Gotcha. What does your script(s) look like? Can you post them or provide screenshots? Have you uploaded any files to UCCX Admin > Applications > Grammar Management yet? Right now, does your script recognizes the spoken authorization code? Launch the CCX Editor. Under the [Debug] tab, run the Reactive Script. Walk through the script, step-by-step and see what happens after the caller speaks the authorization code.
EDIT: Just to clarify... If UCCX and Nuance is configured properly; meaning, after you configure the ASR/TTS settings, start the ASR/TTS services, upload the Grammars, add the Simple Recognition step into your script and then, use this step to "tag" the key words/letters/numbers from the list of available Grammar(s). The other option is... using the Generic Recognition step, along with the Get Recognition Result Info and Get Recognition Interpretation steps to create a complex speech dialog.
If you want to play the authorization code back to the caller, then simply use the Prompt step. If you're licensed for TTS, you can change the prompt value from P[ ] to TTS[ ] and then, you can reference the authorization code inside the TTS[ ] prompt. For example; TTS[ grammarSpokenAuthCode ]
Another option is changing the prompt value from P[ ] to S[ ] which stands for spelling. In this case, the system will breakdown the string of characters and read back each character, one-by-one.
Honestly, it sounds like you're missing Grammars and/or "tags" from your Simple Recognition step or you should review the Generic Recognition step.
