Difference in VXML built-in grammar behavior

Problem Summary VXML built-in grammar behavior difference in DTMF, and DTMF with Voice Modes
Error Message None
Possible Cause Difference in behavior is because DTMF alone is processed locally by VVB, which is as per www.w3.org/TR/voicexml20/#dmlABuiltins.

Whereas mixed (DTMF with voice) and voice mode built-in grammar are dependent on ASR Server Platform (for example, Nuance and it associated locale package).

For ASR Server (Nuance) platform behavior and limitation on built-in grammars, contact Nuance customer care.

Recommended Action None


Release Release 11.0(1)
