During one of the sessions I was in this week, Intervoice mentioned that they were going to launch some dialog controls that would be available as add-ins to go with the SDK. I just found the press release for the announcement.

The web site for the controls isn't live yet, but as soon as it is I'll take a look. (It should be at http://developer.intervoice.com) It is really exciting to see a broader developer ecosystem starting to evolve.
