Twilio Outgoing calls using web API
<p>I want to develop Application in C# using Twilio for outgoing calls. I have created Web API which returns XML and deployed it on Azure website. The URL which is generated I passed it in my code for making outgoing calls. </p>

<pre><code>var call = client.InitiateOutboundCall(fromNumber, toNumber, "http://callpoc.azurewebsites.net/api/response");
</code></pre>

<p>but I am unable to change the voice of outgoing calls.</p>
