Group voice calling is a useful feature, especially during this time when most of us are at home, but we may need to talk to multiple people (e.g. colleagues). WhatsApp has already brought this feature to users . But now, group voice calling is also available on Telegram.

How can you make a group Telegram voice call on Android?
The latest Telegram beta version 7.3.0 experimentally offers the ability for group voice calls:
First, you need to download the Telegram Beta version for Android.
Next, you need to create a group and tap on the group header to expand it. Here, you will find the list of group members, notification settings, etc. Tap on the three vertical dots icon located in the top right corner and select “Start voice chat”.
A pop-up window will appear asking you to confirm your choice. (There is also a checkbox that allows only admins to speak. This is to ensure that non-admin group members can only listen. Additionally, the ability to initiate calls is only accessible to those members who are admins.)
When you start a group voice call, you're muted by default. Before you can speak, you need to press the large unmute button or hold the microphone.
When you are muted, the microphone button will remain green and show which members are speaking or listening.

How to make a group Telegram voice call on iOS?
To make a Telegram group voice call on iOS, you'll first need to download the beta version for iOS. The rest of the steps are essentially the same as on Android.
The addition of this feature to Telegram is considered important for many users who want to talk to multiple people. We can certainly expect improvements to the feature before it is released in the stable version.
