Connect an inbound call
In this code snippet you see how to connect an inbound call to another person by making an outbound call.
Example
Replace the following variables in the example code:
Key | Description |
---|---|
VONAGE_NUMBER |
Your Vonage Number. E.g. 447700900000
|
YOUR_SECOND_NUMBER |
The number you are connecting to. E.g. 447700900002
|
Prerequisites
A Vonage application contains the required configuration for your project. You can create an application using the Nexmo CLI (see below) or via the dashboard. To learn more about applications see our Vonage concepts guide.
Install the CLI
npm install -g nexmo-cli
Create an application
Once you have the CLI installed you can use it to create a Vonage application. Run the following command and make a note of the application ID that it returns. This is the value to use in NEXMO_APPLICATION_ID
in the example below. It will also create private.key
in the current directory which you will need in the Initialize your dependencies step
Vonage needs to connect to your local machine to access your answer_url
. We recommend using ngrok to do this. Make sure to change demo.ngrok.io
in the examples below to your own ngrok URL.
nexmo app:create "Connect Inbound Call Example" http://demo.ngrok.io/webhooks/answer http://demo.ngrok.io/webhooks/events --keyfile private.key
npm install express
Create a file named connect-an-inbound-call.js
and add the following code:
const app = require('express')()
Write the code
Add the following to connect-an-inbound-call.js
:
const onInboundCall = (request, response) => {
const ncco = [{
action: 'connect',
from: VONAGE_NUMBER,
endpoint: [{
type: 'phone',
number: YOUR_SECOND_NUMBER
}]
}]
response.json(ncco)
}
app.get('/webhooks/answer', onInboundCall)
app.listen(3000)
Run your code
Save this file to your machine and run it:
node connect-an-inbound-call.js

Add the following to `build.gradle`:
compile 'com.vonage:client:5.5.0'
compile 'com.sparkjava:spark-core:2.7.2'
Write the code
Add the following to the main
method of the ConnectInboundCall
class:
/*
* Route to answer incoming calls with an NCCO response.
*/
Route answerRoute = (req, res) -> {
ConnectAction connect = ConnectAction.builder()
.endpoint(PhoneEndpoint.builder(RECIPIENT_NUMBER).build())
.from(VONAGE_NUMBER)
.build();
res.type("application/json");
return new Ncco(connect).toJson();
};
Spark.port(3000);
Spark.get("/webhooks/answer", answerRoute);
Spark.post("/webhooks/answer", answerRoute);
Run your code
We can use the application
plugin for Gradle to simplify the running of our application.
Update your build.gradle
with the following:
apply plugin: 'application'
mainClassName = project.hasProperty('main') ? project.getProperty('main') : ''
Run the following gradle
command to execute your application, replacing com.vonage.quickstart.voice
with the package containing ConnectInboundCall
:
gradle run -Pmain=com.vonage.quickstart.voice.ConnectInboundCall

Install-Package Vonage
Create a file named ConnectInboundCallController.cs
and add the following code:
using Vonage.Voice.Nccos;
using Vonage.Voice.Nccos.Endpoints;
Write the code
Add the following to ConnectInboundCallController.cs
:
[Route("webhooks/answer")]
public string Answer()
{
var YOUR_SECOND_NUMBER = Environment.GetEnvironmentVariable("YOUR_SECOND_NUMBER") ?? "YOUR_SECOND_NUMBER";
var VONAGE_NUMBER = Environment.GetEnvironmentVariable("VONAGE_NUMBER") ?? "VONAGE_NUMBER";
var talkAction = new TalkAction()
{
Text = "Thank you for calling",
VoiceName = "Kimberly"
};
var secondNumberEndpoint = new PhoneEndpoint() { Number=YOUR_SECOND_NUMBER};
var connectAction = new ConnectAction() { From=VONAGE_NUMBER, Endpoint= new[] { secondNumberEndpoint } };
var ncco = new Ncco(talkAction,connectAction);
return ncco.ToString();
}

Try it out
You'll need to expose your server to the open internet. During development you can use a tool like Ngrok to do that.
When you call your Vonage Number you will automatically be connected to the
number you specified in place of YOUR_SECOND_NUMBER
.
