​
Overview

The Call Button is a Component provides users with the ability to make calls, access call-related functionalities, and control call settings. Clicking this button typically triggers the call to be placed to the desired recipient.

​
Usage

​
Integration

import { CometChat } from "@cometchat/chat-sdk-javascript";
import { CometChatCallButtons } from "@cometchat/chat-uikit-react";
import React from "react";

const CallButtonDemo = () => {
  const [chatUser, setChatUser] = React.useState<CometChat.User>();
  React.useEffect(() => {
    CometChat.getUser("uid").then((user) => {
      setChatUser(user);
    });
  }, []);
  return <CometChatCallButtons user={chatUser} />;
};

export default CallButtonDemo;

​
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.
1. onError
This action doesn’t change the behavior of the component but rather listens for any errors that occur in the Call Button component. 
import { CometChat } from "@cometchat/chat-sdk-javascript";
import { CometChatCallButtons } from "@cometchat/chat-uikit-react";
import React from "react";

const CallButtonDemo = () => {
  const [chatUser, setChatUser] = React.useState<CometChat.User>();
  React.useEffect(() => {
    CometChat.getUser("uid").then((user) => {
      setChatUser(user);
    });
  }, []);

  const handleOnError = (error: CometChat.CometChatException) => {
    console.log("Your Custom on error actions", error);
  };

  return <CometChatCallButtons user={chatUser} onError={handleOnError} />;
};

export default CallButtonDemo;

​
Filters

You can set CallSettingsBuilder in the Call Buttons Component to customise the calling experience. To know more about the filters available please refer to CallSettingsBuilder. 
import { CometChat } from "@cometchat/chat-sdk-javascript";
import { CometChatCallButtons } from "@cometchat/chat-uikit-react";
import React from "react";

const CallButtonDemo = () => {
  const [chatUser, setChatUser] = React.useState<CometChat.User>();

  React.useEffect(() => {
    CometChat.getUser("uid").then((user) => {
      setChatUser(user);
    });
  }, []);

  const getCallSettingsBuilder = (call: CometChat.Call) => {
    return new CometChatCalls.CallSettingsBuilder()
      .setIsAudioOnlyCall(
        call?.getType() === CometChatUIKitConstants.MessageTypes.audio
          ? true
          : false
      )
      .build();
  };

  return (
    <CometChatCallButtons
      user={chatUser}
      callSettingsBuilder={getCallSettingsBuilder}
    />
  );
};

export default CallButtonDemo;

​
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 Call Buttons component is as follows.
EventDescription
ccCallRejectedThis event is triggered when the initiated call is rejected by the receiver.
ccCallEndedThis event is triggered when the initiated call successfully ends.
ccOutgoingCallThis event is triggered when the user initiates a voice/video call.
ccMessageSentThis event is triggered when the sent message is in transit and also when it is received by the receiver.
const ccCallRejected = CometChatCallEvents.ccCallRejected.subscribe(
  (call: CometChat.Call) => {
    //Your Code
  }
);

const ccCallEnded = CometChatCallEvents.ccCallEnded.subscribe(
  (call: CometChat.Call) => {
    //Your Code
  }
);

const ccOutgoingCall = CometChatCallEvents.ccOutgoingCall.subscribe(
  (call: CometChat.Call) => {
    //Your Code
  }
);

const ccMessageSent = CometChatMessageEvents.ccMessageSent.subscribe(() => {
  //Your Code
});

ccCallRejected?.unsubscribe();

ccCallEnded?.unsubscribe();

ccOutgoingCall?.unsubscribe();

ccMessageSent?.unsubscribe();
