how can I call a webservice from voiceXML?

I'm building a very simple voiceXML app to allow people to make recordings. But first, I need to authenticate callers by phone number and/or PIN.

Can I call a webservice from voiceXML? Looks like I want to use the voiceXML "data" element to call my webservice. However, I need to dynamically calculate the URL, and it looks like it only takes a static string as the "src" parameter.

I'm new to voiceXML, so pointing me to a good tutorial would help too! I'm working from the voxeo documentation.

Solution

  • you're right about needing the data element, and i'd have a look at the screxpr attribute of that element.

    pretty self-explanatory:

    <data srcexpr="'http://example.com/?key=' + myValue" />
