Learn how to cut down unwanted calls by setting your Telegram app to receive calls only from people who are in your contacts list, or choosing to get calls from absolutely no one.

Telegram lets you choose who can call you. With this, you can customize your incoming call settings to avoid getting phone calls from strangers by allowing calls only from your contacts. You can even go further and instruct the Telegram app to receive calls from nobody!
Note that while we are using an iPhone for these steps, the process for Android is nearly the same.
Set Telegram to receive calls only from your contacts or no one
- Open the Telegram app and tap Settings.
- Select Privacy and Security from the list of choices.
- Tap Calls from the Privacy section.
- Under Who Can Call Me, select My Contacts or Nobody.
- You can further customize this by adding exceptions. For instance, if you selected My Contacts, you can choose to never allow specific contacts or groups. And if you choose Nobody, you can still add some important people and groups under Always Allow to get calls from them.
In addition to this, you can also tweak other Telegram settings, such as who can add you to groups & channels, who can add a link to your account when forwarding your messages, and who can see your profile photo/last seen & online status/phone number.
Furthermore, the premium version of Telegram also lets you restrict receiving voice messages! All these options are available in Telegram Settings > Privacy and Security.
