Current issues with the Avaya VoiceXML feature
Application developers should consider the following issues when developing VoiceXML applications for the AVvoicexml package:
- Redefining a variable that was set previously changes the value of the variable.
- Formats of data in the say-as tag must conform to the Text-to-Speech engine being used. See the appropriate vendor documentation for SSML and say-as tag support.
- session.connection.local.uri contains the same value as session.telephone.dnis.
- session.connection.remote.uri contains the same value as session.telephone.ani.
- transfer bridge="true" is not supported for a VoIP configuration.
- maxnbest and confidencelevel are supported for advanced speech recognition (ASR) grammars only. Maxnbest and confidence level are not supported for word pair ASR grammars. An example of word pair ASR grammars is: <grammar> one | two | three </grammar>
- Certain elements of the VoiceXML 2.0 specification are not supported by the AVvoicexml package. For more information, see Unsupported features of the VoiceXML 2.0 specification for the AVvoicxml package.
Application developers should consider the following when developing VoiceXML applications for the AVvoicexml and AVvoicxml2-0 packages:
- Only two-level objects are supported when semantic interpretation and slot expressions are returned as non-scalar values
