# Voice Alerts/Notifications Broadcasting

> Broadcast voice messages to multiple recipients at once

<Tabs>
  <Tab title="Node">
    ## Overview

    This guide shows how to broadcast voice messages to multiple recipients at once. You can play recorded audio when the call recipient answers or use text-to-speech, as we show here.

    You can use voice broadcasting for use cases such as:

    * Bulk voice calling campaigns
    * Emergency notifications
    * Survey campaigns
    * User feedback
    * Announcements
    * Promotions and special deals
    * Reminder campaigns

    You can broadcast voice alerts either by using our PHLO visual workflow builder or our APIs and XML documents. Follow the instructions in one of the tabs below.

        Here’s how to broadcast voice alerts and notifications using XML.

        ## How it works

          <img src="https://mintcdn.com/plivo/M2NzHE_bNZbCm0gd/images/make-bulk-calls.png?fit=max&auto=format&n=M2NzHE_bNZbCm0gd&q=85&s=fea79ace9feb45bfb5ee7bbb98831781" alt="" width="1446" height="774" data-path="images/make-bulk-calls.png" />
        </Frame>

        Plivo requests an answer URL when the call is answered (step 4) and expects the file at that address to hold a valid XML response from the application with instructions on how to handle the call. To see how this works, you can use [https://s3.amazonaws.com/static.plivo.com/broadcast.xml](https://s3.amazonaws.com/static.plivo.com/broadcast.xml) as an answer URL to test your first outgoing call. The file contains this XML code:

        ```xml theme={null}
        <Response>
        <Speak>Congratulations! You have made your first bulk call.</Speak>
        </Response>
        ```

        This code instructs Plivo to say, “Congratulations! You have made your first bulk call” to the call recipients. You can find the entire list of valid Plivo XML verbs in our [XML Reference](/voice/xml/overview/) documentation.

        ## Prerequisites

        To get started, you need a Plivo account —  [sign up](https://cx.plivo.com/signup) with your work email address if you don’t have one already. If this is your first time using Plivo APIs, follow our instructions to [set up a Node.js development environment](/sdk/server/set-up-node-dev-environment-api-xml-voice/) and a web server and safely expose that server to the internet.

        ## Create voice alert broadcast application

        Create a file called `Broadcast.js` and paste into it this code.

        ```js theme={null}
        var plivo = require('plivo');

        (function main() {
            'use strict';

            var client = new plivo.Client("<auth_id>","<auth_token>");
            client.calls.create(
                "<caller_id>", // from
                "destination_number1<destination_number2", // to
                "https://s3.amazonaws.com/static.plivo.com/broadcast.xml", // answer url
                {
                    answerMethod: "GET",
                },
            ).then(function (response) {
                console.log(response);
            }, function (err) {
                console.error(err);
            });
        })();
        ```

        Replace the auth placeholders with your authentication credentials from the [Plivo console](https://cx.plivo.com/home). Replace the phone number placeholders with actual phone numbers in [E.164 format](https://en.wikipedia.org/wiki/E.164) (for example, +12025551234). Destination numbers may also be SIP endpoints, in which case each destination\_number placeholder must be a valid SIP URI — for example, sip:[john1234@phone.plivo.com](mailto:john1234@phone.plivo.com).

        <Note>
          <strong>Note:</strong> We recommend that you store your credentials in the `auth_id` and `auth_token` environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and it will automatically fetch them from the environment variables. You can use `process.env` to store environment variables and fetch them when initializing the client.
        </Note>

        ## Test

        Save the file and run it.

        rescue PlivoRESTError => e
          puts 'Exception: ' + e.message
        end
        ```

        Replace the auth placeholders with your authentication credentials from the [Plivo console](https://cx.plivo.com/home).

        ## Create voice alert broadcast application

        In Visual Studio, open the file in the CS project called `Program.cs` and paste into it this code.

        ```cs theme={null}
        using System;
        using System.Collections.Generic;
        using Plivo;

        namespace testplivo
        {
            class Program
            {
                static void Main(string[] args)
                {
                    var api = new PlivoApi("<auth_id>","<auth_token>");
                    var response = api.Call.Create(
                        to: new List<String> { "<destination_number1>", "<destination_number2>" },
                        from: "<caller_id>",
                        answerMethod: "GET",
                        answerUrl: "https://s3.amazonaws.com/static.plivo.com/broadcast.xml"
                    );
                    Console.WriteLine(response);
                }
            }
        }
        ```

        Replace the auth placeholders with your authentication credentials from the [Plivo console](https://cx.plivo.com/home). Replace the phone number placeholders with actual phone numbers in [E.164 format](https://en.wikipedia.org/wiki/E.164) (for example, +12025551234). Destination numbers may also be SIP endpoints, in which case each destination\_number placeholder must be a valid SIP URI — for example, sip:[john1234@phone.plivo.com](mailto:john1234@phone.plivo.com).

