​
Overview

The CometChatOutgoingCall Component is a visual representation of a user-initiated call, whether it’s a voice or video call. It serves as an interface for managing outgoing calls, providing users with essential options to control the call experience. This component typically includes information about the call recipient, call controls for canceling the call, and feedback on the call status, such as indicating when the call is in progress.

​
Usage

​
Integration

CometChatOutgoingCall being a custom component, offers versatility in its integration. It can be seamlessly launched via button clicks or any user-triggered action, enhancing the overall user experience and facilitating smoother interactions within the application. 
import { CometChat } from "@cometchat/chat-sdk-react-native";
import {
  CometChatOutgoingCall,
  CometChatUiKitConstants,
} from "@cometchat/chat-uikit-react-native";

function App(): React.JSX.Element {
  const [call, setCall] = useState<CometChat.Call>();

  useEffect(() => {
    //login
    const callObject = new CometChat.Call(
      "receiver-uid",
      CometChatUiKitConstants.MessageTypeConstants.audio,
      CometChatUiKitConstants.ReceiverTypeConstants.user
    );

    CometChat.initiateCall(callObject)
      .then((c) => {
        setCall(c);
      })
      .catch(console.log);
  }, []);

  return <>{call && <CometChatOutgoingCall call={call} />}</>;
}

​
Actions

Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.
onEndCallButtonPressed
The onEndCallButtonPressed action is typically triggered when the end call button is pressed, carrying out default actions. However, with the following code snippet, you can effortlessly customize or override this default behavior to meet your specific needs. 
import { CometChat } from "@cometchat/chat-sdk-react-native";
import {
  CometChatOutgoingCall,
  CometChatUiKitConstants,
} from "@cometchat/chat-uikit-react-native";

function App(): React.JSX.Element {
  const [call, setCall] = useState<CometChat.Call>();

  useEffect(() => {
    //login
    const callObject = new CometChat.Call(
      "receiver-uid",
      CometChatUiKitConstants.MessageTypeConstants.audio,
      CometChatUiKitConstants.ReceiverTypeConstants.user
    );

    CometChat.initiateCall(callObject)
      .then((c) => {
        setCall(c);
      })
      .catch(console.log);
  }, []);

  const cancelCall = (c: CometChat.Call) => {
    //code
    CometChat.endCall(c.getSessionId()).then(() => {
      setCall(undefined);
    });
  };

  return (
    <>
      {call && (
        <CometChatOutgoingCall
          call={call}
          onEndCallButtonPressed={cancelCall}
        />
      )}
    </>
  );
}
onError
You can customize this behavior by using the provided code snippet to override the onError and improve error handling. 
import { CometChat } from "@cometchat/chat-sdk-react-native";
import {
  CometChatOutgoingCall,
  CometChatUiKitConstants,
} from "@cometchat/chat-uikit-react-native";

function App(): React.JSX.Element {
  const [call, setCall] = useState<CometChat.Call>();

  useEffect(() => {
    //login
    const callObject = new CometChat.Call(
      "receiver-uid",
      CometChatUiKitConstants.MessageTypeConstants.audio,
      CometChatUiKitConstants.ReceiverTypeConstants.user
    );

    CometChat.initiateCall(callObject)
      .then((c) => {
        setCall(c);
      })
      .catch(console.log);
  }, []);

  const cancelCall = (c: CometChat.Call) => {
    //code
    CometChat.endCall(c.getSessionId()).then(() => {
      setCall(undefined);
    });
  };

  return (
    <>
      {call && (
        <CometChatOutgoingCall
          call={call}
          onEndCallButtonPressed={cancelCall}
          onError={err => {
            console.log('Handle error:', err);
          }
        />
      )}
    </>
  );
}

​
Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK. The OutgoingCall component does not have any exposed filters.

​
Events

Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed. The list of events emitted by the Incoming Call component is as follows.
EventDescription
ccCallEndedThis event is triggered when the initiated call successfully ends.
ccCallFailledThis event is triggered when an error occurs during the intiated call.
import { CometChatUIEventHandler } from "@cometchat/chat-uikit-react-native";

CometChatUIEventHandler.addCallListener("CALL_LISTENER_ID", {
  ccCallEnded: ({ call }) => {
    //code
  },
});

CometChatUIEventHandler.addCallListener("CALL_LISTENER_ID", {
  ccCallFailled: ({ call }) => {
    //code
  },
});

import { CometChatUIEventHandler } from "@cometchat/chat-uikit-react-native";

CometChatUIEventHandler.removeCallListener("CALL_LISTENER_ID");

​
Customization

To fit your app’s design requirements, you can customize the appearance of the conversation component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

​
Style

Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component. 
import { CometChat } from "@cometchat/chat-sdk-react-native";
import {
  CometChatOutgoingCall,
  CometChatUiKitConstants,
} from "@cometchat/chat-uikit-react-native";

function App(): React.JSX.Element {
  const [call, setCall] = useState<CometChat.Call>();

  useEffect(() => {
    //login
    const callObject = new CometChat.Call(
      "receiver-uid",
      CometChatUiKitConstants.MessageTypeConstants.audio,
      CometChatUiKitConstants.ReceiverTypeConstants.user
    );

    CometChat.initiateCall(callObject)
      .then((c) => {
        setCall(c);
      })
      .catch(console.log);
  }, []);

  const cancelCall = (c: CometChat.Call) => {
    //code
    CometChat.endCall(c.getSessionId()).then(() => {
      setCall(undefined);
    });
  };

  return (
    <>
      {call && (
        <CometChatOutgoingCall
          call={call}
          onEndCallButtonPressed={cancelCall}
          style={{
            avatarStyle: {
              containerStyle: {
                borderRadius: 8,
              },
              imageStyle: {
                borderRadius: 8,
              },
            },
            endCallButtonStyle: {
              borderRadius: 8,
            },
          }}
        />
      )}
    </>
  );
}

​

callSettingsBuilderSets the CallSettingsBuilder for the outgoing call configuration.callSettingsBuilder={callSettingsBuilderObject}
customSoundForCallsUsed to set custom sound for callscustomSoundForCalls?: string
disableSoundForCallsUsed to disable/enable the sound of Outgoing calls, by default it is set to falsedisableSoundForCalls?: boolean

​
Advanced

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your views, layouts, and UI elements and then incorporate those into the component.

​
TitleView

Allows setting a custom list item view to be rendered for each conversation in the fetched call list. Use Cases:
  • Display the contact’s name in a unique style.
  • Show a call type indicator (Voice Call, Video Call).

        setCall(c);
      })
      .catch(console.log);
  }, []);

  const cancelCall = (c: CometChat.Call) => {
    //code
    CometChat.endCall(c.getSessionId()).then(() => {
      setCall(undefined);
    });
  };

  return (
    <>
      {call && (
        <CometChatOutgoingCall
          call={call}
          onEndCallButtonPressed={cancelCall}
          TitleView={(call: CometChat.Call | CometChat.CustomMessage) => {
