Part II: Developing Outbound Applications: Generate VXML File And Send it to the Gateway | Gateway Tutorial

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.

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>

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;
                }
