I've been using OD for several years, but never had to do more than rudimentary programming. I'm with a new company and now I'm trying to connect to their back end services using their existing GovXML code (see attached) that they used from their legacy IVR, but I'm not sure how to use or incorporate that into OD. Any assistance and guidance would be greatly appreciated.

This looks like a regular xml file that has content for a particular system. OD is about generating voice xml for the voice browser. I don't know how these 2 can mix.

It's possible to Integrate a third-party VXML subdialog, here for Release 7.2.3 page 71:

Wilson,
So...I get that I wouldn't be able to simply import the sample file...but does that mean it can't be modified to a VXML file? (Assuming I knew VXML).

And I think Massimo answered my next question, "Now that I have a VXML file, what do I do with it?"

But the file you are showing is not VXML. If you have an vxml file, you can just use the Import function to make it a reusable module. You can find the information in the DevGuide doc for reusable modules.

So suppose I have this vxml file called hello.vxml:

<vxml version="2.1" xmlns="http://www.w3.org/2001/vxml" xml:lang="en-us">
<form id="helloWorld">
<block>
<prompt bargein="true" bargeintype="speech" timeout="8000ms">
<audio src="http://10.25.40.32:7080/vxmlTest/data/english/phrases/helloWorld.wav">Hello world</audio>
</prompt>
</block>
</form>
</vxml>

and I want to use this instead of using the typical announcement node, what would be the process to import this in OD? Since this isn't a .war file. Is that possible?

You can just use the "Manually define module definition" option which leads to the page where you enter the URL to the file and define parameters if there is any.
