call, the system simply does not have enough time to “unfreeze” the process and play the audio file before the call is dropped or goes into “Missed” mode. You need to add the application to the exceptions.
To do this, go to Settings → Battery → Battery Saver (the path may differ depending on the model). Find Telegram in the list and select the “No restrictions” or “Do not limit” option. This will allow the application to constantly maintain a connection with the server and instantly respond to incoming events.
⚠️ Attention: Disabling battery optimization for messengers may slightly increase battery consumption during the day, but this is necessary for stable calls.
Specifics of Xiaomi and Huawei shells
On Xiaomi devices, you must also enable “Autostart” for Telegram in the “Security” application. On Huawei/Honor, you need to allow background work manually through the phone manager, otherwise the system will kill the process 10 minutes after the screen turns off.
Conflicts with Do Not Disturb mode and sound profiles
Do Not Disturb mode is a common culprit of silence. Even if the volume slider is turned up to maximum, this mode programmatically blocks all sound signals except the alarm clock or calls from selected contacts. Check the status of this mode in the notification shade.
Go to Settings → Sound and vibration → Do not disturb. Make sure the mode is turned off. If you use it regularly, set up exceptions. Add Telegram or specific contacts to the allowed list so that calls from them can be made even during quiet hours.
It is also worth paying attention to the physical buttons and profiles. Some smartphones have a mode switch on the body or in the quick access menu that changes the profile to “Vibration” or “Silent”. Make sure that the “Sound” profile is selected.
| Phone mode | Impact on Telegram call | How to fix |
|---|---|---|
| Normal (Sound) | Call is heard | No need to do anything |
| Vibration | Only vibration, no sound | Press the volume button and change mode |
| Do not disturb | Complete silence (usually) | Disable in settings or add exceptions |
| Energy saving | Delay or lack of sound | Disable optimization for the application |
Problems with Internet connection and VoIP
Calls to Telegram work using technology VoIP (Voice over IP), which means voice transmission over the Internet. If the connection is unstable, the data packet that initiates the call and signal may be lost. As a result, you see a missed call, but the phone itself did not record the moment of the call.
Check whether the traffic saving mode is enabled in the mobile data settings. This mode often blocks background data transfer for applications that are not whitelisted. Go to Settings → Network and Internet → Traffic saving and allow Telegram to use data in the background.
If you use VPN or proxy servers inside the application, try disabling them for the duration of the test. An unstable tunnel can create delays that cause the call to arrive late when the phone has already gone to sleep or dropped the connection.
Try switching from Wi-Fi to mobile data (or vice versa) during the test. If the problem disappears on one of the connection types, then the problem is in the settings of the router or the operator's tariff.
Outdated version of the application and cache
Accumulated errors in the application cache or an outdated version of the software can cause conflicts with new versions of the operating system Android. Developers constantly release patches that fix bugs with notifications and work in the background.
Go to Google Play Market or Galaxy Store and check for updates. If the Update button is active, be sure to follow the procedure. If the app is already updated, try clearing the cache. This will not delete your correspondence, but it will reset temporary files that may have become corrupted.
To clear, go to Settings → Applications → Telegram → Storage and click Clear cache. Do not confuse this button with “Clear data”, since the latter action will require re-authorization into your account.
⚠️ Attention: If you use third-party Telegram clients (for example, Plus Messenger or Graph Messenger), the problem may be on the side of the modification developer. Try installing the official version to check.
Frequently asked questions (FAQ)
Why is the call in Telegram heard only when the screen is on?
This is a classic symptom of the energy saving system. When the screen goes dark, the processor puts the application into sleep mode. When you make a call, the system takes time to wake up the application, which is not enough to play sound. The solution is to disable battery optimization for Telegram in the system settings.
Can a third-party antivirus block call audio?
Yes, some antiviruses and cleaners have spam blocking and permission management functions. They may mistakenly classify a VoIP call as an unwanted event and mute it. Check your antivirus settings and add Telegram to trusted applications.
What to do if there is sound, but it is very quiet?
Check the volume settings specifically for media or ringing during an incoming call. Also make sure that the speaker is not clogged with dust. In rare cases, resetting accessibility settings can help if audio enhancement functions for the hearing impaired have been turned on and are not working correctly.
Does the Android version affect the operation of calls?
Yes, in new versions of Android (12, 13, 14), the rules for running applications in the background have become more stringent. On older versions (Android 9 and below), problems are more often associated with a lack of RAM. Owners of new smartphones need to more carefully configure permissions and disable optimization.
Comprehensive check of notification, battery and network settings in 95% of cases returns the sound of incoming calls to Telegram.
