Calling is a core feature of CometChat.

​
Prerequisites

  1. CometChat Core SDK installed.
  2. Performed the steps mentioned in the Setup guide
Add the CometChat Calls Dependencyv2.4+ onwards, Voice & Video Calling functionality has been moved to a separate library. Please add the following dependency to your app-level build.gradle file in case you plan on using the Voice and Video Calling feature. dependencies { implementation ‘com.cometchat:pro-android-calls-sdk:2.3.0’ }
CometChat allows two mechanisms for calling
  1. Direct Calling
  2. Default Calling

​
Direct Calling

Direct Calling allows you to start the call/conference sessions directly with the session Id of your choice. All the users joining the same session Id are connected to the same call/conference. For more information on Direct Calling, please visit the Direct Calling docs.

​
Default Calling

The second approach that CometChat allows is to implement the entire calling flow where one user initiates a call/conference and other user/users who want to be a part of the call accept/reject the call. All the users that accept the call are connected to the same session. For more information on Default Calling, please visit the Default Calling docs.
