Generate vxml file and send it to Gateway

Since the call message includes dynamic information, we cannot pre-install the vxml file to the gateway as we did in the first version of the sample.

1. Generate the vxml file

In callnowDlg.cpp, the method GenerateVxml() generates the vxml file based on the message in the dialog. The result vxml is like the following:

<?xml version="1.0"?>
<vxml version="1.0">

<form id="td">
  <block>
    <audio src="callnow/hello.wav"/>
    ... message in the dialog box ...
  </block>
</form>

</vxml>

2. Send the vxml file to the gateway

The following code creates a directory under the gateway call scheduler directory and sends the newly created vxml file over.

CString targetdir = "\\outcall\\webapps\\" + GetClientName() + "\\";
VgateClient::CreateDir(targetdir);
if (! VgateClient::SendFile("callnow.vxml",
                            targetdir + "\\callnow.vxml",
                            false))
{
    AfxMessageBox(VgateClient::GetLastError());
    return;
}
