Hi Twilio developer evangelist here.

Can you try modifying your view to look like this instead?

<?xml version="1.0" encoding="UTF-8" ?>
<Response>
    <Dial callerId="@ViewBag.CallerId">
        @Html.Raw(ViewBag.NumberOfClient)
    </Dial>
</Response>

Remember XML is case-sensitive, so the casing in your XML tags actually matter. Also, I would suggest using the Twilio.TwiML helper library. With that, you can get your XML generated for you with the right casing, and avoiding typos altogether.

Here's how you'd do it:

var twiml = new TwilioResponse();
var dialAttributes = new {callerId = "48326304351"};

var dial = twiml.Dial("+15555555555", dialAttributes);
return TwiML(dial);
