We have a CVP application that needs to accept a fairly complicated set of digits, and an elegant design solution involved the use of a DTMF grammar.
Upon deployment, we are seeing that this results in an ASR license being allocated to this call, even though it is a DTMF-only application.
Is there a way to utilize a DTMF grammar without having the system use an ASR license? We are trying to specify that the caller can enter a valid menu option (1-4, *) OR a 6-digit extension number at the input. A DTMF grammar allows this to be done with leveraging the application standards processing for invalid inputs, which is clean.
