Twilio is not making call

Danish Habib

11y2k.NET

I am using that markup

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="twilio.WebForm1" %>

<%--

style="height: 26px" />--%>

Fill in all fields and click Make this call.

To:

Message:

onclick="callpage_Click" />

my code behind is that

protected void callpage_Click(object sender, EventArgs e)

{

// Call porcessing happens here.

// Use your account SID and authentication token instead of

// the placeholders shown here.

string accountSID = "myid";

string authToken = "mytoken";

// Instantiate an instance of the Twilio client.

TwilioRestClient client;

client = new TwilioRestClient(accountSID, authToken);

// Retrieve the account, used later to retrieve the

Twilio.Account account = client.GetAccount();

string APIversuion = client.ApiVersion;

string TwilioBaseURL = client.BaseUrl;

this.varDisplay.Items.Clear();

if (this.toNumber.Text == "" || this.message.Text == "")

{

this.varDisplay.Items.Add(

"You must enter a phone number and a message.");

}

else

{

// Retrieve the values entered by the user.

string to = this.toNumber.Text;

string myMessage = this.message.Text;

// Create a URL using the Twilio message and the user-entered

// text. You must replace spaces in the user's text with '%20'

// to make the text suitable for a URL.

String Url = "https://demo.twilio.com/welcome/voice/?Message%5B0%5D="

+ myMessage.Replace(" ", "%20");

// Display the endpoint, API version, and the URL for the message.

this.varDisplay.Items.Add("Using Twilio endpoint "

+ TwilioBaseURL);

this.varDisplay.Items.Add("Twilioclient API Version is "

+ APIversuion);

this.varDisplay.Items.Add("The URL is " + Url);

// Instantiate the call options that are passed

// to the outbound call.

CallOptions options = new CallOptions();

// Set the call From, To, and URL values.

options.From = "+15016536555";

options.To = to;

options.Url = Url;

// Place the call.

var call = client.InitiateOutboundCall(options);

this.varDisplay.Items.Add("Call status: " + call.Status);

}

Myid and mytoken is replaced by origional values but i am not getting call ?call.status shows null

Hi,
See the below code(Using for verifying my phone no)

protected void callpage_Click(object sender, EventArgs e)
{
// Find your Account Sid and Auth Token at twilio.com/user/account
string accountSID = ConfigurationManager.AppSettings["ACCOUNT_SID"];
string authToken = ConfigurationManager.AppSettings["AUTH_TOKEN"];
// Instantiate a new Twilio Rest Client
var twilio = new TwilioRestClient(accountSID, authToken);
// Use the Twilio-provided site for the TwiML response.
String Url = "http://demo.twilio.com/docs/voice.xml";
// Build the parameters
// Instantiate the call options that are passed to the outbound call
CallOptions options = new CallOptions();
// A phone number you have previously validated with Twilio
options.To = to;
// The number of the phone receiving call
options.From = "+15016536555";
options.Url = Url;
options.Method = "GET";
options.FallbackMethod = "GET";
options.StatusCallbackMethod = "GET";
options.Record = false;
// Make the call.
var call = twilio.InitiateOutboundCall(options);
if (call.RestException == null)
{
Response.Write(string.Format("Started call: {0}", call.Sid));
}
else
{
Response.Write(string.Format("Error: {0}", call.RestException.Message));
}
}

Hi Danish,

I am using Twilio account for verifying user phone number. You can verify phone number by using this code snippet.

string accountSid = ConfigurationManager.AppSettings["TwilioAccountSid"].ToString();
string authToken = ConfigurationManager.AppSettings["TwilioAuthKey"].ToString();
//get number which provided by twilio
string twilioNumber = ConfigurationManager.AppSettings["TwilioNumber"].ToString();
//create twilio client
//it is responsible for twilio call
var client = new Twilio.TwilioRestClient(accountSid, authToken);
string userNumber = "+15016536555";
//get autoriztion code which need to be for user authorization
Random random = new Random();
string pinCode = (random.Next() % 90000 + 10000).ToString();
//voice message
string message = "Welcome%20to%20MYAPP.%20Your%20authorization%20code%20is%20" + HttpUtility.UrlPathEncode(String.Join(" ", pinCode.ToString())) + "&";
//voice call url
string content = "http://twimlets.com/message?Message%5B0%5D=" + message + "";
//call option which is used to provide caller phone no and twilio url for call
var options = new Twilio.CallOptions();
options.Url = content;
options.From = twilioNumber;
options.To = userNumber;
options.Method = "GET";
options.FallbackMethod = "GET";
options.StatusCallbackMethod = "GET";
// call
var callResponse = client.InitiateOutboundCall(options);
if (!object.Equals(callResponse.Sid, null))
{
// Call Success.
}
else
{
//Call Fail.
}
