Can not get @billsimon Transcribe with Azure working

[gregorywest]

I have just installed and got limping @billsimon script (https://github.com/simontelephonics/transcribe-with-azure). I can verify the script is limping. I have added some diagnostic code to get a status back. So I can see the main body of the code is being executed, but I am not getting back anything for the transcription.

Not exactly sure why it is not transcribing. When I get a voice mail, the eMail has the following line:
Transcription Voice Mail Found
I am not sure where to start looking for the issue.
