Fw: TLV and VoiceXML

["David Webber \(XML\)" <david@drrw.info>]

Folks,

Mark Headd here is interested in working with us on
VoiceXML and EML.

This is a really significant opportunity IMHO.

Who out there has some test data from a ballot EML
that they would be interested in sharing with Mark so
that we can setup a possible web demonstration?

If you are in the USA - you can call 1-800-TELLME
for a live production system that shows just how
powerful VoiceXML is.

Thanks, DW

p.s. Mark also sent me this technical article link to VoiceXML
       http://studio.tellme.com/dom/howto/using_data.html
       where we can potentially feed data from an EML XML
       instance via a URL....
