"MRCP 407" error

Justin Dupree -

This error effectively means Tropo made a request, and got nothing useful back - kind of generic, unfortunately.  It is most commonly associated with broken grammars, or no grammar at all, for example an ask with no choices 

ask("What's your four or five digit pin? Press pound when finished", {
    onChoice: function(event) {
        say("Thank you");

It can also mean you're attempting to send a text message, but there isn't an SMS enabled phone number attached to your application. Without one of those numbers attached to an app, text messaging is not enabled (inbound or outbound).

Finally, It can also mean the "name" field is undefined with WebAPI and an "ask". Without it, the choice value can't be properly aligned in the result JSON.
