<?xml version="1.0" encoding="UTF-8"?>
<Response>

</Response>
SendDtmf sendDtmf = SendDtmf.builder()
.digits("12w34")
.build();
Response response = Response.builder().build()
.add(sendDtmf);
Response response = new Response();
SendDtmf sendDtmf = new SendDtmf();
sendDtmf.Digits = "12w34";
response.Add(sendDtmf);
Console.WriteLine(response.ToBXML());
response = Bandwidth::Voice::Response.new()
send_dtmf = Bandwidth::Voice::SendDtmf.new({
:dtmf => "12w34"
})
response.push(send_dtmf)
puts response.to_bxml()
response = Response()
send_dtmf = SendDtmf("12w34")
response.add_verb(send_dtmf)
print(response.to_bxml())
var sendDtmf = new BandwidthBxml.Verbs.SendDtmf();
sendDtmf.setDtmf("12w34");
var response = new BandwidthBxml.Response();
