I'm getting an error of type:

My code validates, but I'm still getting the error. I'm new to this and could use some help, any suggestions?

error.recognition.nogrammars- undefined grammars in IVR code

Post by support »

Hello:

The reason you are getting error.recognition.nogrammars is because you have no IVR grammars defined within your IVR code. When you prompt a user for input, you have to specify the constraints of the input.

try changing your <field> tag to:

Code: Select all

<field name="listenToTicketField" type="digits?length=1">



Hope this helps! :)
