You can reject incoming calls 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 use a Plivo XML document that rejects incoming calls on a Plivo number. ## How it works Inbound Call Flow

Plivo requests an answer URL when it answers the call (step 2) and expects the file at that address to hold a valid XML response from the application with instructions on how to handle the call. In this example, when an incoming call is received, Plivo rejects the call using the [Hangup](/voice/xml/hangup/) XML element. ## 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. You must have a voice-enabled Plivo phone number to receive incoming calls; you can rent numbers from the [Numbers](https://cx.plivo.com/phone-numbers) page of the Plivo console, or by using the [Numbers API](/numbers/). 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 an application to reject incoming calls Create a file called `reject_call.js` and paste into it this code. ```js theme={null} var express = require('express'); var plivo = require('plivo'); var app = express(); app.set('port', (process.env.PORT || 5000)); app.all('/reject_calls/', function(request, response) { var response = plivo.Response(); var params = { 'reason': 'rejected' }; response.addHangup(params); res.writeHead(200, {'Content-Type': 'text/xml'}); res.end(response.toXML()); }); app.listen(app.get('port'), function() { console.log('Node app is running on port', app.get('port')); }); ``` ## Create a Plivo application to reject calls Associate the code you created with Plivo by creating a Plivo application. Visit Voice > [Applications](https://cx.plivo.com/xml-applications) in the Plivo console and click on **Add New Application**, or use Plivo’s [Application API](/account/api/application/#create-an-application). Give your application a name — we called ours `Reject Call`. Enter the server URL you want to use (for example `https://.com/reject_caller/`) in the `Answer URL` field and set the method to `POST`. Click **Create Application** to save your application.

## Assign a Plivo number to your application Navigate to the [Numbers](https://cx.plivo.com/phone-numbers) page and select the phone number you want to use for this application. From the Application Type drop-down, select `XML Application`. From the Plivo Application drop-down, select `Reject Call` (the name we gave the application). Click **Update Number** to save. Assign Phone Number to Reject Call App

## Test Make a call to your Plivo number using any phone. Plivo will send a request to the answer URL you provided requesting an XML response and then process the call according to the instructions in the XML document the server provides — in this case, rejecting it. ## Overview When you don’t want to receive incoming calls on your Plivo numbers, follow the instructions in this guide to create an application to reject them.

If this is your first time using Plivo APIs, follow our instructions to [set up a Ruby development environment](/sdk/server/set-up-go-dev-environment-api-xml-voice/) and a web server and safely expose that server to the internet. ## Create a Rails controller to reject incoming calls Change to the project directory and run this command to create a Rails controller to reject incoming calls. ```shell theme={null} $ rails generate controller Plivo voice ``` This command generates a controller named plivo\_controller in the app/controllers/ directory, and a view will be generated in app/views/plivo directory. We can delete the view as we don’t need it. ```shell theme={null} $ rm app/views/plivo/voice.html.erb ``` Open the file app/controllers/plivo\_controller.rb and paste this code in the PlivoController class: ```rb theme={null} include Plivo include Plivo::XML include Plivo::Exceptions class PlivoController < ApplicationController def reject r = Response.new() params = { 'reason' => 'rejected', # Specify the reason for hangup } r.addHangup(params) xml = Plivo::PlivoXML.new(r) render xml: xml.to_xml end end ``` ## Create a Plivo application to reject calls Associate the Rails controller you created with Plivo by creating a Plivo application.

Edit the app/http/controllers/voiceController.php file and paste into it this code. ```php theme={null} 'rejected', # Specify the reason for hangup ); $r->addHangup($params); Header('Content-type: text/xml'); echo $r->toXML(); } } ``` ## Create a Plivo application to reject calls Associate the controller you created with Plivo by creating a Plivo application.

Give the project a name — we used `Rejectcall`. Navigate to the Controllers directory in the Rejectcall project. Create a controller named RejectcallController.cs and paste into it this code. ```cs theme={null} using System; using Plivo.XML; using System.Collections.Generic; using Microsoft.AspNetCore.Mvc; namespace Rejectcall { public class RejectcallController : Controller { public IActionResult Index() { Plivo.XML.Response resp = new Plivo.XML.Response(); // Add Hangup XML Tag resp.AddHangup(new Dictionary() { {"reason","rejected"}, // Specify the reason for hangup }); var output = resp.ToString(); return this.Content(output, "text/xml"); } } } ``` ## Create a Plivo application to reject calls Associate the controller you created with Plivo by creating a Plivo application.