        This code instructs Plivo to say, “Congratulations!  You have made your first bulk call” to the call recipients. You can find the entire list of valid Plivo XML verbs in our [XML Reference](/voice/xml/overview/) documentation.

        ## Prerequisites

        To get started, you need a Plivo account —  [sign up](https://cx.plivo.com/signup) with your work email address if you don’t have one already. If this is your first time using Plivo APIs, follow our instructions to [set up a Ruby development environment](/sdk/server/set-up-ruby-dev-environment-api-xml-voice/) and a web server and safely expose that server to the internet.

        ## Create voice alert broadcast application

        Create a Java class in the project called `Broadcast` and paste into it this code.

        ```java theme={null}
        import java.io.IOException;
        import java.util.Collections;
        import com.plivo.api.Plivo;
        import com.plivo.api.exceptions.PlivoRestException;
        import com.plivo.api.models.call.Call;
        import com.plivo.api.models.call.CallCreateResponse;

        class MakeCall {
            public static void main(String [] args) throws IOException, PlivoRestException {
                Plivo.init("<auth_id>","<auth_token>");
                CallCreateResponse response = Call.creator("<caller_id>",
                        Collections.singletonList("<destination_number1>", "<destination_number2>"),
                        "https://s3.amazonaws.com/static.plivo.com/broadcast.xml")
                        .answerMethod("GET")
                        .create();
                System.out.println(response);
            }
        }
        ```

        Replace the auth placeholders with your authentication credentials from the [Plivo console](https://cx.plivo.com/home). Replace the phone number placeholders with actual phone numbers in [E.164 format](https://en.wikipedia.org/wiki/E.164) (for example, +12025551234). Destination numbers may also be SIP endpoints, in which case each destination\_number placeholder must be a valid SIP URI — for example, sip:[john1234@phone.plivo.com](mailto:john1234@phone.plivo.com).

        <Note>
          <strong>Note:</strong> We recommend that you store your credentials in the `auth_id` and `auth_token` environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and it will automatically fetch them from the environment variables. You can use [System.getenv()](https://docs.oracle.com/javase/tutorial/essential/environment/env.html) to store environment variables and retrieve them when initializing the client.
        </Note>

    ## Overview

    This guide shows how to broadcast voice messages to multiple recipients at once. You can play recorded audio when the call recipient answers or use text-to-speech, as we show here.

    You can use voice broadcasting for use cases such as:

    * Bulk voice calling campaigns
    * Emergency notifications
    * Survey campaigns
    * User feedback
    * Announcements
    * Promotions and special deals
    * Reminder campaigns

    You can broadcast voice alerts either by using our PHLO visual workflow builder or our APIs and XML documents. Follow the instructions in one of the tabs below.

    <Tabs>

        Here’s how to broadcast voice alerts and notifications using XML.

        ## How it works

        </Frame>

        Plivo requests an answer URL when the call is answered (step 4) and expects the file at that address to hold a valid XML response from the application with instructions on how to handle the call. To see how this works, you can use [https://s3.amazonaws.com/static.plivo.com/broadcast.xml](https://s3.amazonaws.com/static.plivo.com/broadcast.xml) as an answer URL to test your first outgoing call. The file contains this XML code:

        ```xml theme={null}
        <Response>
        <Speak>Congratulations! You have made your first bulk call.</Speak>
        </Response>
        ```

        This code instructs Plivo to say, “Congratulations!  You have made your first bulk call” to the call recipients. You can find the entire list of valid Plivo XML verbs in our [XML Reference](/voice/xml/overview/) documentation.

        ## Prerequisites

        ## Create voice alert broadcast application

        Create a file called `Broadcast.go` and paste into it this code:

        ```go theme={null}
        package main

        import "fmt"
        import "github.com/plivo/plivo-go/v7"

        func main() {
        	client, err := plivo.NewClient("<auth_id>","<auth_token>", &plivo.ClientOptions{})
        	if err != nil {
        			fmt.Print("Error", err.Error())
        			return
        		}
        	response, err := client.Calls.Create(
        		plivo.CallCreateParams{
        			From: "<caller_id>",
        			To: "destination_number1<destination_number2",
        			AnswerURL: "https://s3.amazonaws.com/static.plivo.com/broadcast.xml",
        			AnswerMethod: "GET",
        		},
        	)
        	if err != nil {
        			fmt.Print("Error", err.Error())
        			return
        		}
        	fmt.Printf("Response: %#v\n", response)
        }
        ```

        Replace the auth placeholders with your authentication credentials from the [Plivo console](https://cx.plivo.com/home). Replace the phone number placeholders with actual phone numbers in [E.164 format](https://en.wikipedia.org/wiki/E.164) (for example, +12025551234).

        <Note>
          <strong>Note:</strong> We recommend that you store your credentials in the `auth_id` and `auth_token` environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and it will automatically fetch them from the environment variables. You can use `os.Setenv` and `os.Getenv` to store environment variables and fetch them when initializing the client.
